Ive got around 300-400 of the Expanders and Spitfires and have shot them since the first came out. Out of my smokeless Savage @ 2400 fps they put the smack down on deer. I sometimes use the Spitfires when I plan on hunting a spot that might have a long shot because the Spitfires have a better BC than the Expanders. Never have to worry about a Barnes bullet fragging out like a jacketed bullet will. h.h.
