It does in the lighter bullets (200gr.), but the Whelen has the edge with 225gr and 250gr bullets, due to throat length and the ability to seat bullets out farther. But if you really want to slam something from a 30-06 parent case, check out the Hawk and Hawk-Scovill cartridges. They take the '06 and move the shoulder forward, keeping the same taper/shoulder angle and get about 10% more capacity. It makes the .358 skate along at about the .375 H&H's class. You fireform brass about the same way you do a Brown-Whelen. TopHat used to make model 1895 leveraction rifles for these wildcats. The .375 Hawk is a good dangerous game rifle. In a leveraction that will shoot Spitzer bullets, it should be awesome. However, I'm pretty happy with 250gr. Speers at 2675fps and 3950 ftlbs or so. That's what my Speers chronograph at with RL 15. I get back from Afghanistan this Fall, and intend to use this load on elk in Colorado.
