Re: High velocity in Colts
Closest thing to .22 cal COLT being manufactured now is the Umarex Colt which I believe is manufactured by Walther. I own one and its a fun PLINKER. I'll shoot just about any round that cycles reliably, which includes CCI Blazer, CCI Velocitor, CCI Stinger, as well as any bargain bulk ammo one can buy at Walmart- Winchester and Federal.
Even though I'll shoot Stingers out of this pistol, the reason is I have them on hand when I'm at the range. Truth is, I've concluded that the Stinger is really no better than the other ammo that I shoot from this pistol.
