Great thread,I've enjoyed the different perspectives. I've had my M70 XTR since 1981.Shot a few 250's in it but the recoil was pretty rough, so I started shooting some loads with 200 gr Horn SP's and 200 Speers. Loaded to 2900+ they are hard on the deer I've shot with them so now I only load them to 2700-2800fps. Still kill the deer just fine. I've stashed some 250's and some old 275 gr Speer's in case I need to use the heavy bullets. You guys from the north country atleast get to use your 338's for what they were designed for, can't imagine using one for pronghorns. Magnum Man
