I'm curious if anyone has used any of these un-popular calibers. After reading about them they're both powerful enough for effective CCW and the .41 mag sounds like a pretty good Deer round. S&W makes a few affordable revolvers in the .32 mag.

IMO these rounds are headed the way of the Dodo bird...
There's nothing a 41 can do that the much more popular 44 mag can do (or better), and ditto for the 32 and 38 spl/357 mag.

I like to play with many calibers, even wildcats, but there is no practical reason to go for any round different than the most popular ones, in handguns or long guns.

I would think 41 mag would be a good medium between .357 and .44, but on the other hand sometimes I load "lighter" loads in my 44, or just use 44 Special.

Agreed - Buy lots of brass now.
