.22 TCM
I have a chance to get a Armscor .22 TCM. I'm wondering if anyone has anything good, or bad to say about this gun and round.

What will you use it for?
Not suited for any competition I know of.
No track record in actual combat.
A loud plinker.0 -
We are gun enablers here, buy it and give us your evaluation. I shot a 221 Fireball in an XP for years. I now shoot my model 53 S&W Jet.

It's the 7.62 X 25 Mauser/Tokarev cartridge, necked down to .22 caliber. Reed in Ok City. Made the same cartridge, for rebarreled Czech VZ 52 pistols years ago.
Great care must be taken if reloading, to not push the envelope. Very high pressures can be generated, by using fast burning powders.
It's a very interesting concept. It kind of surprised me that Armscor would bring it to market. As the potential for catastrophic failure is great, if reloaded with fast burning powders. If you buy one, stick to factory loaded Armscor ammo.0 -
Couldn't you just use the slow burning powders that the bottleneck case calls for? No need to get all frightened of fast burning powder if you don't use it.
And it is not a 7.62x25 neckdown a la Reed. .223 case head diameter, enough smaller that it takes its own extractor.0 -

I agree on the slow burning powder, if you reload. Don't agree that the small difference in head diameter,( .015 ),would make any difference. If the chamber was reamed to 7.62 Toke, external dimensions.
I believe that Armscor uses .223 rifle brass because it's heavier with a thicker wall and web. This serves two purposes. Makes for a more pressure resistant case, and reduces internal capacity. Unfortunately it makes it much more difficult to reload, because of the added steps in converting .223 brass to TCM.
I was fixing to buy one of the TCM's. All that were available, at the time. Were double stack, commander length with a extra 9mm barrel. I passed, and bought a FN 5.7 instead. When I found out about pressure limitations, and extra hassle converting .223 brass. I was happy I did.0 -
I am the other way 'round. I found the accounts of troubles reloading 5.7 to be alarming. 0 -

Been reloading it for awhile now, (FN 5.7 pistol). Slow burning AA 9 powder. Cronoing all my loads. So far so good, ( knock on wood). The unlocked blowback mechanism. Creates a built in fudge factor. Vis a vis, the locked breech TCM.0 -
Friend has one with a 9mm barrel for conversion. With 9mm barrel it will not chamber. He says 9mm round sits too low. 0 -
OK, thanks guys. Just thought it sounded like it might be fun. But if it doesn't chamber the 9mm, that's not good. I don't think I'll be reloading, so that all doesn't really matter. But thanks for the info anyway. 0 -
The 9mm barrel isn't milled out fully, needs more of a ramp. Send it back.They will fix it. 0
