Until the .41 Special is invented and becomes popular, the .44 Magnum will always be a more versitile caliber. The .41 is so close to being almost a .44 magnum. 210 and even 180 grain bullets are available for the .44 Magnum.
Remember that the .44Mag/Special is really a .429 caliber gun.
I have even shot .433 roundballs for muzzleloaders out of a .44Mag using light charges of fast burning powder.
