I shoot the 250 grain Barnes Expanders and their accuracy is exceptional. I can load anywhere from 80 grains of FFFg to 100 grains of FFFg. All it does is raise the level of impact but nothing right or left goes out. I shoot 80 grains because for the distances I am shooting that is all that I should need. Now if the deer would just come out in the day light and let me test my theory.....
