Had terrible performance of 250 grain Hornady GMX out of a 375 H&H.
thats interesting, i used 250 gr GMX bullets in my 375 ruger and had phenomenal luck with that bullet. 1 big bull moose, 2 bull caribou and a very large brown bear. recovered a bullet from one frontal caribou, one neck shot quartering moose and broadside bear, all perfect expansion and performance. bear was shot multiple times.
