i too am a 10mm fan, so i would pick that. but i also love my sbh in .44mag loaded up hot with 300gr bullets.
ive got an uncle that regularly hunts black bear in minnesota with his srh in .41mag.
the .41 falls dead between the 10mm, and .44mag, but i believe it has a "sharper" slap of recoil than the push of the .44mag.
if you want wheel gun id go with .41 or .44.
if you want auto go with 10mm.
There is only one tactical principle which is not subject to change. It is to use the means at hand to inflict the maximum amount of wound, death, and destruction on the enemy in the minimum amount of time."
