from what I have been told by some varminteers up here, my 7mm will work fine as long as I dont hit the shoulder blade. I dont see why the 270 wont work well as long as you dont bust up the shoulders also. The bullets are smoking so hot its going to zip right through them, (much like my caribou this year), hit the shoulder blade and your liable to blow out the otherside like he was hit with a watermellon LOL (very similar to my bou last year, both shot with a 7mm and 250 grain heads). Heck go for it and report back as to your findings, I would love to get the wife out with her new 270 for yotes, now that would be an experience!
