Thanks manny but I am going to shoot Sunday and need to start somewhere. I am actually more concerned with starting too low than too high.
I will have the chronograph set up and keep it simple with 3 shots at each level. I will also be breaking the rifle in so velocity is the main concern. If there are any signs of pressure or if velocity is close to 2800 fps then I will stop and pull the bullets. I have a collet puller and that is easy to do and I can reuse the bullets, powder and cases.
Bet the manufacturer will hem and haw or evade the question and not give you any definitive answer.
Anyway
3 @ 74
