Last month we described the overall UTM CTA system, and this month we have usage results.
Target can be set up anywhere
The first step is setting up the target. As we mentioned last month, the conversion kit comes with everything including an easy to set up target.
This target consists of several components, all of which are easily assembled in minutes and store inside the hard case:
- Target Hanger - this is the large main component that holds everything
- Target Holder - this foam piece is lined with sheet metal to serve as backstop
- Cardboard Printed Targets - kit includes 3 printed carboard targets
- Bungee Cords - two hangers allow you to place target anywhere
The target setup consists of unfolding the main hanger which has a pocket for the foam target holder/backstop to drop into place. Individual cardboard targets then slide into this holder. The whole assembly can then be hung via the bungee cords where ever you'd like to shoot.
Shots outside of the target itself are safely stopped by the target hanger.
Projectiles collected inside target
Shots that hit the target are effectively stopped and trapped by the target holder/backstop which has a downward canted sheet metal face (as shown in the photo).
We fired at point blank range to see the effects of the projectiles on the backstop and none did much more than mark up the sheet metal where they hit.
Overall, the target system is a nice extra that comes with the kit, and works very well not only to stop the shots, but to keep everything neat and tidy by catching the projectiles.
For those who are curious about shooting something other than the target, we did some side testing and can confirm that they will definitely leave a hole in your drywall (but not penetrate all the way through), will knock over but not penetrate a plastic soda bottle (the thicker kind- not like cheap water bottles).
Expended round with projectiles
Though it is definitely not recommended by the manufacturer, it will not penetrate denim, but it will leave a black/blue mark on the skin underneath. Do not try this at home- we used a very sophisticated human analog to safely test this!
Taking a look at the projectile, it is made up of two parts: a small aluminum plug with a rounded blue plastic nose cone.
The projectile fits into the "brass" portion of the case, and when fired one charge fires the projectile down the barrel, and another activates the action.
Projectiles after shooting
In this way, the force that shoots the projectile can be controlled separately from the larger force required to operate the action. In our testing of 100rds we never had any failure to fire, eject, or load, so UTM has managed to make this a very reliable round.
The nose cone on the tip of the projectile serves to provide a "soft" rounded tip, which probably helps guide the rounds into the chamber. In addition, it may actually engage the rifling of the barrel as the blue plastic seemed to be marked after shooting.
This may aid in stabilizing the projectiles, as they all seemed to hit the target nose first at all ranges tested, and fairly accurately as well. Our ranges ranged from point blank to about 50 yards, though the recommended range is about 30 yds.
Firing is via rimfire for safety
We found the projectiles to be rising to about 20yds (i.e. hitting below point of aim), and then dropping over zero again at ~30 yds (our zero), and about 2 feet low at 50-60yds.
We touched upon it last month, but it bears repeating again that this kit was engineered for safety.
The UTM CTA fires using an offset firing pin. This prevents any live ammunition from being fired with this bolt in place.
The blue bolt marking is visible from the ejection port, and as long as this conversion is installed, there is no way a live rounds can be fired even if a magazine was inserted, a live round chambered, and the trigger pulled.
M193 (top) vs. UTM CTA (bottom) @10yds
We very crudely tested point of impact in relation to a live zero with the image shown at the right.
The top group represents a 3 shot group fired at approximately 10 yds using M193 ammunition
The bottom group represents a 3 shot group fired from the same rifle, at the same range, but using the UTM CTA ammo.
Because it is at 10yds, the UTM would still be rising and we suspect would be about center on the target at 20-30yds, but because this test was done outside of a range we did not extend those ranges out to the full 30yds.
Video shooting the UTM CTA indoors
Overall, the conversion kit worked flawlessly. Accuracy proved to be good at ranges to 20-30yds, and we tried rapid firing as quickly as possible and experienced no malfunctions. For those that asked, the kit as it currently exists is semi-auto ONLY (it will not trip a sear).
It comes complete with everything you need to get up and going including ammo, a target system, cleaning tools, and a nice hard case. As such it is a very good way to practice outside of a range, including indoors, or to get new shooters familiar with as realistic of a round as you can get.
