I only handload so have never investigated the fusion bullet.

I load 120 BTs going 3100ish... hard, small, fast bullets are dramatic on elk. I've loaded 140 TSXs going 2850 but it's never taken elk, but my 06 shooting 165 TSX went stem to stern through an elk at 2800 and the 140 should also. 120 TSX going 3100 should be dramatic also.
