This year I was fortunate enough to finally able to harvest a bull with my muzzleloader and in turn see what the equipment and specifically what the Speer Deep Curl .452 300 grain pill was capable of. The shot was somewhere between 100-110 yards quarting to. Bullet impacting forward in his left shoulder and coming to a rest just under the hide center shoulder on the opposite side the elk ran approximately 50 yards after being hit stood there for a minute and collapsed/died. Didn't find any blood on the ground but didn't really look either. Bullet expanded beautifully and performed very well as far as I'm concerned.
