im about to turn 18 and im going to buy my first deer gun. Im not sure what type of caliber to get though, i think im going to get a savage 111F. it comes in 270 Win., 30-06 Spfld., 7MM REG MAG, 300 WIN MAG. The only thing i can hunt in oklahoma as far as big game is about it whitetail. I was thinking maybe the 270. Is this a good rifle and caliber choice? thanks for any imput you can give me.
