A 240 grain SWC at 900 fps from a .44 SPL or .44 MAG will penetrate and break bone. I load my S&W 329PD at 900 fps in .44 MAG brass 'cause I don't like to shoot .44 SPL in my .44 MAG revolvers and because the recoil of full power .44 MAG. ammo in that light revolver is sharper than I prefer. Mackay's 240 grain SWC shoots good groups in my Rossi 720, S&W 624, and Taurus 44l.
