Wanted to update this- was having chrono issues with my previous loads. I'm now getting 2825 FPS with 56.6 grains from my 24" Model 70 Supergrade, so going to try moving up some. No pressure signs as of yet. Copied the factory stuff's COAL as it shot well in my rifle, just varying charge weight now. Have a ladder up to 57.5 grains loaded for my next range.
