Dean I would guess that its deer, antelope or possibly elk. The antelope/deer season opens 10/1 in Wyoming and I'll be there with a couple of new rifles. I can't speak to the opening date for Montana but that's my guess.
Bruce this Michigander is getting his sporting rifles in good order....you know just incase were invaded by Democrats

. The list so far Win M1894 38-55, Win M71 348, Ruger #1 450-400 N.E., Heym .500 B.P.E. and to many pre64 M70's to list. Be prepared I say. Off to the range to tweak the new 25-06. Good hunting to all.
