I had one, and sold it shortly after I bought it. Didn't like the kick, so put a muzzle brake on it, and it was too loud, especially if you have other guys close by to hear the blast.
I thought that I had a better rifle in the .300 win mag, and if you don't like the mags, I like the .270 the best.
I guess they work just like all rifles do, but it seemed to be too much for my tastes in cartridges.
