Lots of friends and experts have wisely commented in this thread, but I'm with my bud Ala Dan and the .41 magnum (from a top-quality revolver, with a minimum five-inch barrel, and firing the type of load Jim and Sam endorse). My concern with the .44 mag is the second shot; I am able to reacquire the target far faster with a .357 or a .41 mag, than with a .44 magnum. Earlier posters have astutely commented that a second shot with a wild boar may be urgently required. I'd like to have it leave the muzzle before the boar decides I'm within "snack" range. An angry board certainly is nothing to trifle with.
