This tin had 25 rounds left in it, several of which I have shot, and of all the low-power 22 I have (CB's from various manufacturers, Colibri/Super Colibri, CCI Quiets, etc), I like how these shoot the best. I know that they are long-since discontinued, but I am curuious as to just how old they are. I've also used some vintage Alcan primers, so any general information you might have about the company would be interesting.
