Bob's answer is spot on.
Right now I have four BG rifles... two 308's and two 270's. Personally I think they're equivalent on game, with the nod going to the 308 for frugality of powder consumption and barrel life, and likely to accuracy (across a wiiide sample). I also prefer SA's to LA's, so my favorite is the 308... but the 270 is a helluva a cartridge.
Either is fine for any of the game found here in Montana...
