[QUOTE="ss8541, post: 6604, member: 104"] Finris, I was just looking at my notes on the pressure loads that I fired with the 173 HV. They read something like this. N560@89.7 grains, 3417 fps (No pressure signs)could try 91 and 92 grains. N165@90.5 grains, 3410 fps (ejector marks, MAX LOAD) need to drop 1 grain. RL22@92 grains, 3541 fps (Max Load, light ejector marks) RL25@97 grains, 3575 fps (est max working load)drop to 96.5 shoot groups. Ramshot Big boy@99.5 grains, 3540 fps (est. max working load) I was using Federal 215M primers for this test. It was conducted in 55 to 70 degree F temps, at 480 ASL. I shot the load with RL25@96.5 grains using Rem 9.5 primers and velocity dropped to 3480 fps. THIS SHOULD GIVE YOU A RUFF IDEA OF WHAT TO EXPECT. You should have an extra 5 or 6 grains of case capacity to work with and this may help. Vince [/QUOTE]
