Ran across an odd round today.

Was at the range this am, and noticed what appeared to be some very short magnum brass. Found a couple apparent misfired rounds laying around. They were 22 TCM.... interesting history
Next to a spent .243 casing, for reference:

An Official Journal Of The NRA | Tested: The .22 TCM Cartridge

Whether hot-rodding an M1911 or mid-range varminting, the .22 TCM is poised to please. Anything with “Micromagnum” in its name was sure to get our attention.

I bet that guy gonna wish he'd done a more thorough job of pickin up brass.
I'd say it provides no new niche in a rifle...
Would make a good farm hipgun, but the blast!

I believe that’s the Rock Island Arsenal invention. Reinventing the wheel to me.

Never heard of it, that's interesting.

isn't it the one the made to fire in the .45ACP for training.
We talked about making some short range hunting rifles in it.
That is how the Accurate Powder TCM came about I believe.

I’m not sure about the .45 part, although I wouldn’t doubt it. I do believe you’re right about the powder.
It seems to me to be another attempt at putting a .22 Hornet in a pistol platform like the 5.7x28 although the TCM would probably have a velocity advantage

 

[Jester896]

@bullgator sorry...I meant .45ACP platform but it is closer to a necked 9mm IIRC...I have a few cases somewhere.

 

[Dub]

Yep.

Necked down 9mm case.

Attains really high velocity.

Accurate Powder markets a powder for it.

22 TCM cartridge. Producing 2,000 fps at the muzzle with virtually no recoil, this accurate and fun little cartridge brings handgun performance to a new level for small game hunting and plinking.

I have a stash of those that came with some bulk reloading gear. If anyone is in need I can dig it out, I was going to repurpose what I could. Does anyone need any?

I used to have a 1911 that was interchangeable between 9mm and .22 TCM. It was before I started reloading and .22 TCM was a little pricey. It’s a fun round to shoot though.

Big boom, big flash and minimal recoil.

Seems like those short little bullets would be a pain to reload.

I could see where it would be fun, though.

My brother has one. His a Commander sized RIA 1911. The 22 TCM beats the 5.7 in a pistol length all day long ballistically. And the ammo is significantly cheaper than 5.7 directly from Armscorp. Also, you can drop in a 9mm barrel in the same gun. 18 +1 double stack, uses the same mags as Para Ordnance.

They made a 22TCM 9R version that was a chopped nose so it would fit in a 9mm length action. You can get barrels for Glock 19. Buddy of mine bought barrel, but had issues with it. I think they failed to polish the chamber causing extraction issues.

Haven't had any issues with the ones I loaded, just have to have a short nose bullet to fit in mags.

Buddy gave me some pulled 22mag bullets he acquired decades ago and they have shot great.

The flames out of a 5” 1911 are impressive.
