I'm not down to one centerfire,but I am down to two calibers with multi rifles in those.I'm down to .284 and .308 calibers.These two have got me covered for all my hunting needs.Shooting bullets from 120gr to over 200grs,there is not too many animals I cannot kill with them.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
