Not sure where you' re from Coach, but one thing to consider is that most non-resident elk tags cost anywhere from $450 to $750. It would be a shame to come home with that tag in your pocket because you limited yourself with a gun that' ll only shoot accurately about as far as you can throw a baseball. Granted that it' ll probably kill ' em if you can get that shot, but hunting out west more often than not offers up shots that are 150 yds +.
My recommendation would be to buy, beg, borrow or steal yourself an elk gun in .270 or bigger.
Don' t forget to get your hands on that shooter in time to practice with it!!!!

Good luck!
