Been playing around with one in an AR. So far so good. Only tried sierra spbt and barnes x. Have taken elk, whitetail, mulie and 1 pronghorn. Didn't like the taste of the antelope, wont be doing that again, gave the meat to a neighbor.
Ballistically doesn't seem to differ a whole lot on paper from a 25/06. Being short and fat tends to give it an edge over the /06 though on accuracy. Shoots like a lot of benchrest rounds. Worth a shot if you have an itch to try.
