re: Help with new rifle caliber

Of those 3 options you have us, I would go with the .308. You already have a 7mm, and the .270WSM is basically a ballistic clone of that in a short action. The .270 is awesome with 130grain Barnes TSX (at least ours is).

But, there is just something magical about a 168 grain bullet in .308. Great round.

Btw, excellent choice of rifle/glass combo. Any of the 3 you choose should perform wonderfully out of that rig.
