.22 TCM

Given the limited selection of
factory ammunition from which to
choose, you're likely to contemplate
handloading. Again, not being a
SAAMI-approved cartridge complicates things. Although dies are readily available from Hornady, Redding
and Lee, as are component brass and
bullets from Armscor, data from reputable sources isn't. Be
forewarned: the majority of data available online is assembled by hobbyists, not experts. Until the cartridge receives
SAAMI acceptance, don't expect to find .22 TCM reloading data
from most propellant and bullet manufacturers. Such is one
downside to owning a wildcat and/or proprietary cartridge.

Why?
Although Craig envisioned a .22-cal. handgun cartridge
offering high performance and minimal cost, as is often the
case, secondary uses emerged. As a handgun cartridge, the
.22 TCM affords the M1911 aficionado a low-cost, minimalrecoil experience with which to hone marksmanship and
personal-protection skills. This is especially important for
novices and those who are recoil-shy. It could serve as a
convenient sidearm companion on backcountry forays,
and would be well-suited for dispatching pasture-prowling
nuisance critters when checking livestock.
Is the .22 TCM a self-defense round? According to Armscor's
website, the uses of its .22 TCM ammunition are: "Target
Practice, Plinking Firearms." Can it be employed for personal
protection, though? There are many videos online showing the
cartridge's 40-gr. JHP bullet impacting ballistic gelatin, and
the results are impressive-much better than the terminal
performance imparted by .22-cal. rimfires. However, there's
no denying the advantages gained by using a traditional,
defensive caliber loaded with heavier projectiles specifically
designed for protection. Ultimately, it's the buyer's decision.
For ease of convenience, you can purchase a Rock Island
Armory M1911 combination package that comes with both a
.22 TCM and a drop-in 9 mm Luger accessory barrel.

The .22 TCM is chambered in Armscor's M22
TCM BA bolt-action rifle (top) and TCM TAC
Ultra FS HC Combo pistol. Average velocity
from the 22"-barreled rifle was 2752 f.p.s.,
while the pistol averaged 2066 f.p.s.

One of the best features of the .22 TCM cartridge
is its ability to be used in both a handgun and a rifle.
Therefore, the owner of a TCM M1911 pistol who also has a
M22 TCM BA rifle could use ammunition interchangeably.
Additionally, the aforementioned longarm can use the
same 17-round-capacity, double-stack magazine as the HC
versions of the TCM M1911s. Talk about convenience!
The increased velocity from the 22" barrel of the M22
TCM BA will endear it to varmint hunters in areas where
shots are limited to 200 yds. or less. Beyond that distance,
it's time for a .223 Rem. Used within its effective range,
the .22 TCM is adequate for coyote and ideal for groundhog. Although its been employed for hog control/hunting,
it's marginal for all but perfect shots. There are many better options for the task.

Fire Breather
For accuracy and function testing, as well as
chronographing, Armscor sent me a TCM TAC Ultra FS
HC Combo M1911 pistol and a complementary, unscoped M22 TCM BA rifle ($454 MSRP). Concerning
the latter, as it has a simple integrated rimfire-style
3/8" optic rail, I installed a Simmons Master Series
Prodiamond 1.5-5X 32 mm scope in Weaver Tip-Off
rings. The same 40-gr. JHP .22 TCM load
was fired in both firearms.
Firing from a bench at 25 yds., the
TCM TAC Ultra FS HC recorded
an average of 2.77" for
five consecutive, fiveshot groups. The best
group measured 2.50",
while the largest went
3.03". According to a
Competition Electronics
chronograph, which was
Cartridges from left to right:
.22 TCM, 5.7x28 mm FN and
.223 Rem.
