Both the .41 magnum and .44 Magnum make very good revolvers for hunting, as well as the .45 Colt. However, the .45 generally takes a handloader to get the most out of it. And .41 Magnum ammunition is not as easily found as is the .44 Magnum.
All three can be enhanced by judicious handloading, but the .44 has the widest selection of components.
Probably the biggest drawback to the .41, in my opinion is that it is not a halfway between in relation to the .357 and .44, but is too near a duplicate of the .44.
