Trying to figure out what is the best load for my 7mm RemMag. I am using 162gr Hornady SST. I have been loading with IMR4831 and RL25. Both seem to group close to the same. I have recently been using the RL25 more and have been adding more poweder. The book says max is 69.3gr. I have moved up to 68.8gr but a couple were actually 69gr according to my RCBS digital powder dispenser. Looking at the primer after it has been shot, I do not see any signs of too much powder. Should I go up more? What other signs of too much powder should I look for?
