yeah, sort of
I was interested in the 10mm and answered an ad for a Colt Delta. When I got there, the guy had sold the Colt, but comments that he has a G20, so I bought the Glock instead.
I've always been curious regards the .38 Super, but never committed. The .256 Win mag seems interesting, but I'd like to find an old Marlin Levermatic, and not a Ruger single shot revolver (can't think of model). Was it the Hawkeye?
The various necked down auto pistol cartridges, the .400 Corbon, the .440 Corbon, seem interesting too. What if they necked down the .500 S&W to .44, that would be interesting!
