Today, we’ll test the Walther 1250 Dominator at 50 yards. I had to go out to the rifle range for this test, and we’ve been having some winds lately, so it took some time before I got a calm day. But this day was perfectly calm — I couldn’t have asked for a better day to shoot an air rifle at long range.

As you recall, the Dominator takes a 300-bar fill, which is 4,350 psi. I had to delay the test to get my carbon fiber tank refilled, and even then I didn’t have enough air for a full fill. When you fill a tank, it gets warm; and when it cools back down, you lose several hundred psi. I was able to fill to about 4,100 psi this time, but that single fill was enough air to last for the entire test, which was about 50 shots. And the needle in the pressure gauge is still in the green, which means there are more full-power shots remaining in the rifle. read more

Let’s look at the Walther 1250 Dominator accuracy at 25 yards. In deference to the 8-shot clip, I’m shooting 8-shot groups rather than 10. The way this rifle loads, with the clip almost disappearing in the receiver, it’s too difficult to keep track of those 2 extra shots.

It’s loud!
I’ll be honest — I stalled testing this gun in the house because of the noise. It’s one of the loudest airguns I’ve ever shot indoors.

Air use
I said last time that I would give you a shot count once I filled the rifle to 4,350 psi (300 bar). Well, that didn’t happen. I filled it as far as my freshly filled carbon fiber tank would go, but that was only to 4,200 psi on the tank’s gauge, which seems pretty accurate. The rifle’s gauge showed a lower fill pressure, but I chalk that up to small pressure gauges never agreeing. read more

Thank you for being so patient with me on this Walther 1250 Dominator report. I had to suspend it while I was back in Maryland; but now that I’m home, I can start up again. Today is velocity/power day, so we’ll learn a lot about this air rifle.

Filling with air
To fill the reservoir, you first remove it from the rifle by unscrewing. Then, it’s screwed onto a brass adapter that’s screwed into a 300-bar DIN hole on a carbon fiber tank or scuba tank valve.

You fill the reservoir up to 300 bar, or 4,351 psi. The only way to get that much pressure is to use either a carbon fiber tank or to connect the reservoir directly to an air compressor or hand pump that goes that high. My carbon fiber tank was holding less than 3,000 psi when I conducted this test, but fortunately the rifle has a broad power band. Even though I can’t fill the reservoir all the way, the gauge on the tank still reads in the green. I’ll get fewer shots, but they will be at the same velocity. It’s just like a car that goes no faster when its gas tank is full or nearly empty. read more

“A poor man’s PCP!” That’s what “they” said about the Hämmerli 850 AirMagnum CO2 repeater. It has many of the features shooters were looking for — repeatability, accuracy and a huge number of shots from the 88-gram CO2 cartridge it used. So they called it a poor man’s PCP; and before long, someone converted one from CO2 to air. They liked it that way, and a boutique industry was born.

But Walther, who makes the Hämmerli 850, was paying attention. If people wanted the rifle to use compressed air, they could build the gun that way from the start. The result — today’s test report on the Walther 1250 Dominator. read more
