Winchester’s .300 WSM: Short And Fat Versus Long and Slim
When we compared this new round, and the rifle for which it is chambered, to existing í06s and .300 Winchester Magnums, we were left wondering: Whatís the point?
Winchester’s .300 WSM seems a bit strange to us. Its purpose would seem to be the achieving of a somewhat lighter rifle while maintaining the approximate performance of the .300 Winchester Magnum. With its 1/2-inch-shorter cartridge length, the .300 WSM’s action can be half an inch shorter, too. Also, there’s the matter of a shorter bolt throw, which implies a faster-operated rifle. Independent tests of these points by some friends of Gun Tests indicated they are not necessarily true. (They found identical rifle weights and bolt-operation times in a casual test of on-hand rifles.)
