Ripp is right! I shoot the 270gr Federal power shoks in my 375 H&H Browning A bolt(No Boss) sighted 3 inches high at 100yrds, you are good dead on out to 300yrds. I have proved that to myself in Utah with Elk, Whitetails in NY and PA, Antelope in Wyoming and plainsgame in Africa. the key is to get off the bench and practice, practice, practice in every conceivable way possible!

Good luck.
