I am at the stage where I have so many different bullets around, I am re-testing all over again. I have decided that once I shoot them up, I will go over my notes and purchase only the bullets that the rifles like the best. So far it is pretty consistant. XTP's, Nosler, Shockwaves, maxiball, roundball, large monster conicals, and Buffalo SSB's. Then come the powerbelts, and sabertooth conicals plus all my home made bullets.
