I believe it all depends on the person and there ability to hit where they are aming.all cal. mentioned will do the job out to 3oo yards and beyond in the right hands.
thats why there are all cal. and name brands. noteveryone likes the same. and thats the way it should be.
ifnot then there would be the damdest fight you ever saw. we would all want the samewoman and gun to fight for her with.
I love my 243 and will stick with it till death do us part.I can hit what I shoot at out to 200 yards, beyond that I may could do it , but wait and watch him till later.maybe closer in a day or two. the old eyes and hands just don't hold still like the once did.
good luck to you all , no ,matter what cal. you pick.
