22 TCM
« on: March 02, 2020, 07:33:29 PM »
Any of you have experience with the Rock Island Armory 22 TCM ?

From what I've seen thus far, it seems like a good solution for me for mid-sized varmints out to around 200 yards, but they also sell a semi-auto pistol combo gun that can shoot both 22 TCM and 9 mm. I just wish they made a semi-auto rifle variant chambered in it.

Never heard of it but itís an Interesting looking cartridge.    Kinda like a 223 short.

Pretty much what it is. I didn't realize that 223 and 9 mm case diameter were the same.
There's a couple YouTube videos showing people  making casings for the 22 TCM by cutting down 223 casings, annealing the brass, and running it through the sizing die.

The appeal to me is having another cartridge that can work in both a pistol and rifle. Now all they need to do is develop a carbine style rifle with the same ability to interchange barrels to be able to shoot both 9 mm and 22 TCM.

Could you just neck down the 9mm case or would that be way too short?

It doesn't really appeal to me. I think I'd be more interested in 5.7 or even 22 magnum. I'm sure the ballistics aren't as good, but multiple manufacturers produce the guns and the ammo. 22TCM isn't really catching on, and I don't think it's going to. Unless I missed a large following? The caliber is probably only going to survive as long as Rock Island decides to make it. I really like to stick with things that will be around for the next 100 years.

Mass availability certainly is a benefit.  I can see the attraction to the boutique stuff tho. 
I resisted getting a 9mm for a long time simply to avoid having to search for and stock another caliber.  All my pistols are .45
Not a huge deal but that was the rationale if you want to call it that.  My 16yo son just HAD to have a CZ Scorpion EVO which is a 9mm PCC so I caved and bought it for him for xmas.   Talk about greasing the skids to get one by Mom
So how does this TCM compare to say the .17HMR   its rimfire but same application I think.

No, it's too short. From what I read, the guy who developed it couldn't find a pistol cartridge that would fit. There's also a slight difference in the diameter between 9mm and 223 casings.
I do have concerns about the continued support of the round for ammo, but the ability to make your own would continue since the parent case is the .223 round.
It seems the ballistics are much better than both the 22 Mag and 5.7mm.

Well, none of the local retailers had one in stock. I looked out to a distance of 150 miles with no success.
Finally decided to just do a fit check on a double stack 9MM handgun figuring it should be close enough.

I decided to go ahead and pull the trigger and order one through a local dealer. Along with the gun, I ordered an extra mag since all reviews say it comes with only one and a couple hundred rounds of ammo. State hasn't clamped down on gun sales yet (which surprises me since it's Illinois), but will have to wait and see how the COVID-19 and back-log for background check effects the delivery.
My biggest deciding factor was the almost non-existent recoil every video touts. Ballistics shows it's a flat shooter out to about 80 yards from a handgun which should make it a good choice for the wife and granddaughter.
Even if they miss, it sounds like the muzzle flash would burn the invader to death.  >:(   LOL
