IF you're talking about factory ammunition then I think there is only 140 gr. available. I chronied some 140 gr. loads from winchester and they were puttin along at about 3010 fps out of 2 foot barrel. This is definitly a reloader's cartridge.
No doubt you can do just about all your hunting with a 264. Load up some 95 gr. For coyote and 140 - 160 gr. for moose. The 130 gr. Barnes tsx is a good one, still playing around with that one but its coming with me this weekend for whitetails.
