Question on the 22 tcm

[John S]

For reloading this cal. ( 22 tcm) can you use IMR 4227 power? Looking for someone data from it.

Interesting cartridge.

Scratch what I said about a faster powder.
Here is an article about loading the cartridge. Seems you are on the right track with that powder.

Thanks all. Got the gun and learned how to make the cases. I used 800x power. Ended up with 4.5 grs., with a speer 46 gr. Spfn, cc I 400 primer. It did .167" group 3 shots at 25 yards.
