About the TCM series

The TCM series was inspired by the need for more firepower in lower caliber firearms and ammo. The series was designed and developed by Armscor/Rock Island Armory executives – President, Martin Tuason and Master Firearm Engineer Fred Craig. The TCM stands for Tuason Craig Magnum.

The .22TCM bullet has been called the “Flame Thrower” by one prominent reviewer and has been embraced by hunters, self-defense and shooting enthusiasts.

The overwhelming demand for the bullet’s industry leading high velocity and stopping power has prompted the company to expand its US production facilities.

Armscor USA .22TCM bullet features:
• Velocity – 2,800 feet per second
• 40 grain jacketed hollow point
• Maximum expansion
• Centerfire
• Precision engineered to meet all SAMMI specifications

    Any one have an idea about ballistics for this round, drop at 100 yrds, etc?

    • The basic ballistics are shown above. I’ll have to contact Armscor for specific ballistics at 100 yards. I would think less than one inch.

    • Watch the “Shooting Gallery” show titled ‘Philipines’. They discuss the rifle and handgun.

      should be better than a 5.7 out of a PS90, this round has more powder, and the rifle has a longer barrel, however that doesnt necisarily mean better accuracy, build quality has a larger impact than anything in my opinion, it should at the very least be more accurate than .22WMR because the .22TCM uses smokeless powder, and a lot more of it, meaning that the barrel should take much longer to foul with significantly more rounds on target between cleanings

  • Shankbone

    I. Want. One. NOw!

    • I have contacted Armscor too. They tell me it’s about a year wait. I’m not a patient person . . . arrrrrgh.

    The .22 TCM is still way too proprietary for me.

    Buying a firearm whose ammo can only be bought from one source makes me feel iffy.

    Meh. I liked it better in their M1911:

    I have been in touch with Rock Island Armory and plan to buy one of these when they become available. Personally, I hope that they consider selling barreled actions as well in the future and offer a 16.5″ barrel option. This could be made into a rifle that is as compact and light as a sporting rimfire, and it would be a lot more powerful. I do think the round has fantastic potential as well. Sako used to offer a proprietary round called the 7×33 with similar performance in Europe and many of the old rifles chambered for it are treasured in Scandinavia. RIA and Armscor might just have built its modern replacement.

    Uh hello .223. , lets not reinvent the wheel here.

    People on all of the forums I have read are surprisingly very resistant to the idea of this round. Read an article in shotgun news where they praised it, and I think it’s a great idea, and here’s why.

    1) It can be made from .223 brass, not a 9mm necked down that people are convinced it is. All they have done is essentially shorten the .223 Remington and lower the bullet weight.

    2) I believe it has the potential to match and even beat the versatility of the 22 mag. It already has beaten its ballistics from a pistol, and I believe that much can be obtained from a bolt gun. You can run the same ammo through your pistol and rifle if the situation should ever require it. And top of the fact that unlike the .22 mag…

    3) It’s reloadable. So combine this with the fact that you can potentially cut your own brass from a .223 Remington and it’s ballistics, I find few reasons that this round is a “bad” round other than people refuse to accept something that’s new. While I do respect all other cartridges and as someone pointed out they wouldn’t trade their .223 for the gun, this round isn’t meant to replace the .223. This gun is for plinking with a pistol and for small, fur-bearing sized game. I’d hate to see what a .243 or a 6mm would do to a fox, and a .223 for that matter. And considering the fact that most calibers for these game tend to be rimfire, a centerfire round makes sense in my book.

  • What’s the price? That’s the most important thing to me right now in this screwed up economy.

    I previously had a a very bad experience of using .22 mag Armscor rifle which is not an accurate rifle. I bought it from an arms Dealer in Pakistan and wasted lot of time and money in shape of bullets, changing scopes and scope rings but all gone in vain. I tried to zero that rifle but found no result because the patterns at 25 yards are of 2-2.5 inches ( as it should be with in 0.5″ inches or max an 1″ and at 100 yards, bullets even could not make a pattern of 6 inches and sometimes no bullet found on target at 100 yards. i dont know how .22 TCM be accurate, i can imagine in view of my previous experience only. In the end i can say only that Armscor rifles are not accurate if you really need to have a good result.

    • Denver Garkie

      do you still have the rifle? i refuse to believe that a .22 mag rifle of any quality would fail to get a 1″ group at 50 yards, there must have been a problem with the barrel, ammo, or scope/mount maybe the rings and scope were fine, but the method of attaching to the barrel was damaged, did you try iron sights? i have a micro pistol that shoots .22 long, it has a 3 inch barrel and it will keyhole at just 30 yards, and i can still get a better pattern at 25 yards(from bench) than said rifle

      • Guest

        Sounds like poor shooting to me.

    “Precision engineered to meet all SAMMI specifications”

    Does this mean that the 22 TCM will finally be SAMMI caliber? That would go a long way toward helping people adopt this caliber.
