USFT rifle – Part 1
by Tom Gaylord
Not what you might expect in a rifle, the USFT requires a little orientation.
B.B. Pelletier invited me to report on the USFT rifle because several readers have expressed an interest in the gun. The first time I saw one was when Steve Schulz brought his new rifle out to the DIFTA field target club, where I used to shoot. Steve’s gun wasn’t actually a USFT; it was a hand-made rifle called a Simple Simon made by Larry Durham. I was intrigued that Steve’s rifle got 55 shots with Beeman Kodiaks at just under 900 f.p.s. on a fill of just 1,800 psi! That was less air than any other precharged rifle had remaining when all the useful shots were finished. The rest of us were filling to 3,000 and Steve only had to go to 1,800 to get the same results.
Steve is one of the finest field target shots in the world, so the fact that he did well with his new rifle was less impressive. He’s the kind of shooter who can outshoot most of us with our own rifles, so high scores from him are not exactly news. That clouded my observation of the rifle until I got one of my own. Having played with one, I now I understand that the ergonomics far surpass any other competition air rifle.
The appearance of the USFT commands attention. It doesn’t look like anything you have ever seen. In this report I will walk you around the features that set the gun apart. For, it is the egonomics, not the fact that it runs on low pressure, that makes this air rifle the star that it is.
One warning. This airgun is made for the sole purpose of winning field target matches. It isn’t a plinker; it isn’t a hunter and it certainly isn’t a general-purpose air rifle. If you want one of these, want it for the right reasons, because you’re going to have to invest some of yourself in the relationship. I think you will understand as I explain the features.
The USFT is a production gun with a lot of hand work still applied during the assembly process. Tim McMurray makes it, and he told me that 113 rifles have been sold thus far. He’s looking at starting the second run soon. The rifle just took four of the top five places at the U.S. national field target matches, so the demand for them is very heated.
The valve is the heart of this rifle. It’s an impact-type that is completely different from any you have seen before. It has a low-mass hammer that strikes an ultra-thin valve stem to open the valve against a very weak return spring. The air transfer port is elongated and runs inside what I must call the bolt, for want of a better term.
To achieve the velocity my rifle gets (an average of 938 f.p.s. for Beeman Kodiaks and JSB Exacts, alike), a lot of air must flow through the barrel. That means the valve must be open for a longer period of time, because the air pressure in the reservoir is lower than that of a conventional PCP. A long barrel allows the push on the pellet to be sustained longer, so, just like that 4,000-lb. Cadillac that is so difficult to get rolling when one person pushes it, eventually the pusher builds momentum and can push the car as fast as he can run.

This valve was designed to be repaired by the user! It comes apart easily because both the designer (Durham) and the manufacturer (McMurray) wanted it that way. You can even purchase the tools and parts to rebuild your valve. I did, even though I feel confident that the low operating pressure of the gun means I may never have to touch it. Airgunners will understand how I feel.
To load, the bolt is rotated to the right, exposing the breech of the 25″ Weihrauch barrel. There is more room for loading pellets than anything other than a breakbarrel. The bolt glides on bearings and seals that seem bank-vault solid. There are no detents to alert you to when things are in place – they just are, and you soon learn to accept it.
Cocking and firing
Cocking the low-mass hammer is impressively easy. Just pull it back until you hear the sear click. It doesn’t take more than a few pounds of effort. If you want to dry-fire the rifle, just cock the sear without moving the hammer. The trigger-pull feels the same either way and no air will be lost that way. Not that field target shooters dry-fire their rifles that often, but you will want to impress your friends with that trigger, whose pull is less than the 8-oz. minimum of my gauge. I estimate a pull of one or two ounces at most.

The fill nipple is a male Foster hydraulic fitting located on the left side of the receiver. It comes with a female cap, protected by a vinyl cover so no dirt gets inside the gun between fills. McMurray located the fill nipple on the rifle’s left rear to keep shooters away from the muzzle for increased safety. I like the Foster quick-disconnects because they are easily obtainable anywhere, and three of my PCPs now have them.

While Steve’s rifle filled to 1,800 psi, mine needs only 1,650 – further lightening the burden on anyone who fills with a hand pump. I don’t yet know how many shots I will get, but the useful shots are within a string that doesn’t exceed 11 f.p.s. so far. Knowing that PCPs do change as they break in, I will watch the gun’s performance during the first year. Mine comes off the power curve below 1,300 psi on the rifle’s built-in pressure gauge – a gauge, by the way, that is large enough to be reasonably accurate.
In the next report, I’ll try to finish the features and get on with shooting.
