Walther 1250 Dominator PCP air rifle: Part 3
by Tom Gaylord, a.k.a. B.B. Pelletier
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.
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.
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.
I didn’t get a complete shot count. I did, however, fire about 40 shots in the test and still had air remaining for at least another 15. If you can get the gun completely filled, there have to be at least 55 full-power shots available. Probably more, but at least 55.
I mounted an AirForce Airguns 4-16X50 scope on the rifle in a BKL 1-piece cantilever mount. The scope was low over the receiver, even though the BKL mount is a high one; but because the circular clip is entirely contained within the receiver, there was no interference.
I shot from a sandbag rest at 25 yards off an MTM Case-Gard Predator shooting table. In a moment that will become important to know.
I sighted the rifle in and started shooting with the H&N Baracuda Match pellet. It was accurate enough, but I felt the rifle could do better. Eight shots went into a group measuring 0.597 inches between centers.
The Baracuda Match pellets didn’t give me what I wanted, so I switched to 10.34-grain JSB Exact Heavy domes. They started out doing better than the Baracudas and produced a 0.522-inch 8-shot group. But two pellets strayed from the main group. I called the one that went to the left, but not the other one that went high. So, as good as this pellet is, it isn’t the best pellet in this rifle.
Then, I tried RWS Superdomes — a pellet that many of you favor over just about all others in .177 caliber. And this is where I had an epiphany with this rifle. The first 8-shot group measured 0.461 inches, but it was full of wild shots that went off when I wasn’t on target. That was both the fault of the trigger and the rifle’s light weight. I’ll address it in a moment. But this target told me that this rifle could shoot much better if I really tried.
The Walther 1250 Dominator is a very light rifle, and the trigger isn’t that light. As a result, the gun moves more than a little as the trigger is squeezed. This can be overcome by paying extreme attention to detail on each shot, but it’s something I normally don’t need to do when shooting an accurate PCP.
That’s why I mentioned the shooting table and sandbag rest. Normally, such things are an absolute lock for the guns, but this time the rifle is so light that it still moves around too much. You’re only going to solve that with technique.
The next group was shot with as much concentration as if I were using the artillery hold. And the payoff is a 0.404-inch 8-shot group. That represents the best I can do with this rifle and pellet at 25 yards.
The bolt is hard to cock and sticks when pushing it forward to load the pellet. It isn’t much of a hinderance, but you do notice it. I did discover that if the bolt is worked fast and with authority, it does become smooth. So, the rifle likes to be treated like an SMLE.
Opinions thus far
I found things to criticize on the Walther Dominator 1250. No. 1 is the need to fill it to 300 bar. That’s just too much pressure, and it uses all the air I can get. The rifle is very loud, and I’m no longer used to pneumatic air rifles being so loud. The trigger is too heavy and long, and the rifle needs to weigh at least 2.50-3.00 more lbs. to be stable. However, all that pales when we look at the accuracy.
This is an accurate air rifle — make no mistake. Today’s test was at 25 yards, so it’ll be very interesting to see what happens when we move to 50 yards.
