I think I have shot about a half-dozen with the .44 using everything from 240 SWC's through 300 XTP's. If I were going to pick, I'd use a good SWC or Sierra's plain-jane 240 JHP, goosed to 1200 fps or better, and I'd try and nail the spine at the shoulder. Penetration in the right spot beats expansion in the wrong spot, ever time.
