Pistol barrel rifling

I've done this and it works as long as there is not too much lead fouling in the barrel, in which case, you will have an overpressured round. Not ideal in a Luger.

A friend of mine blew up an M16 by extensively firing lead .22 rimfire through it full auto with a conversion unit then swapping back to .223 without scrubbing out the barrel. After I saw that, I built a dedicated .22 rimfire upper for my M16 and use that, and only that, with .22 rimfire.
