I found it to be a nice cartridge ( I had a Winchester 100 Auto .243 Carbine bored out to .358"), but has factory boolits that flat pencil right through game as light as a 200lb Whitetail, requiring handloading for game smaller than Elk/Moose/Grizz, etc, IMHO.
Due to that, I actually ended up switching to the nearly ballistic equivalent .356 Winchester, in a Winchester BigBore94 Carbine.
