260 or 7-08? easy question. Guns are relatively inexpensive and your money isn't worth chit, buy both or the extra will get wasted on rubberdogshit made in China available at Wallyworld. Either one can fail so you also need the other as a backup. Gas is the expensive part, so be a Boyscout and "be prepared". I went the 7x57 and 6.5x55 route myself. Load all your ammo too or forever beheld hostage to politics and marketing dickheads. Any other questions?
