Thanks Rodger, I think my shootin' partners thinking was varmint and defense oriented with the 125 gr. Sierra. Worst case scenario, I would have used data for the 130 gr. SPEER from their manual and now I don't have to! I'm surprised that My Lyman 46 doesn't have a load for the 125 Sierra, guess it wasn't around then, I can't remember that far back. I do agree that Sierra seems to be a little different as far as ballistics and I have never bothered buying their load manual. Will be loading up and heading for the range tomorrow!
