You want a "crack"? Wait a bit until someone puts out a carbine chambered for the .22 TCM; that should clean your sinuses out! I have a Rock Island 1911 that runs it and had people six-lanes away at the range come down to see what kind of howitzer I was shooting. Between the 2000 fps-plus velocity noise and the big fireballs it made, that gun was quite the topic of discussion. Not much recoil either, about like a .22 Mag. After I blew through a box of ammo (50 rounds) and went home the range called and told me they were banning it because it's "too hot"! Oh well, there are other ranges! Can't wait until someone does an AR platform for the stuff.
