RE: .44 Rem Mag
I would suggest handloading for it. If your getting into handguns with a "heck, why not? sounds fun and challenging" than not only will it be a rewarding addition to the whole experience, but you can get hunting, target, plinking, rounds all from the same brass. You can also get exactly what you want out of the round (read: hotter hunting and milder plinking rounds than you could from factory).
