Using Shooters World Match(AA2520) in a 6.5 Grendel with 120gr Sierra Pro Hunter 22" Barrel.
28grs, 2350fps
Top Target. Bottom is a 350 Legend.
29grs, Chronograph Broke
The 29gr grouping was terrible. I stopped going up from there. No signs of over pressure just bad accuracy. I have never seen this level of change when reloading before with other calibers.
