9mm

Is there a round that's .45 necked down to .22?

.22tcm can accept lightened pulled ss109.

.22tcm can be fired out of any 9mm 1911.

if ramped 9mm barrel you can load over pressure thank yo better supported chamber with higher rate recoil spring and enjoy wildcat-like performance.

7.62x25

How do you use chicken fingers?

I really wish armscor would get on with a tcm9r conversion for a Beretta 92 already. I mean they have full size and compact Glock conversions, and 1911s, wouldn't a 92 be the next logical step?

>Based on the 5.56×45mm NATO case and shortened so that the shoulder is at approximately the same length as a .38 Super cartridge, the .22 TCM is somewhat longer than the ubiquitous 9×19mm Parabellum and designed to be fired from a RIA line of weapons (which also included 9mm barrel swaps) fed by Para-Ordnance-style double-column .38 Super magazines.

I think there was some wildcat prototype called .224or5 boz but wasn't ever commercially available. The article stated it was very high velocity and I think it was used in a custom 2011
