If you've never shot a .260 it'll impress you. kind of a cross between the 243 and the 7mm08. it's a good gun, within it's limits. friend of mine bought his boy, about 13-or so at the time a .260, he's killed a bunch of deer with it, groundhogs too. it's a m-7, wood stock. with his 3X9 scope its a 125 yard chuck gun, 100% kill at 100. the short barrel hurts his long range shooting, and for our 100 to 125 pound deer, factory ammo is built for "big-game". the bullets, just don't open-up like they should. i don't think he's ever lost one hit, but i remember a couple that just ran like they weren't hit at all. he's loading 100grs bullets or so now?
Hammer, not sure about the WSM, i have my ffl and will check.
