That Rock Island 22TCM is ONE HECK OF A GUN! Had heard of the round, wanted one, no one had any in stock and order time was forever...till I wondered into my local shop and found one used (maybe had a box fired through it). They had NO idea what they had (spent 15 minutes trying to tell me they'd throw in some .22lr ammo in with it, lol), walked out with it for $400! LOVE watching that fireball come out the end of the barrel when you pull the trigger and the melon burst at 50+ yards everytime! Nice collection!
