Every time a question occurs me regarding my forays into reloading, you seem to have a video going into that very question. You are a gem and my greatest resource on reloading. I have noticed different capacity on different stamped brass, but as far as performance? Thank you for this. I don't always agree with you, but I absolutely love to hear what you have to say and love to watch your methods.
So basically your telling me I've been wasting hours of time separating my brass. Thanks. Your test groups of 10 is just right. Educating video as always.
No, I would say that it is still important to separate headstamps and work them up separately. The velocity differences between the different types of brass definitely showed that. However, I don't think brass is going to be much of a difference maker overall. More testing is coming! Stay tuned.
Ben loading both to 5.56 spec for a long time with no use but ya always keep track of your head stamps to help weed out any problems Thay may occur. Might get a batch of 223 that doesn't want to be a 556🤣👍
I'm getting good groups with the 69 grain sierra, seating at 2.235. I know that's a big jump for that bullet to the lands. My ar is a 1n8 16" barrel PSA. I'm getting 3/4 " groups with 23.5 grains of BL-C2 and winchester sr primers SSA brass. 100 yards prone with bipod.
Looks like wolf did better then the more expensive brass some people swear by the name on things so to me great test it's not about the show it's about the go if you know what I mean
Fascinating. Great test, very interesting results. I mix brass for most plinking loads but do sort for accuracy. I can see this makes a pretty significant difference. Didnt really change POI though.
This is some good information. I have more PMC brass than anything else and I load an unconventional powder for 223(IMR 4064) and the extra case capacity would be the reason I don't get the compressed loads the books tell me. This may help me as I work up a 75gr load and want to get good speeds with as little compression as possible. Thanks and you just earned a new sub!
Lapua's reputation is good as while other brands make good brass too, their brass lots differ from one to another. Lapua holds the same tight specs from one lot to another.
Lots of food for thought on this test. I recently loaded up 550 of .556 with the HB headstamp .I only tested them in my beater rifle. I have been saving this brass for over 23 years. The flash holes were awful. Just a puny ragged hole. So I had to deburr all of them. I crimp the bullet for use in semi auto not for bolt. Looking forward to what comes next.
6 years late to the party, but as a new reloader, this is something I've been wondering. Is there THAT big a difference in accuracy when reloading cheap vs premium brass. Excellent video. Very interesting results. On to part 2!
I totally get what you mean about the primer pockets. I was hand priming my first batch of 223 mixed head stamp last night with the Frankford arsenal hand primer. Some pieces it felt like a primer wasn't even seated then others felt nice and tight but smooth
This makes me feel better. Before I started saving my brass and reloading I ran through 1500 rounds of Norma brass (Norma USA Tac 223) and didn’t save my brass cause I didn’t think I would reload. As irony would have it I started saving brass when I got to my PMC and PPU ammo
I came to the same conclusion around 2015. I used Hornady, Remington, Winchester, Federal brass. The Point of Impact at 100yds really didn't change and it was not enough for me to worry about in 270 Win Caliber. Yes, fps more on some, but not enough to worry about unless I was a bench rest shooter. I still sort brass for reloading, but not really worried about that aspect anymore.
When I use berger bullets there was a huge difference from PPU brass and Winchester and Laupu brass. With Laupu and Berger bullets I had a few nods where my groups went into 1 hole. Winchester I was getting around.850 of a inch . PPU was bad across all nods and loads. 1.8 groups with Berger bullets.
back to the bullet accuracy issue, now test several same weight but different brand bullets in the same brass. given that different brands are different shapes, it would be interesting to see the differences between what your rifles like or don't like.
I would think that the velocity going up is just the gun heating up & velocity going up. my .223 coyote rifle loves the federal NATO brass for some reason.
So I had some same hed stamped brass, shot a split group (about 2 1/2 moa) with 77 gr SMK, turned out the brass was of two lots with about a 5 grain difference. Now always sort brass by headstamp, weight and firings. Your results may vary.
JMO, i think the biggest variable (and to my knowledge, unmeasurable) is neck tension. almost every piece of brass is going to have a different amount of tension to some degree. while new lots of high quality brass should minimise this to a degree, range brass is an entirely different can of worms. even several boxes of the same ammo by the same shooter could have been purchased years apart. the person who invents a way to directly measure the exact amount of neck tension will be doing the handloader community a great service.
So i am new to reloading and wanted to work up a load in my AR15 (16 inch barrel) using the 69 grain smk. I have 200 pieces of LC brass but i did not separate them by year. If I have some year mix in the same batch of LC brass, would that affect my accuracy? I am just looking to get sub MOA. Not trying to get crazy F-Class accuracy but just something better than factory for target plinking out to distance and prairie dogs.
I got the same results on my channel with pistol brass. Proved to me that brass makes very little difference at all, as long as you are shooting the same brass for actual groups. I tested everything from Lapua to Fed UMC, no real difference in any of them.
As long as the brass is the same brand with the same number of firings through it you should be fairly consistent. Once neck tension goes too far out you can see a little opening up, but nothing too crazy. Different brass just moves the nodes. Same with primers. Bullet and powder need to work with the barrel. This is the most important part.
the whole purpose of reloading is to be consistent if you're measuring volume of brass that's been fired from different guns there's no consistency it's a waste of time
Hi Johnny it would be interesting to see if you could neck size these same cases and see if there is a difference in grouping. Neck sizing vs full length
I have a 223 savage 110e that shoots a 1/2 inch group at 200 yards. These are reloads with mix head-stamp brass. If brass can be a accuracy issue, it might just affect different rifles. Thanks
Cool screen name nothing professional done. Some things done by me. Lapped the barrel crown. Trigger work . This riffle is before there Accra trigger they have today. Mostly because of hand load testing. When you find that load and bullet you really don’t want to shoot anything else. Sometimes you just get a great gun out of the box. But this gun was bought in the 1980s.
new to reloading and its interesting how many varaibles affect accuracy relating to the cartridge itself. bullet weight powder weight the primer case itself overall length. and so on.
Most of those variables don't matter with an AR rifle. One of my AR will shoot .3 to .6 MOA but I tightened it up 'almost' as good as a well bedded Rem. 700. Of course, I did much more to it as well. Then there is great control on how I apply pressure to various points like cheek-weld, grip, shoulder loading, etc. for consistency. I am sure if adrenaline was flowing it, too, would be all over the place.
LOL. Yeah (17:15) I went through this test. 1. Don't pour the water from the shells back into the clean water. You will avoid density issues from pollution. 2. I tested full-length-sized and trimmed to equal length cases. 3. Use a syringe and force water into the shell until almost full to discourage bubbles or, fill them close to the top and tap the head on the table to displace bubbles. 4. I filled each shell to "convex" and siphon off water with a piece of paper towel while looking as something reflected from the surface at 45 degrees for no distortion. It took me a long time but I had data I could use for reloading and didn't question later.
Dang your colt shoots great take that rifle to a NRA high power math if you shoot the way you are write know you would clean up the match great job sir out standing dangit
dufus I have found that blazer brass is great stuff. I tested some recently and the ES and SD was non existent. Really surprised me. Groups were great too.
As long as he measured every case from both guns it gives an average of the two and should be decent for what he was showing. If he only measured one case each, then yes it would matter as we wouldn't know which gun it came from.
From my reloading I’d say not . I’ve not seen primer holes make much if any difference I’d say neck concentricity thickness uniformity and tension burrs etc. also case volume uniformity. The reason I say this is I’ve reloaded a lot of converted berdan steel case and hand drilled my own nasty holes some so big my buddies swore it would blow primers etc etc. but nothing was ever noticed abnormal doesn’t seem to matter. Powder charge seems to me likely always most important and projectiles quality
@@jefferyboring4410 Now that I've been reloading 4 more years, I'd have to agree with you. Primer pocket and flash hole seem to matter a lot less than capacity and especially what's going on in the neck (thickness uniformity, hardness etc).
I have read in bench rest that guys use a percentage of Alcohol in the water to brake any surface tension when using that method to determine case capacity. Idk if it would have any difference in the outcome. Good Video, Dave.
Hi Johnny's Reloading Bench I've been reloading some 9mm Luger and have some 115 grain bullets I've pulled from some monarch 9mm and want to use them for my reloads but confused on what powder charge to use I'm looking at using 4.9 grains of hodgdon cfe pistol or 5.1 grains.
compare Lapua , Norma & Nosler then compare PMC , Rem. Fed , Winchester & Wolf price/capacity/performance all with Varget powder and Sierra 69gr, MK HPBT
Federal lake city all the way. Like you said it wasnt high end as far as cost but it was mid range. After that just look at performance. There really isnt any competition.
Are you crimping? Almost everyone I've spoke to has said to just use neck tension with .223/5.56 when shooting in an AR. Is there a different line of thought to this?
You should always crimp for a semi-auto. For a single loader or bolt action, no need. Without crimping, the bullet can get pushed into the case when chambering thus causing a huge pressure spike that is dangerous. There is a reason that the military requires that the 5.56 NATO be crimped.
@@matthewbeaver5026 ideally yes. Hornady the best bulk .224 55gr bullets that I have used. It's very accurate and economical. It's even better than Berrys bullets. Hornady also makes a soft point 55gr that works great but is a little bit more.
@@Nessal83 locally I can't find much Hornady my first few hundred. I've been using heavier Sierra's Tho I would like to start cranking out as much 55gr ball. As possible. Primers are just about all ate up everywhere tho.
@@matthewbeaver5026 yeah I feel you. Luckily for me, I have a stash from half a decade ago. From what I'm seeing, it's not getting better anytime soon. I don't know if you remember the run from back in 2009, but it took two years before things got back to more "normal". This time it is even worse because Russia isn't exporting primers because of covid so we have one less source.
I will never reload the bargain bin brass headstamps. Wolf, Perfecta, ect. My first experience with Perfecta, was buying 3 boxes more or less to get the brass. Probably 1 out of 5 had a centered flash hole. And I mean WAY off center.
Re-load two sets with flash hole issues (centered and way off) and compare them on the range. My guess is that you will not be able to tell a difference.
Norma tac ammo is "cheap" ammo made for the us. here in Norway, the brass of norma trainer (cheapest here) is premium, just as good as lapua. Not Even sure the tac ammo is made by norma, tac 22 is made by rws (here atleast) not sure about u guys
A most disturbing video... Been working on LT-30 light/sub 300 Blackout load, case capacity is the key. 80fps swing from minor case capacity differences is alarming. On another note, admitting your deviancy is very healthy, but I for one am more than accepting of your eccentricity Sensei.
your test sucks. You have to lock each gun in a hold fixture and bore sight it to the traget. At this point you know the barrel is inline with the bullseye. Now run the different cartridges through the test. This is a real test. The rifle have to be locked in position.......

I can not stop watching your video's.
Did you check case capacity after resizing, if so, that should make them relatively even between the two rifles..
If I were you I'd forget about the head stamp question and concentrate on twist rates vs projectile weights.

I would’ve like to have seen the concentricity differences between those loaded rounds from one brass to the next.
How would you rate ppu brass .223 I have weighed some and some hornandy and ppu is heavier and is slightly thicker
Do you have a video with starline 223 or 5.56 testing?
I would think that the velocity going up is just the gun heating up & velocity going up.
my .223 coyote rifle loves the federal NATO brass for some reason.
JRB have you considered concentricity? Those 70gr GMX are awful long bullets.

I just separate by LC and nonLC. Reason being, I sometimes trim the LC to 300blk. I treat all LC as 556 and all non LC as 223 regardless of the stamp.

Makes sense - with lower (smaller) case capacity, you'd expect higher pressure resulting in higher V.
I have a question please... in the same batch lake city brass 556 trimming length 1,750/1,749/1,749,5. Does it affect accuracy?
Norma and Hornaday 223 no crimp primers did I hear you correctly? Any other brands?
As soon as you said pmc brass, without watching the rest, let me guess, offset and inconsistent flash holes?
Jonny if you want solid copper bullets to group you must seat them at least 50 thousandths off your lands ,,some guns can get by with 30 or 40
Is that colt a 223 barrel? Just wondering what your thoughts are on shooting 556 in a 223 barrel

Norma is good stuff, but IMO Lapua has overshadowed it.
However, I use Hornady as the best compromise between cost and quality.
When testing capacity with water, put just a touch of soap in there and surface tension is gone.
How do we know that it's actually you who is talking?
How long are you waiting between each shot? The sunlight really shifts when you were shooting the psa.
Your tighest groups were the PSA & Wolf Brass, fellow by the Colt & Federal Brass, and the Colt & Wolf Brass.
