..and that is what I am saying... You can't compare a .41 Magnum to a 10mm any more than you can compare a .44 Special to a .44 Magnum... You can put them in the same size guns but because of the difference in case size you can't run 330 grain bullets in a .44 Special anymore than you can run a 250 in a 10mm.
But since most people run 210s in their .41s and there are few ,41 loads over 220 grains comparing a 210 .41 and 200 .401 there isn't that much of a difference. .
..and my bottom line was the 10mm was a great round for mid-size frame revolver. And as of right now there are no mid-frame .41s for sale and few large frame. If it wan't for Ruger the .41 would be on life support and it is my favorite revolver round.
