If you check Ammoland or Sportsmans guide, or Midway you find 10mm running slightly more than 45ACP.
But then it's FQ
I do agree with him that it is a matter of Revolver vs Auto.
41 may be a cult classic, but there are at least 2 other more common hand gun hunting calibers for revolver, the .357 and the .44 Mag.
On the other hand, saying the 10mm "never took off" is just plain ignorant.
As the first practical hunting round for semi autos they are produced by Glock, but with the possible exception of Ruger ( for now ) Every major US manufacturer of large frame semi auto's offers a 10mm version, and then there is the EAA Witness 10, Lone wolf now offers an Upper for the Glock 20 that includes a 7.5 inch barrel and Trijicon RMR sight specifically designed for hunting.
The revolver had been around for about 100 years when the first practical hunting round for that came out (.357 Mag 1935ish )
As we celebrate the 100th anniversary of the 1911, we have the first practical hunting round for it.
