I purchased 100 300WM Mag cases from ADG about six months ago. I find it to be very consistent and very well annealed. About 1.5 grains less capacity then Winchester.

Just a short follow up on the Peterson brass. I shot 20 rounds with 74.5 gr RL26 with Hammer Hunter 196 so stout load. When I measured brass headpsace, it was exactly the same as previous fired brass and only increased 0.002 in length. I just FL sized back the 0.002 so it is back where I started with new. The length was exactly 2.62 and no changes whatsoever. I re-primed with Fed215 and the fit was as snug as new. Time will tell but the Long version appears to be doing exactly what is hoped. I expect to get quite a few more loads per piece than before with this brass. Very pleased so far.

I shot 3 loads of H1000 at Nosler 180 Accubond recommended accuracy load of 79 gr of H1000 and three at 79.3 . The 79 gr load was 9 ES and 4.6 SD on virgin brass.
Best Ihave gotten so far, been using Winchester, I now have some Winchester brass for sale 😂
BTW, the 79.3 showed no pressure, but was much more noticeable recoil than even 80.2 grains with CCI 250 and Win brass.
Cases didn’t change at all, but only measure.0005 under my original headspace anyway.
Very pleased 😀

Jud: Thanks for reply, I pulled trigger on some few moments ago since all I have is some RP brass that primer pockets are not holding up at all, lots of it but still wanted better life span. Once I get it, I will post up comparable result testing from my other brass to it. It sure llooks pretty good and if annealling is as good as it looks that is a huge benefit to me.
I believe it is excellent

Mine came today. Kudos to Graf & Sons for their packaging. The two full ammo boxes were placed in a box-in a box- in a box, kinda like Nesting Dolls. I'll get around to inspection measurements this week, but they all do seem to have been annealed properly and have proper flash holes without burrs. And of course no dented necks !!!!
When compared with other new brands SIG, AMMO Inc, GFL, Nosler, JAG, Barnes, Rem, Win, one can definitely see the difference in length to shoulder.
And quality
