I did a 10 shot load workup over a chronograph that was kind of inconclusive and I haven't moved on to shooting groups yet, but I went from 63-64.8 grains and the velocity ranged from 2951-3025. The higher loads had a very light ejector mark but easy bolt lift and extraction the whole way. The rifle is a Model 70 Extreme Weather w/ a 22" barrel. My main problem is getting a bullet seated without leaving an imprint on the jacket with the seater die. The load is very compressed. I polished the seater cup with 600 grit lapping compound spread over an ELD-X bullet in a drill to try to mitigate it, but it still happens. I'm going to do a ladder next week at 300+ yards with RL26 and RL17 and see where that takes me.
