For 7wsm (3200 fps) or 7mm-08 (2950 fps - 24" brl), I've had good success with 140 gr NABs on deer. At 7-08 velocities (3100 fps), the 120 NBT worked great last season for my wife on a 7 pointer. I'm not sure I'd want to run them much faster than that on bigger game, but dogzapper has had no issues. YMMV.
