My buddy has one. First I’d ever heard of one and of course, first one I ever saw. Developed and made by Rock Island Armory. A cute little cartridge with ballistics I’d like to have. 40gr bullet about 2600 fps would be handy for a lot of things and a lot of fun to develop a load for. Unfortunately it’s a 3-4 moa gun, his is and the reviews I’ve read the others are too. His best group was about 1.25” at 50 yards and the majority were 3-5 inches, at 50 yards! This was factory and reloads.
Cartridge was developed from a 223 case so I think it‘d be pretty easy to build a rifle for it. Not that I know what I’m doing, I don’t, but for those of you that build rifles…

He wanted to send it home with me to develop a load but I didn’t take him up on it. I guess I would have if we had better weather to shoot but it will be a couple of months before we get “nice” shooting weather. Maybe when I pick my daughter up from school in March I’ll stop in and get it…
What I’d rather do is work on it with him as he’s a new reloader. He’s 2.5 hours away from me so I need to have him come for a weekend and we could do nothing but load and shoot…. Maybe we can make that work.
Anybody have any experience with the 22 TCM?
