The entire WSM family has fallen to the high BC heavy for caliber bullet technology. SA magnums in .30 and .33 caliber utilizing + or - 1.7” projectiles are not feasible on 2.1” brass and 2.86” SAMMI or WSM Wildcat cartridges. Even with a 3” magazine you would be hard pressed to stay in a 3.2” COAL with these .725+ BC projectiles. That doesn’t mean that the WSM family of cartridges aren’t great hunting cartridges, they are. They’re just not suited for fast twist heavy for caliber use as is currently the trend, especially in heavy, long .284”, .308” and .338” magnum caliber use. A 325 WSM is a potent big game cartridge, but it has no bullet technology in the high BC arena and is even limited in standard bullet design. Because of this it is absolutely on the dead end slide. In the end the 300 WSM will be about the only survivor. There’s a reason the 284 Win and 6.5x284 Norma in long range comp need 3.2” room to perform at their highest velocity levels, no difference than what a WSM needs. In doing so you somewhat defeat the whole purpose of a SA design, which was the WSM goal all along.
