I have both the 270 WSM and the 270 Win. I just wanted to try the Savage Accu-Trigger and a WSM so I combined the two. I got the 26 inch Heavy barreled Varmit Model. The recoil is a bit more with the WSM but if you don't have trouble with recoil with the regular 270, then the little extra of the WSM should not be a problem at all. As far as performance goes, the difference is not worth mentioning. I Plan to load the WSM to about the same velocity as the regular 270 because it has allof what it takesfor long range deer hunting.
