I was looking for something that might interest me in small cartridges and was something that would lend itself to available brass. The cartridge is the .223 Short which has a case about the size of the 5.7X28 FN case but made with stronger .223 brass. It's bigger than than the 22 TCM and may work well in modified AR mags. Here is a URL to info on the cartidge 223short.com/I sent an e-mail to the originator to find out what he used for a die set -- I'm hoping it's just a modified .223 set or a modified 221 fireball set. Edit 8/22/16 -- Not much information is available on the parts necessary to make this cartridge. I never got a reply from the originator and it turns out the chamber reamer was a one-of-a-kind job and I'd have to go to the expense of having a new reamer made. If I wanted to go the slightly smaller route I'd go 221 Fireball. |

It's funny, I would like the .223 Short cartridge but then the reason was less powder for a cartridge that would fit the AR bolt -- then I realized the 22 TCM might just be better. I'm going to do a rifle in the 22 TCM since I don't have to form cartridge cases and I think the M1 Carbine magazine would work great with them. I just need to wait and see what happens.

I decided the 22 TCM was a better choice since brass can be gotten already formed or, if you don't mind the stubby little bullets, you can even buy loaded ammo. I found that I can load bullets like the 40gr V-max out long and will work just great in an M1 carbine mag and Tim makes an adapter for those mags to work in the AR-15. The 22 TCM should make a nice little varmint rifle.

22 TCM is a great round in the AR.
We're also doing a .222 and a .221 Fireball. The .222 cause the kid has a varmint rifle and tons of brass, and the .221 because it make sense with a 1:7 barrel and 69+ gr bullets.

Glade to see your're back. Your right about the .222 and .221 -- I've got a bolt action in .222 and love it and an AR in a close round to the .221, the .17 fireball. with the cost of things these days I've got to go smaller and so I want to try the 22 TCM.

tim,
I'm just checking about a .222 barrel. IT's the wrong time of year to be buying myself anything but I would like to know what a heavy 22" .222 barrel might cost in CM. I'm talking with a gas block area with a diameter of .875". I have a bolt gun in .222 but the darn thing starts to string vertical when it gets hot and I wanted to build a free float in the same cartridge with one of those heavier built receivers like the Lo-Pro sold my Brownells. No flash hider, just a target crown with the gas port at rifle length. Nothing fancy.

My son Jake has been spearheading the .222 project and is getting some good results with 4895 and 335 powders. As soon as our reamers come in we'll get a few barrels done for the AR, time and sales permitting. Our first "ammo" priority is getting the 22 and 30 uzi dies and brass together.
