Yeah 3.3 inch group at 100 yards with a scoped rifle is like the worst possible accuracy you should be hunting with. You can make a 3.5 inch group with the iron sights, so it's almost pointless to have the scope on. Try some interlocks, they're cheap and they've worked for me. The other one that people say work well are PRVI bullets. They're just cup and core, so you're looking at probably 60% retention out of a 2700fps round, but whatever it'll be dead animals.
