I run my orgin with accumag wsm, and standard 308 mags with feed lip adjusted. Both feed perfectly. I actually don't think I had miss feed since mags were tuned. Which didn't take a lot
Got my 7 SAUM DTA barrel back last week. It's a 8.3 twist 24" Hawk Hill with a long throat (.200 I believe). I only have 190gr Atips and H1000 at the moment.
190gr Atip
Hornady 6.5 SAUM brass necked up
H1000
Fed 210m
Loaded .020" off the lands
Hit my pressure at 63grs/2755fps with mild ejector swipes but no other signs so it maybe the brass. I'm going to do more load development once I get some 190gr Berger LRHTs to try.

Anyone compared the adg brass to Norma? Got a 7 saum SA build in the works and need to start component shopping.
Roger that I’ll do some hunting. Got ten or so weeks waiting on my alpine hunter anyways.
Oh hell. Only place I’ve seen that’ll let you back order is creedmoor sports and who know how far out they are.
So being tougher to get certain powders what are you guys thought on running IMR 4831 pushing 190gr Berger Hybrids on a 27" 1.8T Barrel. I know the slower burning powders like H1000 and RL26 are most guys choice but I found about 55lbs of IMR 4831 for a decent price debating on buying a chunk. Hodgdon's chart would only go to 175gr bullets but looks like you could run less powder, with a little less pressure, and about the same speeds.
IMR 4831 is kinda between H4350 and H4831, both of which are way to fast for 190’s in my opinion. Out of a 22” barrel I’m running 175 Berger’s at 2800 with h4350, and 180 Berger’s at 2760 with h4831sc. And that’s about 50 FPS from stiff bolt lift on both loads.
If you’re stuck on the 190’s, I’d say wait till you can find H1000 or RL26, they pop up from time to time. Otherwise you could pick a lighter bullet and run the imr 4831. Just my .02

Fella was running 55 grains h4350 with 190 bergers an said rifle shot more consistent with it then h1000. Personally im running h1000 or rl26. Just case fill is what id worry about with the faster powders
Its not as good as h1000. I have noticed rl26 specially when u shoot strings and leave a round in the chamber tad to long itl jump in velocity im my findings or on hot days. Speed sure is sweet tho. Running 190s in a 32 inch. Been using h1000 lately do to alot more stable
I just have quite a bit of IMR 4350, picked up some more IMR 4831, and have 1000 Berger 190 Hybrids but cant hardly find any H1000. Might just use the powders for other bullets and wait till I find some slower powder for the 190's
Has anyone tracked a new barrel to see how many rounds it takes for the barrel to speed up and stabilize?
I'm at 14 reload cycles on my ADG and primer pockets are starting to open up. Likely won't get more than a couple more cycles out of them, but no complaints. I run a fairly stout load just short of heavy bolt lift/ejector swipe.
That’s good to know, I’ve gotta make 50 brass last through hunting season if I can’t get more the next run
Adg 7 saum should start shipping to merchants soon. Got an email from adg yesterday.
I wouldn't hold your breath for ADG brass I've been waiting forever and seen lots of guys waiting for well over 6 months. Personally I've been buying Norma / Nosler anytime I can find it where I realize that ADG is prob the best If I cant buy it then it being the best really doesn't matter...I sure hope so! I have a brand new build and no brass
I scored some IMR 4955 and was wondering if anyone has data for this in 7saum? I've found some data for it for 7 mag, was going to drop a grain from their min load and build up from that sending Berger 168gr VLDH.
Drop down a grain from 7 mag minimum? Or 7 saum minimum. The burn rate chart put imr 4599 between rl-26 and 4350. Dont know anything about this powder, but if your going a grain below 7 mag charge wieght, might be a problem in the saum
I ran 57gr of 4955. My notes say, Heavy bolt lift "reduce charge and reduce CBTO". No speeds.
162 ELDX new Nosler 300 SAUM brass CCI 200. I did not try it in ADG or Gunwerks brass I moved on to other powders.

Got everything else just waiting on my Magnum Bolt to be made from BAT Machine and I can get everything to the gunsmith and get this thing swapped over from 260REM to 7 SAUM. Loaded up some dummy rds with Berger 190gr Hybrids loaded out long starting to get antsy in the pantsy over here...
Only 2 left, thanks for the heads up!

Using rl26 in a short action what speed should I expect running a 175 elite hunter and 180 hybrid for occasional target steel.
haven’t decided between a 22 or 24 in barrel. It would be a proof sendero and would wear a can.
thanks.

When I was shooting 180 eldm's with rl-26 out of a 24" barrel I was getting 2860 fps
