There was a thread about 9-10 months ago on WSM wildcats, primarily the larger calibers. Murphy said he had done all the calibers up to .416 and was then currently working on a .411 version he called the 410 Warthog.
Murphy, I've got a couple of questions for you:
• did you ever finish that workup, and if so, do you have a reamer and dies made up?
• did you lengthen the neck on the Warthog, or on another .375 or larger WSM wildcat?
I think the WSM case with a caliber length neck would still be between the Ackley/Hawk wildcats and the Taylor versions for case capacity and power, which is plenty for North American hunting. I would much prefer a beltless case with plenty of shoulder and neck, than one with an extra 100 fps. Plus, I like the idea of having .411 hardcast gas-checked pistol bullets for lower cost practice shooting and deer hunting.
