I so badly want this cartridge to come to Canada. I'd love to convert a 9mm PCC into it.
Less finicky to reload than teh 5.7, with easily available brass. |

Put a caliber conversion build on a Glock... Made your own bullets and formed brass.
OP delivers! Now put the cal conversation on a Polymer80 frame to complete the "I made dis" trifecta. |

I have a large frame/ long slide ich I need to scratch. I'll do a 10 mike mike on a P80. I wish the .22 kit was a longslide. You c9uld squeeze a few more RPMs out of it. |

With the new large frame p80s I may have to copy you on that 10mm long slide. Sounds very interesting.

I thought the idea of .22 LR was to spin it pretty slowly, so the variable CGs of cheap .22 LR isn't thrown off so much? Quote HistoryQuoted:

Nothing new.
I have gotten the brass forming down. My load with Lil Gun seems to work well. I need to shoot more and would like to chrony my loads. Hoping for 2000 FPS. It is now cold and snowy here in ND, so I don't get out much. I may break down and visit an indoor range. If it was nice out, I would be shooting it more and reloading more. As of now, I am moving on to new projects:) this one is a success, to me, at this point. When I get bored again I will form more cases and cast more bullets ao I am well stocked for spring. |

From your info...I bought the same EAA .38 super mag. Mine is the 17rd.
As you mention, it is a tight fit front to back but has extra space side to side. You may know this already, but loaded TCM rounds will not eject easily. Not a big deal, but found that out. I did buy a box of over priced locally sold TCM ammo to play with. That is about as far as I have gotten. |

I'm going to notch the slide so that live rounds can eject. Shouldn't take much at all. I may be able to angle it so that the notch isn't even visible from the side.
I've got two P80 frames that the EAA mag fits perfectly front to back. Unfortunately they're both the G26 models. It's really snug in the rest. I've been working on opening up a G19 sized frame by a few thousandths. I'm probably going to epoxy some thin G10 on to the sides to remove the side to side play. |

[#20]
I haven't looked at it lately, but the mag is obviously narrower (we have discussed the side to side play) because of that, will the mag catch reach the mag enough to work...I know something will have to be reshaped, the mag or the catch.
Would you add the G10 to the mag or to the inside of the grip? If added to the mag, a glock shaped mag catch slot could be cut into the G10??? Just thinking out loud here;) If you only plan to use the .38 super mags, then you may choose to add the material inside the grip/magwell, I suppose. |
|
|
|
Posted: 12/27/2018 3:27:01 AM EDT
[#21]
I'm going to add it to the mags. Much easier to sand the outside of a mag to fit once I've got the G10 in place. And same thinking as you, going to cut the mag release notch into the G10.

Quote HistoryQuoted: What does the rifle barrel fit? https://armscor.com/firearms/ria/rifle-series/m22-tcm-ba/ Interesting they're stabilizing the little 40 grainer in a 1:16" twist - I guess it works fine for 40 grainers out of the .22 LR, just precludes anything heavier being single loaded. The rifles have an indifferent reputation for accuracy - I wonder if it's the trigger, the bbl, or the ammo? |

That is interesting.
Remember earlier in the thread I didnt think an AR in .22 TCM would make much sense......but now I may be rethinking that?? Maybe a 10" or so Pistol AR. Just for fun, I will see if the TCM rounds will feed from my 9mm Endo Mags. Try some dummies into a 5.56 barrel. The rest of the details would come later...haha. I know someone sells the barrels for AR pistols, but they aren't cheap. |

My 9mm Pmag with Endo mag insert feeds .22 TCM R9 into my 9mm AR barrel with 9mm blow back bolt assembly. Extracts and ejects by hand too.
Blow back may be an easy option. Extraction and ejection may be iffy with the larger 9mm bolt head. |

It may extract a bit quickly and crack necks. CMMG's delayed blowback bolt might be a better fit for this.

Macon Armory has made some DI .22 TCMs using ppsh mags.
Blowback isn't a good option for the TCM. The overbore is going to create more bolt thrust than a 9mm, even when loaded to similar pressures. |

For quite awhile many thought that the coating was Teflon so that the cartridge was “slick enough” to function in the P90/PS90 magazines. This though doesn’t stand up to scrutiny, when there are numerous reports of PS90’s not functioning properly with HIGHLY polished brass. Then several members of the fnforum.net hypothesized that the Lacquer coating is actually there to slightly delay the opening of the action of both the PS90 and the FiveseveN pistol. The Lacquer coating actually is slightly “sticky”. It periodically must be removed from the chambers of 5.7x28 caliber weapons using Carburetor Cleaner. |

Interesting thread. Hadn't seen the TCM9R until my father got one. He picked up one of the RIA guns and shot 3 rounds and already sending it back. Failure to extract and popping primers.
He was asking me if I had seen any info on reloading and I hadn't. He doesn't cast, has anyone seen any other bullet options? |

Mags are dropping free easily now. Used a few layers of foil tape on the back of the mag, heated the magwell with a heat gun on low, put the mag in and let it cool. .38 Barrel is fitted. Only problem I'm having now is the mag catch pushing the mag too far to the side and rounds are catching on the side of the chamber. When I hold the mag somewhat centered it feeds fine. I think once I've built up the sides of the mag it should feed fine. .22 TCM would probably feed just fine regardless. I still need to open up the ejection port as well. I've done pretty much all I can do until the doc clears me to walk again.

Just ordered a barrel liner from Track of the Wolf to try my hand at making a 17L barrel. Being stuck in the house is getting pretty old, I'm beyond ready to head to the shop and start cutting metal.

Are you doing a 17L length slide or a 17 length with barrel sticking out? If 17L, their MAY be a weight issue for proper cycling. Maybe.....

I have a few updates, but they will only be interesting to reloader/casters.
1. Forming your own brass is incredibly labor intensive. I think I have around 125 now. I started hot and heavy, then they just sat there...finished them up recently. 2. I ordered 250 rounds of ammo. 3. I am able to use normal brass (not shortening the necks) now with my cast bullets. I do, however have to use a mag that allows a longer overall cartridge. I found the Amend 2 glock mags allow this. The OAL of the full length brass and my cast bullet is somewhere between factory .22 TCM 9R and .22 TCM. I need to shoot MORE. |

I have also temporarily switched my attention to a Tac Solutions. 22LR conversion on the same P80 compact frame. I now have 3 calibers. I will probably build another slide for the .TCM barrel.

HK_DUDE,
I like the work you have done with your TCM 9R build. I too have been down this road, for almost 2 years. I have both the 9R and standard TCM in pistols, and also an AR Pistol chambered in the 22 TCM running on a DI pistol gas system. I built the ARP to run on factory ammo, but prefer to run my own reloads. I originally milled out a dedicated colt 9mm AR lower to accept PPS43 mags http://blackholeweaponry.proboards.com/thread/2697/22-tcm, but have since switched to a standard lower due to the introduction of the EndoMags(CMMG Version). I must say that these EndoMags(CMMG Version) work well for both the 9R and standard TCM. I learned that the standard TCM ammo will shoot out of the 9R barrel for the Glocks, but as you know the issue lies with the magazine, which leads me to my next point (which seems to have been addressed in this thread), find a magazine that will accept standard TCM ammo while also fitting within the Glock 9mm grip. This is the point I got to with the 9R after I couldn't find any bullets to reload with, and when I switched to the 1911 variant so I could run the same reloads through a handgun and ARP. Now for the ARP and the EndoMags, what I found with these was that the feed ramp angle was too steep, which caused the "nose up" jams within the barrel extension due to the travel distance. I fixed this by decreasing the angle with a file. The next mod is to remove the rear round support (pops in and out) of the EndoMag(CMMG Version) to allow the standard TCM round to fit. To also note, the 9R feeds perfectly when the EndoMag is in it's "9mm" variant. There is a ton more information, but I thought this would be enough to wet the whistles of those who are interested.

I did the same thing..removing the rear spring guide to allow for longer cartridge. I ordered a DI pistol barrel and tried my luck. Shortly after getting it together I was having buyers remorse and started wondering what the point was again...haha. If money was no object, sure....but it is an object for me. The barrel wasn't exactly perfect. That plus the fact that initial testing with dummy ammo wouldn't feed at all from the endo mag made me scrap the project. In my P80 pistol, a 2000 fps round with next to no recoil still excites me. But, due to expense (.22 TCM AR barrels are spendy) it fizzled in my mind to do an AR. Your AR looks like lots of fun...and if the barrels were as cheap as others are these days...I may reconsider some time. Thanks for all your info. |
