.321 GNR in a K Frame Revolver?
I'm considering having the cylinder on one of my .32 caliber S&W K frames (Model 16-4, full lug barrel) reamed to .321 GNR. What's the performance folks have experienced with this cartridge out of a 6" barrel?
I have an 8 3/8" I'd consider as well, if the cartridge benefited greatly from the longer length. However, that one isn't nearly as handy.
