I normally try for double lung shots on deer and antelope. Elk are a different deal I try to place the shot to break them down on the spot. I have shot 2 bulls with the 180 NPT via the 300 Win Mag they went down on the spot.I've killed another bull and a cow with the 225 NPT in the Whelen . I didn't have near the meat loss with the 35 and 225 NPT's even with major bones broke. Moderate velocity I suspect is responsible for that. I like them both. As far as the 200 gr 30 cal, no experience but I'd bet my last dime it's even better than the 180 for everything. Magnum Man
