i recieved my arm or ally brass yesterday and it converted perfectly. ive always had great luck with arm or ally with ship times.
I also worked on some of my load development with my faxon 14.5" 6arc setup i use to night hunt. Ive been shooting the hornady black 105's all season with great luck. I chose the load on these that best matched the factory ammo (that shot great in this barrel) and loaded them to be super reliable, and are surprisingly pretty fur friendly. They have proven flat enough i can aim on fur out to 300 "ish" with a 50yd zero
Currently building a 16" setup so i can compare speeds with the same loads and help contribute to some barrel length calculations.
here is the data i landed on so far for 103g ELDX and 90g ELDX. I tried both varget and CFE with CFE providing much higher velocities. i may load a few boxes of varget just for the below zero nights we may be hunting.
1x hornady case
14.5" faxon heavy profile
mid length gas-unsuppressed
CCI BR4
1.70 O-Give (matches factory hornady black)
stone cold reliable piece in all weather conditions so far

Just a tip - the 90gr TGK is a little different profile than the ELDX and can be pushed another 100 fps faster from my 19” barrel (maybe ~80 fps faster from your 14.5”?). It can be seated farther out without getting into the lands, providing more powder capacity, and the shorter bearing surface contributes as well.
The guy who got me interested in these two bullets said he had poor results on coyotes with the TGK but also said the ELDX wasn’t any better. I haven’t used them on meat or fur yet, just long distance steel and they work great for that.
i'll definitely snag some of those once i see some available. these heavier bullets at these speeds seem to be slamming dogs no matter what as long as shot placement is decent. I think the 105g BTHP i used most of the winter had a lot of pass thru's but it was very difficult to find a hole
Shot 1k groups yesterday. The Valdada fixed made it possible/easy. Once I got dialed in at 600 I just used holds and no dialing!!!
Shot my sporter Eddystone and the CZ pistols too, it was a great day. The glass on this thing lets you see hits at 1k then listen for the ding.
At the end of the day I annealed 427 pieces of brass and I have 1k more on the way - again, goodbye 223...

1k swinger hits – AR-15 6ARC
Its been fun riding the hell out of this Poverty Pony to the land beyond 750yds. Now I have dope, ammo, equipment, and experience to shoot the AR-15 platform from 100-1000 yards with no scop...

Starting a 6ARC build, my first AR build. I’ve received the upper, lower (SLR), trigger (TT), stock (PRS Gen 3), charging handle (Radian Raptor SD-SL), and other various small parts. I did just get in my 6ARC die (SAC).
I compared the .265 bushing in SAC 6ARC die vs. the standard .265 bushing in the attached photos.
I’ve really been looking for either Lapua or Starline 6.5 Grendel brass. Maybe June will be my lucky month.
Still needing to place an order for my barrel and hand guard. Can’t decide if mine going with a 24” or an 18”? I will be using a TB Ultra 9 in 6.5 can with it. Mainly for LR shooting and possibly try it out in a 1-day PRS.
I wish I could find a hand guard with in a built in Arca rail. Otherwise I’ll need to get an Area 419 Arca to add on too.
Any recommendations on hand guards or barrels? Leaning towards a Bartlein in their 400 material.

Catalyst Arms has an Arca handguard, Geissele makes one as well if I'm not mistaken
Sgt. of Arms have the ARCA Handguards on hand: https://www.sgtofarms.com/product-page/sgt-of-arms-ar-15-17-5-arca-handguard
Shot my first 600 match yesterday. I was last against a stack of bolt guns that cost more than my daily driver. This weekend is a timed 100-1000 match that would be a great match for the rifle (all holds no dialing), but I'll most likely be teaching the 6 yr old how to shoot 22 for the first time so priorities...
I did convert another 500 Grendle cases between rounds and finished fire forming the others I had made. With the jammed fireforms at 2500 I was able to hit the 4" swingers and 6" swingers at 500 yds after the match. Rifle and bolt getting a deep cleaning now.
Shipping all my old 223 brass out today! gooooooodbye!!!!

Sounds like you are off to a great build.
I am very very happy with my Rock Creek 22”. If I do my job I get .4-.5 moa consistently.
Can’t go wrong with Bartlein either IMO. I will probably go that route with my next one for the cut rifling. Paul Craddock told me the barrel life in the 6mm ARC is about 40% more with the cut rifling over button. I decided on the RC for costs because at the time I wasn't sure (after my 224 Valkyrie experience) about the 6mm ARC - I am now. Love it.
As to length, others seem to be happy with their 18”. I reach the 1200 plate with my 22” in hand-loads (109g Berger). Haven’t tried that far with the factory 108 ELD’s. I don’t shoot suppressed.
If you are going past 1000, probably will want the extra inches.
Good Luck!
So... I got bored today and cleaned the bolt and pulled the extractor and ejector. It was pretty dirty, but the Lucas Bore cleaner worked great! Disassembled the bolt and removed the extractor and ejector.
Confirmed easy lockup with bolt you could see/feel the lugs move easily. My first time doing this with a dis-assembled bolt in an AR. So please confirm/correct my test before I go and trim all my new cases.
Dropped a freshly converted brass (NEW Starline Grendel sized to 6ARC BUT no trimming yet len is 1.515”) down the bore and tried to chamber and it would not lockup (as expected).
SAMMI Spec is 1.490” so betting it is somewhere in between.
I'm leaning toward 1.508" as a new Max trim for this chamber. What are the chances this will affect my group size or velocity? I'm thinking changes will be minimal but will run a test batch this weekend to make sure.
Thx to whoever suggested/mentioned this test - I think it was in relation to shoulder bump/chambering, but trim len seems to be closely related/testable in this situation.

- 1.513” will NOT lockup
- 1.5105” will lockup.
- 1.508” will lockup- fairly easily.

If brass grows and interferes with the front of the chamber you're basically turning the Barrel into a taper crimp die while also removing necessary clearance. You'll spike pressure and velocity pretty bad. I usually have .010 minimum from the front of the chamber for trim clearance.
Yes, I do remember this from early reloading days of 30-06. TY for that reminder. I was thinking more in terms of more neck tension but that is a good point. In terms of brass growth, it seem to me that it comes more from bumping shoulder too much as opposed to trimming brass down too much. I don't want to stray off topic so I will just trim to 1.508" - 0.010" = 1.498" and call it there. Thx!

Probably like shit, I can take them off your hands for you!
Let us know if you get speeds consistent with its advertised 2800 FPS (24” barrel)
Doing some tuning with my SA gas block and just managed this 5 shot group with the 16" faxon and box hornady black. I was afraid it was going to rain so I haven't set up the chrony yet
Finally took the new 6ARC AR out to shoot some 5 shoot groups at 100 yards with different loads. Was going to take the PPC but it was too windy so took the AR instead. I think it shot OK. Used Leverevolution from 29 to 30.3 grains and 80 grain Bart's with 0.005 jump. No pressure signs so might go higher next time.

Really nice shooting there.
Question: 80 grain Bart's - could you give us the details on this bullet???
thanks.
Thanks. It's a boattail I usually shoot with my 6BR. I bought some 108 Bergers but the freeborn on this barrel seems too short for them so I loaded the 80s.
Dominator 80 grain boattail
The 80 gr Dominator Boattail is a 7/9 double radius bullet with an .060 meplat. This bullet is the brain-child of Dean and Brett Stroud who were looking for something that would work with their 6MM...

More small piles, but with old powder.
Also just scored 3# of LeverEvolution from precision reloading...

Paul Cradock is the Man, had to start off with that. finally after having this upper since last fall I got out and fired it today. Using factory Black ammo and spending the first ten rounds to zero and adjust the SLR gas block with the tranquilo, the following ten rounds proceeded to print a nice 1.14 group at 100m. I am not one of yawl's amazing shooters and this is the first 20 rnds. thru this barrel, I am stoked.

I ordered from craddock on the 12th of January and it was delivered on May 27th.
Also after getting the barrel and seeing Paul craddocks work and attention to detail the wait was worth it. I'm running a superlative Arms rifle length piston kit and he custom made the barrel around the kit and It works flawlessly.

Has anyone tried loading the 112 Barnes Match Burners in 6mm ARC yet?
Bullet stock is getting low and I ordered some of em - can’t find much else. There is a thread on them and those posting (6 creed, BR etc) seemed to like them.

1k Match Results posted: lots of wind. I qualified very quickly in the morning. I can see the advantage of funning a semi and the holds on the scope/vs dialing also helped speedily hit targets at 600/750/1k. Scored some hits on the first round and after that went downhill. the wind was ~11 headwind most of the day at the bench, but down-range it was gusting and switching constantly.

next month is back to 600yds but there is another 1k in August.

scored a 500ct of sierra tipped game king 90's. going to do some side by side comparisons of them vs. the 90 eldx with the same data soon.
Sgt of Arms had a badass showing at a all gas gun match in march. 3 divisions and 2 of his 6mm ARCs won 2 of the divisions of over 110 shooters. both 18" tbox barreled marksman lights.
