and doesn't even REMOTELY approach the momentum, frontal area or energy of a 2 3/4" 20 ga slug. Since NOBODY considers EITHER the 30 Carbine nor the 20 ga a viable stopper of bear charges, the .44 revolver isn't, either. At least the 20 ga auto and 30 C offer FAST repeat tries at the brain, with a LOT more likelihood of success than anyone can claim for a .44 Revolver. The 20 ga also offers utility with buckshot and birdshot. The .44 offers basically nothing of any real value.
