This one is 1 1/16 - 16. I have other videos with metric and even square threads. Not much different or more difficult, just different. Thanks for watching and for engaging the channel!

That's a great tip! I do use the drywall tape on most things, but I'll have to try your copper pipe method! Thank you for watching and engaging the channel!

Thanks for watching and for engaging the channel!

I hear you on that! I’ve found that’s a good way to avoid galling on the threads, too.

thank you for watching and for the suggestions! FWIW - I do use brass shims between the jaws/barrel. I guess it's just the machinist trained side of me thinking choking up on the barrel is best for rigidity, but you do have very valid points! Others have mentioned similar things. While I don't torque down super tight, ID deformation is a definite possibility and I'll take that into consideration moving forward! Always open to constructive suggestions/criticism. Thank you again!! (BTW - I love your channel!! Subscribed!)

hmmmm.... that's a good suggestion. Perhaps that's what the odd size is, never thought of that!

depends on the cartridge. Bigger/longer cartridges take more time due to more material being removed. It takes as long as it takes. No rush. Thanks for watching and for engaging the channel!

don't do it! otherwise you'll be sending it to us to get a liner installed! 😁

it is a great underappreciated cartridge for sure!

Carbon Fiber barrels can have some consistency issues. They look snazzy and are nice and light weight, but I would personally go with traditional steel.

@@AccurateRiflesandRestorations Thanks for the quick reply. I think you are correct. Love to watch your builds !

Me too

Video was shot and rifle was delivered way back in February. Since then, it has been winning matches and shoots very well from what I heard from the customer and a few others. New videos will have more accuracy proving in the future, I promise!

@@AccurateRiflesandRestorations Thank you I love to watch people testing accurate rifle.

@@MMBRM Try taking .750" off a Carbon Six or Proof barrel and then thread to 5/8-24 thread. Today's lapping by all "best" barrel makers does not require that dimensional take off unless you're trying to achieve a reduced barrel length.

@@johnseptien3138 Neither one of the scenarios you presented are taking place in this video. 0.750" just gives you some margin of safety. You can normally get away with 0.5". All the carbon barrels I've seen come with 2" or so of steel at the muzzle when you buy a blank. Which is plenty to cut off 0.5" and thread. You're wrong about most good barrels not requiring or recommending that you cut off that much from the muzzle. There's a reason that every steel barrel ships at least an inch longer than finished length when you order blanks. You think they wouldn't save every inch of steel they could to cut costs if it didn't matter?

Thank you very much for watching and for engaging the channel! Bartlein does say there is no need to cut off any additional length from the muzzle end of their barrels anymore. They've been manufacturing their barrels long, cutting off the buggered section, and shipping the final length. Still good to cut a fresh crown in any case. Others are following suit, but it is always wise to call and ask, as well as borescoping. I do explain that I borescoped this barrel (but did not get footage of it) and that the bore looked good, but I was cutting off the 1/4" or so just to be on the "safe" side. The rifle shoots "lights out" and has won some matches this season, so there's definitely no issue with this particular barrel. Very good advice none-the-less!

​@@AccurateRiflesandRestorations ​ Thanks for the reply. I have heard anecdotally that some manufacturers cut off the distorted section but haven't seen it myself. Do you know when Bartlein started doing this? I ask because the last three F-CLASS barrels I did were Bartlein and they all came in over a inch longer than their finished size. Including one I did less than a month ago(Although I don't know when they actually were made). I think I still have the cut off portions of them hanging around so I'll chuck them in the lathe to see if they still have the distortion in them. Often times you can't see it with a bore scope as the wear can be very minimal(lands can be up to 0.0005" shorter or less sometimes). You can always check this by using a tenths indicator probe inside the bore near the entrance to the muzzle measure the land and groove to get the height of each land and then compare to a spot further in(easier if it's dialed in concentric). Glad to hear that the barrel is a shooter! That's always very satisfying. My three bartleins just came first, second and third in a mid sized FTR championship. One shot 7 out of 10 matches clean while averaging over 50% X count. The conditions made for easy shooting but it still makes me proud! Mild conditions make the accuracy more important. I wish your videos had been around when I started out. They would have been a big help. I'm sure they can still teach me a thing or two. Take it easy.

This was filmed in Feb in Wyoming.

Keep in mind I've sat in a 4th of July parade in Afton in spitting snow and rain. Welcome to Wyoming!

Thank you for watching and for the comments! For a basic barrel (SAAMI chamber, standard length, contour, no muzzle threads, plain barrel) with no other options it is slightly cheaper. These prefits are machined with looser tolerances in order for them to fit any/all actions, so depends on if you care about that, or want someone like me to properly fit the barrel to your specific action and be hands-on the entire time - rather than some CNC robot mass producing barrels for the masses. In theory, accuracy could suffer with a prefit due to this, but I have heard lots of people are happy with their robot-made prefit barrels. Also be aware that you need to invest in expensive gauges, vises, and wrenches to properly torque these barrels so they don't come loose and headspace is correct.

Thanks for the visit

Thanks 👍I appreciate you watching and for the nice comment!

Sorry about that music (everyone), I was a bit biased because it was a friends' band. Won't use it again!

what's the correct approach to reduce deformation while workholding?

@HiRayWilliamJohnson I don't think reducing is an option. from what I've tried and seen, your two options are to live with it or eliminate it. The only way to eliminate it is to use the true bore alignment system or the B.B.A.R. collet chuck.

That customer is quite happy with it, and has successfully harvested some Antelope this year. I'm actually working on a new build video (307/Shilen/HS Precision/Leupold/Hornady) that will feature some grouping tests on paper! stay tuned!

@@AccurateRiflesandRestorations Awesome! I'm looking forward to it.

Glad you enjoyed it

Cool. Send me one and I'll install it! 😁

@@AccurateRiflesandRestorations the time you will save will pay for it very fast. I went with the cheaper magnetic strip unit and was under 500 bucks.

Hey John! I just developed them over the years to suit my needs. Simple stuff. Brownells has a good starting point in their documents section...

oh man, I was waiting for this one!! It's admittedly "lazy" but we're just cutting wood here. If we were machining important metal of some sort we would definitely use a proper collet. Thank you for your concern, but we have never had an issue doing it this way for years. Thanks also for watching and for engaging the channel!!

Let us know if we can help you out with that next one! Thanks for watching and for engaging the channel!!

23:00 - it takes a "standard" 1 1/16 -16 (Remington 700) threaded barrel, if you really want a yucky prefit... 🙃

agreed! ...Defiance are pretty over priced IMHO. Nice actions, but still, a lot of similar/better options for less $$$$

Appreciate the support, brother!!

Ah yes, that is probably exactly it! Forgot they offer a 3-pos safety. Thanks for watching mate! Cheers!

Maybe you should start your own RUclips channel

@@pitts3219 I bought the video cameras then I haven't a clue how to make the videos. With the sales of the AR 10 and AR 15 uppers now gaining sooner or later I need to get this done on videos of what I build in video's. I am sure many gun nuts would like to see the AR 15 upper I build in 7.92x33 Kurz or 17 Remington fired and the AR 10 uppers I build and sell in all of the WSM magnums - 6.8 Western - 6.5 PRC /- 6mm-284 win /- 6.5 -284 Norma /--- 250 Savage and 358 WSM and a 375-300 WSM . One of my own AR 10 uppers I hunt with is in 375-300 WSM and to show gun nuts this AR shooting would really get peoples brain gears turning what they could do with an AR in 375-300 WSM. I just got the new Pac Nor super match barrels 2 days ago to do another AR 15 upper in 7.92x33 Kurz - one 6 mm barrel to do an AR 10 upper in 6mm-284 win - one 25 cal barrel to do another AR 10 upper in 250 Savage and a 30 cal barrel to do another AR 10 upper in 300 WSM all will be for sale soon. In 25 cal and 30 cal I ordered the Polygonal rifling to try something different. Another of my own AR 10 is in 6mm-284 win and that is really amazing shooter out doing even the 240 Weatherby mag. The AR 10 cycles the 6mm-284 win like the AR 10 was designed for the 6mm-284 win. Once the adjustable gas block is adjusted for proper operating pressure the AR 10 cycles the cartridges like a champ ! packs of running coyotes don't stand a chance in hell against this auto loading 6mm-284 because 70 grain 6mm bullets are leaving the barrel at 4200 FPS.

@@pitts3219 If someone is in the Pacific NW and has a new business or starting a business related to outdoors or hunting and that person has skills to make videos, I will make a deal with them if they make my videos then when I go to trade shows to sell my AR rifle uppers this person can use part of my booth to promote their business. I need videos or my AR uppers being used in hunting trips as a promotion video's. These booths can cost $300 to $700 or much more like the Alaskan great outdoor show I attend is now $1200 so this could be a good trade

that's a good tip! I do do this when internal threading actions. Will give it a try someday. Thanks for watching and for the comment, mate!

Glad you liked it!
