Anybody know what this wildcat is? I have two clymer reamers. One is marked 25 cal T-M. The other is marked 6mm T-M. They measure out as a 222/223/222 mag case. Really just appear to be a .25-223 and 6mm-223. Could cut a wildcat based on any of the three cases. Base and body taper match a .223. I didn't measure the shoulder, but appears standard 23 degree to match a .223 case.

Anybody know what the T-M stands for? I'd expect them to be marked .25-223 or .25-222 or .25-222M.
