I'd be happy with the 80's going over 2700fps. Right now the 75's are loaded with 23.5 grains of H4895 and good accuracy which is where I stopped with those.

I had a RAR puncturing primers shooting 4895, and then CFE. I switched from std primers to mag primers with a thicker cup, namely from CCI 400 to 450. 205m also have a thicker cup, as do Rem 7.5. The goal was to run them closer to 5.56 pressure. Getting 2950+ with 75 Amax.
