Back to the Rifle. The T3 is adequate for the ranges to specify. I always used heavy bullets, 175gr for long distance. I have stepped back and have started using 129, 140 and 160gr. The Newer bullet designs in the 140, 150, and 160gr class carry more velocity and energy, considerably more than the older 170..175gr at distances to 500 yards. I started loading Barnes 160gr XFB, but have made the move to 140gr XFB. I have enough of both to last me the rest of my life for thick game hunting. Be careful of Ballistic tips. I hit a whitetail at 200 yards and the bullet blew up on a rib. My second shot was in the neck. I never had one get up before that.
