The brass is soft and the case head can take a beating if you don't dial your gas down enough. Nosler contracts out its brass manufacturing and whoever made the stuff for the rollout dropped the ball. Norma had historically made a lot of Nosler brass, but with RUAG seemingly buying up every nonUS based ammo manufacturer, who knows where it was made.
With the gassing, I started with my block where Odin told me they had the most success and I was getting ejector marks and even some small tears with the factory 77 gr ammo.Dialed it down and everything started coming out clean. The rebated case head is defiantly not a positive. Maybe they would have to pay royalties to Remington if they had used a necked down 6.8 case? Or Alexander if it was a necked down Grendel.? Or maybe the rebated head was to give it broader appeal. Basing off of the Grendel case would have allowed larger bullets, but then there would have been a sacrifice of velocity for smaller bullets. And I'm sure the company investing in the rollout sees a much bigger market for velocity.
I didn't think the Berger 75s would work. They are seated right at the ogive and the base sits deep, but they are laser beams out to 750. With a VG6 gamma, recoil is like a sharp 223 and sight picture barely budges.
