RE: 270 Winchester Accuracy?
The only way I can say it might sound rude, but please believe me .... I am not intending it that way...
The .270 is a fine rifle round, and it is very accurate. BUT.... almost any round chambered today is more accurate than most people can shoot. I doubt that your inherent ability is more accurate than the rifle round you want, so I would suggest you buy whatever you want without worrying about the rounds accuracy ...... then practice so you can be as good as the round you are shooting. More often than not, inaccuracy lies in the shooter ....not the rifle or round.
God Bless
