I just got back from the range and capped off 4 boxes of this stuff. Man, it's nice to shoot a round with some authority after all of the .223 I've been shooting lately! Even the wife enjoyed the increased power level. Anyway, this stuff is very accurate in all of my bolt guns. The Weatherby was the best, constantly grouping under 1" at 100 yards. The Ruger Mark II Stainless didn't like it much, but I expected that. That gun complains about most everything it's fed. The Browning A-Bolt Medallion Grade came in a close second, with only 2 of the 5, shot groups opening up to just under 2". I'll be buying more of this stuff, as it's excellent ammo, and loaded stiff. I had zero extraction or ejection problems with it. Makes the .223 feel like a woman's varminter! Bill T.
