I bought this with the idea of running strong 45 LC & watered down 454 Casull threw it, same as the Alaskan. I have a bunch of Starline 45 LC brass and a couple boxes of the Winchester 454 factory ammo (silver box w/ XTP's), to start with. Honestly, I admire those of you who hunt Alaska & Africa for the really big dangerous critters but don't think I will be able to acomplish either. The .45 LC is probally all I will ever need for my stomping grounds.
