slug ballistics. The 20 ga is 330 grs at1200-1300 fps. Put a 330 gr bullet in a 6" barreled .44 mag, and it won't crack 1200 fps, I promise you. So, no, the .44 mag is NOT a "stopper" of bears or cape buffalo, with body shots. So it is a VERY poor choice of handgun,even if you DO live on the Zambesi River.
