So I've been doing some load developing with a 5r milspec 308, hornady 178 hpbt, lapua Palma brass, imr 4064, and small gold metal match primers. First groups were shot at a coal of 2.830. All loads from 40 to 44 grains were around 5-6 inch groups at 385. Second test groups were shot exactly the same except a coal of 2.805. All groups were 5-6 inches until 43.4 43.7 44.0 So my question is now should I play more with seating depth?, or what could one do to tighten up the 43.7 group. The 43.7 group measures 2.1 inches.
