HI guys, I'm building my father and I matching 6.5x284 hunting rifles on savage 110 actions. Where do you guys draw the line on to thin of a barrel? My 6-06 has a med palma from pac-nor and as much as I love the rifle it's a little heavy for a pack around deer rifle. I don't mind the weight to much, but my father might. I called nss and they said a 28" varmint barrel will measure .720 and a 26" is .815. Should I go down to a magnum contour or will I be giving up to much steel?
