Elvis, the bullets that you powder coated and heated to 400 will test a lower bhn for a couple days but will return after about a week to the original bhn before heating them in the oven. Using 3 separate bhn testers I checked this on 19bhn bullets. After cooking on 400 for 20 min I then rechecked them on day 2/3/4/5/6/7 and all on day 7 had returned to within 1 bhn of cast hardness. Just what I have found.
Something else to consider is the bhn test. It is putting an indentation in the surface. The coating is a very thin layer and softer than the lead itself therefore your bhn test on the coated bullets are not accurate. This is why I put non coated bullets in to heat with my coated ones and these are the ones you need to test and they will tell you what u need to k ow
Thank you very much for this comment seems very underrated and unnoticed in the chat
I love it. Documentation, the difference between an anecdote, and science. Thanks for the great vids Man.
I gotta say thanks for the info in the latest video elvis. I only cut my temp back to about 300 but what makes it so awsome is afterward i felt good about takin my rifle bullets out right after the powder coating flows over the bullets. Sure enough after the first load i observed what u said about the bullets easy release from the tray when i dumped the bullets into the quench. on my second load of rifle bullets i just tossed them all in the basket like pistol bullets. To my overwelming joy they all came out perfect just like i had placed all my rifle bullets on the tray carefully making sure that they didnt touch. So now im saving alot of time and aggravation when coating my rifle bullets. Thanks for all the great work you do and share with us all.
Since i discovered your channel its become my favorite on youtube. Inicially it was the everyman approach thats so refreshing and inviting. That is still the case. the info and the process you use make your videos enlightening, second to none. I believe the simple and honest why or why not questions are not asked enough by most but you sir have not lost that inquisitive nature. you continually demonstrate that the solutions to most problems are small quests. Just a simple matter of the can do spirit, effort and common sence. Put simply anything is possible if you just try. For most unbridled possibility is a natural instinct that is dimmed by the sinacism developed with time. Your enjoyment of life and its journey is evident by the laughter and joy you show in every video. You are an inspiration on so many levels.
Thanks again and dont ever change.
Those bullets are not straight in the cases .
I watch just to hear you say "Hey RUclips! It's Elvis Ammo here! Hey!" Always puts a smile on my face.
Xaro Xhoan Daxos ... cool! I'll take it.... glad ya stopped by. ; )
Between your other "marathon" video on powder coating bullets, and this one, I have to say that these two videos are the most informative and useful videos I've yet seen on the subject.
Thank you sir!
This is the best method so far, did a pile of 9mm boolits today and they came out great and broke right apart.
I have piles of boolits for .357, .44 and .45 to do and this is how they will be done
You are a pioneer of casting! Thanks for what you do.
64samsky ..hey bud... thanks.. just hope I'm pioneering something we can all use that works! ; )
You've hooked me on powder coating. Best is once their coated I'm no longer handling lead. The lower temps and times are very important too. I'm "off grid" and my reload room is in my shop, separate from the house. I have to run a small generator to use my toaster oven.
Hey Ol' Reprobate.. Nice name by the way! : ) Less energy is a perk for sure! Thanks for taking the time to comment.....
Hey Cat thank you for this Video. I've wondered about this before but had no way to test hardness. You are on the cutting edge of our endeavor to find new and better ways.
Thanks!
This may even be a benefit to us crazy people that stand our bullets one at a time ...... the heat can get to the coating faster and does not need to penetrate the lead on one to heat the next one. Hmmmmm something to think about (I get in trouble when I think, I try not to do it much) .
All kidding aside, you may have discovered something that will help all of us and I for one appreciate the time and effort you must have put in to this. THANK YOU!
Great work, Elvis...!! Other commenters have been saying that PC works with shorter oven times, but you're pushing new ground with the lower temps... Gung Ho...!!
FortuneCookie45LC .. Yeah.. some crazy stuff with unexpected results so far.. Some more data and testing is needed. I'm sure I won't be the only one with good feedback.. I'm excited about what I'm seeing. . this could be a great option to control our bhn. More to come! ; )
Elvis - I was just putting another order in with Eastwood, so I bounced your PC bullets off of 'em just to get info from the source to add to yours...They said that the 400 for 20 minutes was the recommendation for car parts. But the tech said that doing other stuff like bullets, the temps and times could certainly be adjusted. What he said is that if it works, it's OK. Have a great day, FC Steve
FortuneCookie45LC ..Yeah, I guess I was never much for following the rules huh! ; ) I have an epoxy base pc coming. it's a much lower temp cure.. Might be just what we're looking for. My biggest hope is that it coats using the swirl method! ; ) a lot of times when someone says "no way" it just means they haven't tried anything different! thanks for the feedback from Eastwood. ...
@@elvisammo Based on several bullet casting books that I've read on the subject, wheel weight is nearly devoid of TIN. It does have about 4% antimony on average. The amount of gain from quenching wheel weight is minimal.
It would be better to add about 1%-2% of TIN. This will improve BHN after quenching.
According to the technicians at Lyman water quenching only put a surface hardness on the bullet and when you size them it takes the surface off so you have really gained anything by water quenching
I did experiment with powder coating my .25 cal slugs and pellets for my air guns.I did them at 160 degrees for 20 minutes and they turned pretty good.This was the first time I did it.I have a 350 Legend on the way and plan to cast bullets for it.I also have plans on getting a 450 BushMaster.
Hey Elvis I know this vid is a little old but I have another tip for Powder coating. Bake the bullets on non stick foil on a small cookie sheet. When the timer goes off take them right away and put them on a large cookie sheet and roll them around till they cool a little. This is how I do mine and get no flat spots or bullets sticking together. Give it a try. I see everyone waiting till they are cooled down then breaking them apart. This method works great and is much easier. Thanks for the great vids.
All I can do is thank you Elvis! you do the work, and we reap the benefits!! awesome!
Joe P ... Yes sir ... you guys keep coming by I'll keep sharing the madness! ; ) thanks for participating!
Great research brother, very good to know. I had noticed that after about 12-15 mins in the toaster oven that my cast bullets looked finished, but thought maybe the extra time in the oven was part of the powder coat curing process. Looks like the extra time us not required at all, also was tempted to reduce the heat but never tried that either. Don't forget your safety glasses when pounding out those bullets, a lot there that could fragment and wind up in one of the eyes. Again awesome work dude. Thanks a million.
Thank you for putting so much effort into these for us. Really enjoy your efforts... thanx
Great stuff. Looking forward to the follow-up. I haven't started powder coating yet, but this is where I'm learning. Thanks
you will kick it off right when ya get started Rick LeClair.. Warning. Its addictive! : )
Very Nice! Good work Elvis, Your hard work and testing is appreciated by all of us that are powder coating like me. Thanks again. I am binge watching your vids to save me a ton of time and misspent money Thanks to your EARL laboratory :)
I feel like I’m watching a revolutionary legend in real time, like you’re gonna do big things when you grow up😎
Thanks Elvis , I have been playing with the time ( down to 12 min. ) but have left the temp . at 400 degrees . Looks like you took it a step farther . I will give this a try . Thanks for sharing .
Hey James Pollard... Yeah.. Fortune Cookie said that somebody was shortening the bake time! you must be one of those! One thing I did was let the oven get up to 260 and lost about 3 or 4 BHN. I was getting close to the end.. I should have pulled them out. Thats how close the 250 is to tempering. just thought you should know.. that temp formula I was holding up is pretty good!
Thanks for sharing all your information with us.
Hi. Thanks a lot for your assume tutorial videos. Im new in the way of coating bullets. Actually i haven’t done it yet. So I’m learning, and you taught in a very pedagogical way. By the way, your accent is very nice. Me myself live close to the North pole. Scandinavia. Thanks Elvis. 😊👍🏻
Greetings Peder
Thanks for sharing this. I don't PC because of the BHN loss. Now I have to try it out again thank you
toby emerson ..that's awesome! I knew you folks were out there! Thanks so much for taking the time to comment. . I was hoping to here from you guys!!! ; )
I recently tried pc on 130 grain 308 win bullets at 2500 ft/sec and had excellent performance and no leading. I could smell the burned pc though.
Hey Elvis ! First let me say this I can't thank you and F.C. with Johnny also for what you guys do ,with the help you guys give Us in this .I will pass this along to all my reload freinds (just make them think I am smart ) not ! thank you again My God Bless You and Yours .
You do such a great job on your video's and can't wait to see more.
Great job on figuring out time and temperature for keeping your bullets hard while curing the powder the bullets look grate...shake and bake is the best method the elvisammo method 👍
Two questions:
1) Did you do a BHN test on your powder coated bullets that were water hardened out of the mold, cooked the usual 450* method, THEN water quenched out of the oven? I wonder if water quenching then after the cook restores any of the hardness.
2) Since we are powder coating the bullets, does the actual bullet hardness matter anymore? My purpose in casting hard bullets is as a substitute for lube, and preventing barrel leading.
2a) In fact, would a softer powder coated bullet actually be beneficial, as it would be able to better expand under pressure to form a better seal to the barrel?
Outstanding research Elvis. You are a pioneer. This is great news for PC rifle bullets. Thank you sir.
Hey Elvis, seems great minds think alike. I've been doing a similar process all along. I usually set mine to around 275* for about 10 minutes. I'll lower it to 250* and try to keep a little more bhn. I use a mixture of range scrap and ww since ww are hard to come by in my area.
Great news Elvis thank you so much I'm going to make a batch this weekend of 30 cal 150gr and will try your new method on 100 of them if it kicks but for me I'll do the other 900 the same method. Keep these videos coming. You da man!
NYC Reloader Yeah! good deal... if ya get em done this weekend, I'd be glad to hear your thoughts! happy shooting bud!
elvis ammo I shot them this weekend and they shot great. Really tight groupings and my barrel check with my borescope looks fine as well. This method seems to work well. I'll do some more testing.
Awesome Information and Progress from EARL. Thank you for being so generous of your time and with your valuable information.
Awesome, brother. I've been following you and the methods are sound. I'm partial to the Eastwood semi-gloss Black.
Bullets look like the old Federal Ny-Clads. Can't wait to try the new technique. Thanks for your efforts.
Michael Cinardo ..your welcome. .. how easy is that powder to apply? quick shake and bake? love to hear more.
Elvis ammo your becoming real legend thanks for another great video
To soften is to anneal. Tempering is hardening. Excellent job and repeatable scientific method. Thank you man!
tempering is a 2nd heat treat at lower heat after 1st hardening at high heat
Hey Elvis, I tried your method today and have to say that it works great. Although, I don't have a BNH testing device to check hardness. Thanks again.
Thanks Mick9mm.. for the info you do have. Nice to know it can be duplicated! : )
Wondering if powder coating produces advanced wear on barrel. Paper patch bullets wear the barrel though one would think paper wears hard iron or steel? But people have written about it. Wonder if whatever the coating is made from will produce accelerated barrel wear? For the average hunter shooting a few rou ds to check zero then whatever is shot during probably not. Hobby shooters shooting few hundred a month...probably but serious shooters shooting 500 a week maybe do....
Well, the powder coating should be softer than the lead. I would guess no. But who knows
My contention with water quench directly from cast is that antimony stays in solution apart from chemical mixture combination and crystallizes upon rapid cooling. Then when firing the pure lead coating the antimony crystals rub off into the rifling grooves upon firing. Hence the use of tin to eliminate the colloidal dispersion through chemical combination. (Just like adding alcohol to gasoline to break up frozen gas lines in winter.
Love your videos bro and your intro has to be the Best 1 yet good luck on your channel and thank you for providing us with GREAT videos
Thanks pedro ramos... much appreciated! and my pleasure! : )
Just got into reloading again going to try my hand at casting im so glad I found this video and thank you for the tip =)
I like your style! Your metallurgical theory holds water.
heattreating the lead bullet in a oven was a method to hardening the bullet ,if you heat them to cure the bullet with powder coating ,just wat hotter and then up in cold water. seems to work wel too
yep peteralxben.... thats another option... I hear that can work good!
You were about to tell us the BHN difference before and after you water quenched the PC bullets at the lower temp at 18:55. Then you drifted to cotton on the bullets from a towel and you left out the BHN difference. It may help your viewers if you can outline your results down and show that to us in the video so you don't get sidetracked so much but I understand your excitement. We really appreciate the time you put into this. Thank you.
I have found if you heat them till they gloss over then 1-2 minutes longer is all that is needed. Large batch or small batch doesn't matter. That point where they move from fuzzy to glossy is the key not the time. Id have PCd the same quantity of bullets in 1 batch, but, moved them from the oven to a water bath, thinking I could preserve some of the hardness. They seem to shoot fine subsonic 800-1100 fps. I don't know about faster. You are right, good powder makes all the difference.
Powder coat can be cured by hot air or a Halogen lamp and it only needs to get hot enough for the coating to melt without heating the lead much.
And I don't remember you saying if water quenching after powder coating restored any of the hardness, so did it?
What is the Brinell number for the quenched bullets? Thanks for your work and shaing.
EA . I have watched you and Uncle Jim and Fortune Cookie with the powder coating . I dove in and got a 20 dollar toaster oven from Wallyworld and it works ! Thanks for showing us just how easy it is .
Nice job bud.........In the many many years of casting bullets using standard WW's, air cooled they'll average out around 9-10 BHN and water quenched I'll get 14-15 BHN. I've never hit 21 BHN which is about what air cooled linotype runs. I bought an LBT BHN tester from Veral Smith way back in the day (probably 1981) and it has a direct readout. I've tested and swapped bullets back and forth with guys who had the Lee and saw (sometimes) wildly varing results.........just my 2. Never tried the Saeco......
Thanks a lot another good video I'm thankful for all the fork you do
Hello Elvis. Long time. Good video. Now, I'm going to throw in a monkey wrench.
Physics - water quenching does indeed make cast bullets harder, but SUSTAINED hardness depends upon the composition of the alloy.
What is happening in the oven when powder coating amounts to "tempering". Water (or for steel, oil) initiates the contraction of the molecules. Reheating in the oven "removes" the brittleness of the metal and, after tempering, increases the durability of the metal. Note the word "metal" - still applies for lead. Tempering, by definition, removes SOME hardness BUT increases durability. The sustainability of hardness is dependent upon composition, and any remaining hardness is dependent upon the temperature of the "tempering" process. In other words, the least amount of heat is best. So, you've done well.
Now one more thing. "Reloaderman" has come up with a "wet" method for powder coating. Per 200 bullets (he's doing 9mm), use 2&1/2 cc's of powder. Toss in 3 cc's of acetone. Shake with lid on for 10 seconds. Repeat for seven seconds with lid off, and then scatter bullets on a drying tray till dry. Once dry (just a few minutes), bake in the oven as per usual (400 degrees for 20 minutes). Break apart and allow to air cool and repeat with a second coat. He says this does everything people talk about, but keeps powder out of the air and minimalizes use of powder. I'm thinking that second coat could undergo a water quench and end up with the best of both worlds. Want to check it out?.........
Really enjoyed your vid..could you consider in the future doing one comparing powder coating pure soft lead bullets with your wheel weight bullets ...with some range testing comparing accuracy and penetration ...that would be very interesting ...even with buckshot ...Thanks
Thank you once again for the great information Elvis. Will be giving this a try.
Justin Conklin ...let me know what ya come up with! don't go over 250 degrees. . move up slow! if it goes up to high to fast and you got a good gloss. it don't hurt to pull em out a minute or two early!
elvis ammo just so happens I have about 300 rounds ready to coat. I'll let you know how mine turn out.
Hey Elvis I tried your method and it works great. I tried something a little different though. I preheat the oven on 250 and put the bullets in. Drops the temp to 185. As soon as the oven temp gets back to 250 I set the timer on 10 minutes. The powder seems to melt well. It also passed the hammer test.
I have you considered setting the oven to 400 but try to limit the time the bullets are in the oven? Instead of 20 minutes maybe 10 minutes if you only need to look for the shine?
The tempering seems like a good thing to me as the bullets will be more likely to expand and create a larger wound channel (unless of course you are hunting rhinos in which case you need em hard for penetration). ;)
Spot on Elvis Ammo! It was kinda funny listening to you because the method you speak of is the exact way I've been doing it. Low temp (200-250) and just keep an eye on the shine. Great information for everyone!! Keep up the good work buddy!
HillBilly J .. cool beans hillbilly. ... so this sounds tried and true! thanks for taking the time to comment. .. any advice is helpful and welcome!
I been looking into this subject myself. I was wondering if just water quenching at the higher temp would keep it from changing the BHN.
hey The Reloader Dude... Water quenching after powder coating does nothing for the BHN. But it would be possible to heat treat them close to the melting point for a couple hours or more. Then quench.
Elvis, I have been casting and shooting cast bullets for over 40 years. in the end I found that wheel weights (led ones) are the best. I have tried tempering them and doing al kinds of things. I spent years shooting paper patch bullets and got good results. however shooting a powder coated bullet is much like shooting a jacketed bullet. I am therefore not convinced that hardness makes much difference. they are all too hard to expand well on game. my question is: the cast bullets that are for gas checks, do they work well with powder coating and no gas check? if I still have to gas check them, I don't see the point. how do you get the bases to be uniform, as most inaccuracies I have found are due to the bullet base irregularities. I hurts me to have to pay 30 bucks for gas checks. and I cant find a 30 cal mold that does not require them. what is your experience along these lines? steve from Texas
Look up (NOE molds), their HTC type molds are smooth wall for powder coated pills for just about all the major cals. I use a Lee mold gc for my 454 but not the 9,40,45 auto stuff. Not tried for rifle yet...I have millions of gc's for rifle and will probably use them up when the time comes up..
thanks. please start making videos again. I understand why you don't I think, but I really appreciate your take on things. thanks, steve g.@@cobia1794
This is very interesting. Why do the powder companies say 400 deg for 12 minutes.
20 min is a bit overkill. If you want to see exactly how much time you need, get powder coat "clear" and coat some bullets. They'll appear Snow white, then when you cook them sit and watch. They'll go from snow, to wet looking, to normal lead in just a couple minutes. You can watch in real time how long they actually need to cook.
Elvis you have done it again! Does the PC hold up as well on rifle bullets with your new method? I have heard of people water quenching out of the mold then PC and baking @400 for 20 min then re-quenching out of the oven to maintain the high bhn.
I have been buying powder from The Powder Coat Store on Amazon. Their instructions say 400 for 10 min. Watching through the glass the powder melts and coats the bullets in less than 5 minutes at 400 degrees F. I pull the bullets at about 7 minutes when I see a good shine.
In fact I did batches of 500gr Lee .459's today for my 458 SOCOM. That's a lot of bulk in the oven with those big pills. I stand them up like Loads of Bacon and still water quench.
The powder from harbor freight is cheap and is hit and miss. Pay the $15-$19 bucks on Amazon and go with the good stuff. The color selection is crazy big. My favorite is a candy blue.
I'll definitely have to try your low temp method and see how it works. Thanks for thinking out of the box Elvis. Sorry for the rambling.
Elvis I dig your video's and information! KEEP ON ROCKING IT! ELVIS!!!...
hey Elvis, awesome video! you are the mad scientist of reloading! if only you could win the Nobel peace prize for this! Obama won one for doing nothing! look forward to your follow up videos on this, maybe my husband won't burn his fingers as often thanks
Kaye Szymanski ... Hey.. thanks , I like the money that comes with the prize. .. My dog took a dump this morning. . That was greater than anything Obama done... ; ) Lower temps and shorter times save the burn and power bill!
Store them in a freezer to raise the hardness?
Tried today several of your theories. First was water quenching, and then powder coating and baking at different temp and time and then water quenched again. Worked ok, checked hardness and was 13.1! That was great. The only question I have is do you clean raw Bullets after first quench with anything special before you powder coat? My coverage could have been a little thicker
So what kind of residue is in barrel after shooting Powder coated bullets?
Hey Elvis the pioneer! that's really good info and thank you for sharing it with all of us casters and powder coaters. I have some 230gr I'm gonna try this on tonight. Thanks bud. I'll let you know how they come out.
Does powder coating the bullets prevent as much leading up the barrel of the gun?
Elvis thank you for all the info. You are the one that got me started. Have you tested on the 223 yet
I never really heard you say what the bottom line is here. Are you saying that 250 at 20 minutes works best to keep that BHN up there?
Just wondering if you tried the lacquer thinner test? I was using harbor freight red baked at 300 degrees for 20 minutes, the bullets passed the smash test and looked good but I got horrible leading in glock barrels. I tried the lacquer thinner test, rubbed a bullet on a rag with lacquer and the powder coat rubbed off immediately, powder coat wasn't cured. Coated more bullets with hf red and baked at 400 for 20 minutes, passed the smash test and also the lacquer test, only a very slight hint of PINK on the rag. Loaded and shot the ones baked at 400 and no leading in any of my glock barrels. Just wondering if your powder coat is really cured at that low of a temp. The lacquer thinner test is the only way to find out if your powder coat is really cured. Look forward to hearing back from you. Thanks!!
I have mentioned this before, although with mek. I've not seen them do this, basically, they just smash with a hammer and call cured. Lol
So now the previous testing that you have done with powder coated bullets and testing for expansion..... That changes now that the bullets retain their hardness ....correct?
Makes sense, you are heating them up to the point they temper and lose the crystalized set of the lead. Sort of annealing the lead after the fact.
I need the short course on this subject but my understanding of this is we are trying to increase velocity and consistently of the bullets. What are the thin skinned varmint bullets BHN or copper? What is the max velocity of the new bullets?
Have you ever tried using a flat silicon pan and periodically shaking it or gently rocking the oven to prevent bullets from sticking?
Hey Antonio Wright.. I've heard of others trying that. It's harder than it sounds. once they start to flow it's hard to get em to move. One of our viewers even tried a rotisserie oven with a cage full of bullets slowly turning.. They turned out a mess!!! : ) But was cool to see and they get an atta boy for trying!!!
Elvis, You are a thinker. I like that. You don't say what is on your mind till there is a method to your madness. I enjoy you "leaving the bones in" approach to your channel. That alone makes people feel that they are right there in the room with you as you are discussing this and that. No flowery speech and not using words we have to look up in a dictionary. It obvious that I was never a grammar king in school, however, you don't need to be for people to understand you. So Keep up the good work Buddy, Dave.
hey thorsaxe777.. thank ya sir.. Organic here with out the added cost!!! : )
I'll second that!
And more also. there is a good thread going on in castboolits right now about adding copper to your alloy to toughen the bullet. Very cool. The method is that copper replaces zinc in the alloy. So you have to have some zinc in the lead to be able to add copper... more interesting zinc news there.
Hey Hans Pcguy, yeah been thinking about a mix like this, Didn't know there was a thread.. i'll see if I can find it. A interesting subject!
Hans Pcguy I tried the copper adding as suggested on cast boolits by using copper phosphate as a sort of flux. My pills came out pretty nice. Haven't tested hardness but they seemed harder while sizing and also noted a slight weight increase.
Do you powder coat 308s ?? 10% tin 2% silver from lead pipe with silver joints works great.
I don't have a BHN tester. I need to get one. I've only ever used range scrap lead and I've always assumed bullet lead recycled would make good bullets lol. Never had any issues so far. Wheel weights are softer I believe. What are some of the issues with using powder coated cast bullets with a BHN around 11? Does it limit how hot you can load em? I learned the first time I ever powder coated not to dump bullets fresh out of the oven on a towel. I dump em out in a pan now. Might try dumping em in water next time. Thanks for sharing your research! Awesome job!
Hey there CountryBoyPrepper! Yeah scrap range scrap is good stuff. And nothing to complain about for sure if it's working for your application! But water quenched clip on wheel weights COWWS. can far exceed them in BHN. Your usual suspect comes in at around 12- 14 BHN after water quenching range scrap. These numbers can vary a little because of the random mix. I've got cowws that have exceeded 26 BHN. This new process is a nice find to be able to mitigate (like that word) any loss where bullet hardness will benefit. More options here! I have a feeling we will learn a great deal more as others apply this method and share results. Some folks are already having way better results with the quality of PC coverage dumping them in the water. almost perfection. As with anything their are trade offs. This passes the smash test with flying colors but not the solvent test... Not even for sure if this matters? But giving you the information. I have fired soft lead with pretty good results at higher velocity with no leading. but some high pressure loads seem to like harder bullets even at lower velocities? Some folks like to mix cowws with their range scrap to increase BHN! Hope this helps a little! Thanks for being a part of the conversation!!
I like to dump them in the water even if I baked them at 400 degrees. Recently I powder coated a batch of 500 bullets in 3 batches and not a single of them had a mark from mesh tray! I use glove to knock stuck ones in to bucket of water I think it has to do with what type of powder coat paint you use, because HF red will leave marks.
Elvis, You are the man !!! great info. I hope to start casting this winter, Been collecting lead and making ingots for now, My Wilton Mini Loaf tins have made 400 plus ingots and counting.
hey terryp5001... Good deal brother... When you start you'll be prepared! The Wilton never dies! : )
Thanks for the innovative video . This info expands our range of use !
So if powder coating stops the leading why do we want them to be harder?
If you water clinch after powder coating wouldn't that be the same ?
Well Thats Just Great..... How do I explain to my wife that I need new equipment if the old stuff will work????
Thanks for the info. I guess I need to get casting again and try this method. See you at the range, and stay safe.
Hey monkeyship74401... You just have to tell the wife it's like the equivalent of a product that makes ya look ten years younger!! She'll understand! : )
did water quenching right out of the oven increase the BHN?
Elvis what method do you use to powder coat?
You went thru 10mins to tell me nothing. Exhausting.
Then get your free info somewhere else if it bothers you so
Much.
What ever you do don't say thanks dick.
Powder coating .22 bullets = dumb idea. No. Not watching this dude's video
Yes sir I’ll definitely be doing this soon enough I just have to get a set of handles for my Rcbs 150gr SWC mold
Awesome! This is an awesome contribution to the PCing community! Great work brother!(I've had plans of doing some BHN/casting/PCing videos in a couple months - this will certainly be a great addition to that.)
Loads of Bacon .. hey man! hopefully this is as good as it looks! time is either your best friend or worse enemy! I'm optimistic! so far so good! I'm working out and eating my bacon! things are looking up! ; )
I have watched this twice, and am missing the most important information somehow. I understand this is an old video, but it seems very relevant. You coat water quenched bullets, bake at 400F for 30 minutes and BHN decreases to 50%. You coat water quenched bullets, bake to ensure temp of lead is in excess of 240F but not in excess of 250F for at least 7 minutes, water cool directly from oven and BHN can be expected to be ???
I would really appreciate this information. I shoot magnum revolver loads into big animals and would LOVE to powdercoat, but I need the 20+ BHN.
Thank you
That's great news. Thanks for doing the research.
Papa's Place ..Thanks again for stopping by Pappa... !
Question if a automotive framing bolt is powder coated what would happen to that bolt (strength etc.) Over time with heat from the motor ?
I don't think the engine heat is going to be enough to hurt the tempering of the bolt over time. An engine only runs at about 200 degrees at the high end. Exhaust manifolds may reach 500-700 degrees on a average vehicle under normal operation temp. Even that shouldn't be a problem supposing your using OEM equivalent bolts. You'd have to heat those bolts to 1200-1500 maybe even 2000 degrees before you had worry about them being softened.
Elvis, why do you use tempering and annealing interchangeably I don't understand. To temper is to harden by heating a metal and dumping in water or oil, to anneal is to soften by heating it up and letting it air cool.
Hey Dima Prok.. I think people get the term mixed up because tempering is used to toughen up metal by softening it up. Its other wise brittle after hardening it. A bit confusing I know.. : ) Annealing on the other hand is similar except you usually come close to the melting temp and slowly cool to allow a workable metal.. Either way it is softening the metal, But in different ways, for different reasons. Tempering would be the correct term for this method. But The main reason I use both words is because I noticed the word being floated around alot on the subject of bullets. Wanna make sure im speaking the language everyone can understand! tomato, tomoto....! : )
The blue bullets look a lot better than the red bullets. Keep up the good work.
Great R&D. Will give it a try
Elvis, I have worked in the paint and coatings industry for many years, one company I worked for 20 years ago mainly produced thermoset acrylics and polyesters, they were purchased later by another company that also made powder coatings. there are many heat profiles available, 10 min at 350 F is pretty standard, Ok now small mass objects like a bullet takes maybe a min to get up to temp when you put it in and cools off slowly when you remove it, there is an after cure time. I want to suggest 2 things, contact a paint manufacturer and ask for a low temp cure the paint only and not the product, they make them and also look into IR cure products this heats up the paint not the substrate
Hey Mike Rupp.. I was hoping to hear from some folks that work or worked in the industry.. do you suggest a particular company to call that has a good chance of having the right stuff? Thankyou for your comment, We've made advancements in this area. And we are always improving...
Well it depends on where you are it's better to walk into a shop and see what they have on hand. Sherwin Williams is the largest paint company in the world. I worked for IVC or Indianapolis Varnish Company, they made a lot of powder, custom powder coatings, there are liquid bake enamels as well . Look in the phone book for companies applying powder coatings, stop and see them often they spray to waste and throw out what falls on the floor, ask who there supplier is also ask for low temp cure. I will do some digging and get back to you
www.powdercoatedtough.com/News/ID/188/PC-Summitry-Options-for-Low-Temperature-Cure-Powder-Coatings Read this , also look into IR cure
Could the reason the BHN dropped so much be that the lead tester is actually testing the hardness of the polymer coating rather than the lead that is under it?
Wow great news. Elvis, the powder coat jacket looks a little softer and more malleable with this method. In a very good way. Is that true? I had another idea. Heat the bullets with a quartz heater outside of an oven, that way maybe the heat will not ever penetrate very deep but still get hot enough to melt the coating.
Have cci took your idea cos they do them now ?? Just a question not a statement??
i just ordered a mold for 45 cal. black powder revolver, can powder coating be used on the bullets??? its used for hunting, will it still work in the scene that it expand !!!
