Load =
Fed once fired brass
Ramshot Magnum 80.0 grains
Fed 215M primer
Loaded per Berger instructions to find the sweet spot, and the best group was 1.5" at 100 yards.
OAL = 3.455, Velocity Avg 2,861 FPS, ES = 25 FPS 2.1" group
OAL = 3.495, Vel Avg 2,886 FPS, ES = 17 FPS 1.5" group
OAL = 3.535, Vel Avg = 2.868 FPS, ES = 27 FPS, 1.5" group
So I'm wondering, should I try a quicker powder? Something like 66.5 grains of H4350?
The rest was rock solid, and the rifle is a great shooter with 180 grain loads.
What am I missing?
