Have shot most all a 30 Cal. will leave the best blood trail.berger bullets seem to be working well for me. After losing several deer I found a deal on a a custom 300 rum seems to drop them in there tracks. Even seems to be forgiving if you make an poorly placed shot. A lot of overkill since finding the Berger's I'm going to down size try some berger 180 vld's in your 7 mag. If you don't reload you can buy some ham ammo.
