I'd consider trying out a box of the Federal Premium Vital-Shok loaded with the Barnes Triple Shock X-bullet (TSX). For deer I'd probably choose the 140gr version, but they also load the 160gr TSX for 7mm Mag as well. The TSX will expand quickly and will penetrate extremely well (I doubt that you'll ever have one NOT go all the way through a deer), but won't fragment and shouldn't create the mess the ballistic tips make at magnum velocities. I've had good results accuracy wise with the TSX, but haven't yet used them on game (yet) so my suggestion is based on educated speculation, not hard empirical experience, but the TSX has a good reputation for taking down game.

I guess it really depends on what you mean when you say they "...tear the animals from stem to stern inside..." Are you talking about causeing edible meat damage, or just blending their innards? If the latter, I'd say stick with the bullet you know your rifle shoots well and gives you dead-right-there performance. When you liquify their insides, deer don't go far.
