Very exciting! I hope it works!
Wouldn't a hotrod cartridge like this benifit from a longer barrel? I wish they made it in a 17L. |

Just thinking out loud here....
Would you have to line the chamber and recut also, since the 9mm cut chamber is larger then the .22 TCM chamber? That would get paper thin? Or am I smoking something?? |

Probably. The liner itself would be thin, but it'd be supported by the Glock barrel.

I know early on in the thread I mentioned doing an AR.
However, once I have actually thought of it, I don't see an advantage. I already have short AR pistols (also SBRs) so what plus would a same size AR in a cartridge that has lesser ballistics then a 5.56? I realize a 7.5" 5.56 looses alot of velocity, but it must still be faster than the .22 TCM. I like new things and projects though...for sure. Am I missing something maybe? I see it in the pistol for sure, but not as much in an AR size package. |

I'm working on a .221 Fireball AR. I think it has a lot of potential in the 7.5" barrel. Shouldn't lose much if any velocity to 5.56 and will have less blast. Gun will also be 1/2" shorter than a standard AR. Now if I could just stop getting cut on so I'd have some time to finish it.
But yeah, the TCM is kind of pointless in an AR. |

Love some 762x25 action. It's what got me into bottleneck handgun cartridges ages ago. It's too bad there is no real modern handgun in tok.
That's what makes the TCM9R appealing to me. 22 micro mag is just awesome. |

Would have went to my outdoor range today, but it has been raining on and off all day. The problem is that it closes for the year after tomorrow.
So, loaded 15 rounds into my 15rd Pmag and shot them into the otherside of the ditch on a near by gravel road. I saw a fireball on each round. It is a cloudy, rainy day. I didn't pay too much attention to recoil, but it was mild. Fired all 15 as fast as I could...it ran 100% and locked back. Ejection was pretty consistent, but I managed to only find 9 pieces of brass. So far, so fun! Glad I made the purchase. No I want to chrony them and see if I can hit anything. |

It stopped raining. I was able to put some rounds on paper, but didn't have my chrony.
Function was perfect now for 65 rounds total. All shooting was done at 30 feet. I am not much of a handgun marksman. This was 5 rounds resting on my shooting bag. The first round would always go high.  Attached FileThis next one is standing at 30 feet. I was only running 5 at a time through the gun. I marked the first round from the 3-5 shot groups with a "1"....the other lower left shots are all rounds 2-5 of the 3 total mags. The 1st round high and right seems consistent. Again...I don't claim to be a good pistol shot.  Attached FileIt is so fun to shoot. Soft recoil, but still enough to be fun and still know you have some power there. It is a pleasant big boom! Not an ear/brain piercing crack, more like a low baritone, like a harley...haha. I had foam ear plugs in. I need to order dies, start hacking up some LC brass and get my mold ordered. I also shot about 100 rounds of 9mm in the same gun..the 9mm was boring compared to the .22 TCM9R. |

It has enough potential that I ordered dies, etc...
Firat plan is to form my own brass...I already have the little HB saw, as I also form my own .300 BlK brass. If that sucks, ai will have to buy some brass, but I have to try as that is part of the fun...gives me a self sufficient feeling to make my own brass. Still undecided on what I plan to do for bullets. At first I may try some backwards Vmax bullets for fun. |

We shall see how that goes. 5.56 to .300 blk was pretty easy, so I think this will be similar. I just have to anneal these, or so I read. I will get a shipping notice once the mold ships....the website says to allow a couple days. |

Fit in my Glocks and other P80s is really snug, nothing a few seconds of filing on the back side of the magwell wouldn't fix. It feeds and even activates the slide stop in my G19 using 9mm. Don't have a TCM kit yet, so can't check that. I'll have to mod either the mag or the mag release to get it to lock into place.

I typically use Hornady dies for most things. I also have a few special Lee dies that I really like.
If you are forning your own .22 TCM brass, do NOT buy the Lee die. It has a vent hole right at the shoulder and it wrecks most of the brass because the unsized brass lip catches the hole and either creases the neck and shoulder or completely wrecks it. Yes, I am annealing and lubing. Hornady dies on the way. Why didn't I just by them first? The lee die works great for just resizing factory TCM brass. And, the lee trim die and cutter is slick as $hit! |

Good thread, I have been planning to do the same for a while now.
I also may cast for this since there are no bullets available. A pound of lead will make a lot of these little bullets too. Cool round, not a lot of publicity for it, hope more people get into it. |

I received the Hornady dies today. Been playing forming brass. I think I have it down pretty good.
Figured a good length to cut the .223 case to. Have a system to anneal. The hornady sizing dies seems to work best with the decapping pin/neck expander out of the die to form the case, then run the batch through them again with that back in place. I had to turn the die another turn to knock the shoulder back a little to fit properly in the glock conversion barrel. Tracking says the mold will arrive tomorrow. Not much more I can do until I have some bullets cast to mock up a few dummy rounds to make sure they chamber with a bullet in them. Hopefully I have chosen cases that the walls aren't too thick. I dont want to turn necks. I am not making my own brass to save money. I love a new project and it makes me feel somewhat self sufficient. Also, if they stop making factory brass, I will be good. |

The powder coating is easy. There are many videos on youtube that go step by step.
I use a plastic bowl with a lid (the recycle triangle should have a 5 inside it.....this seems to be the best plastic to create static electricity), drop in your bullets, add a small amount of powder coat powder, shake, spin the bullets around until they have a decent coat of dry powder. Then shake off the extra (I uses a wire bin that was purchased at Bed bath and beyond) powder and put the wire bin and bullets into a 400 degree toaster oven for 20 mins. I quench when done. I have working dummy rounds. This has been the biggest pain in the a$$ to get the exact right sequence down for forming/sizing/etc.....the challenge is to try keep the neck thickness thin enough so the loaded round will fit in the chamber. I have it down.....now I just need to load a few live rounds and see if they function. Added: To get everything to work properly, my trim length is down hovering around 1.00" or a few thousands over. Shorter then spec, but good neck tension and I do a light crimp with the cast bullets.  Attached File |

I fired a mag with 4 reloads and 4 factory loads this morning. All functioned 100%.
Primers are fattening, but nothing major. They feel and sound very similar to the factory rounds. Now I need to chrony them and see if they will hit the broad side of a barn. I want to get 2,000 FPS and I feel I can. More to come, but not sure when. |

Many forums that I have been checking out seem to love H110/W296 as well as Lil Gun. Some say Lil Gun is better. |
