In my experience standard cup and core bullets leave much to be desired above 2500 fps or so. After trying many different things from small to large, light to heavy, slow to fast I prefer full penetration with no fragmentation, so I use bonded bullets in anything over 2500 fps or so. I would try 150 grain speer gold dots. Best deal on the market for bonded bullets. Same basic thing as federal fusion factory ammo, which also happens to be the best deal on the market for factory hunting ammo. The expand violently but they retain nearly all their weight so they give excellent exit holes.
