I have one final thought on the .41 Mg.
I think one of the redeeming qualities to the .41 Mg. over the .44 Mg. is that it is just enough less punishing to the shooter and to the frame of the gun, that it is to be preferred in some cases over the 44.
It is indeed easier to shoot well and the thrust generated by the 41 is about 9% less than the 44 given 40K loads in both. (think S&W N frame here)
In the meantime it will kill just about anything that the 44 might be used for. Now I know, the 41 may not be a great grizzly gun, but when you get right down to it, neither is the 44.
