I have a .44 magnum pistol pac, a .414 SuperMag, and a .445 SuperMag. More recently I purchased a compensated barrel for the 445, but haven't spent the $$ for the wrench (I keep telling myself I can make one). Hunted with the .44 and brought home a couple does (over a hundred yards for each, and you're as surprised as I was!). I've not had an opportunity to hunt with the other two, only punched some paper.
