Need expertise on what would be the higest weight bullet I could use in a 1-12 twist? would 80 grain bullet weight stabilize? I have some loaded to try today they are berger 68 grain bullets, and the recomended powder. I can't think of what it is here at the computer. I am trying different bullets 65 V-Max, 75 V-max 70 grain Sierra hp. I am looking to achive a varmit target load with the best wind bucking w/o suffering accuracy. trying to get some expertise on the best bullet and powder w/o shooting everything to find an exceptional load. The rifle is a Savage 12 target varmit rifle black composite stock right bolt left port single shot. New to all this at 72 am trying new tricks. Never had a need for such till I bumped onto this sight. Thanks Lou
