Today we look at the accuracy of the Dan Wesson 4-inch pellet revolver. As we do it may be helpful for you to keep in mind the fact that I have also tested both the 8-inch Dan Wesson pellet revolver and the 6-inch Dan Wesson pellet revolver, so you have something to compare today’s test to. To see those tests, go to the product listing I linked to and look for the link to the review/article. Let’s get to it.
I shot from 10 meters, resting my hands on a sandbag. I’m shooting just 6 shots at each bull, because that is how many cartridges the gun holds. I sighted-in and also shot the first group with 7-grain RWS Hobby pellets. All shooting was done in the single-action mode (where I manually cock the hammer before each shot). There were no bad shots in this test. Everything you are about to see happened with the sights in perfect alignment.
Sight-in reveals a problem
My first shot from the gun landed very low on the target paper at 10 meters. Obviously I needed to adjust the rear sight up, which is where a problem occurred. When I turned the elevation screw counter-clockwise, it came up but the rear sight leaf remained down. There was no spring under the leaf.
What I did then was adjust the rear sight screw as high as it would go without coming out of the gun, then I shimmed beneath the rear sight leaf with a small piece of card stock that was folded over many times. I then screwed the adjustment screw back down to put some tension on the card stock, so the rear sight leaf wouldn’t move.
I’m sure there is supposed to be a spring under the rear sight leaf, but the test gun just doesn’t have one. My fix with the card stock is a good trick for you to learn, so here is what it looks like.
Shot number 2 landed almost as high above the bullseye as the first shot was low, so I pulled the shim out and removed several layers. Then I inserted it again and screwed the screw down until it was tight again. The third shot landed about an inch above the bull and slightly to the right, so I removed one more fold of the shim stock and tightened the adjustment screw back down. The next shot was in the black, just above the center of the bull. By this time I had fired 4 shots, leaving two loaded cartridges in the cylinder. I put pellets into 3 of the empty cartridges and loaded them into the cylinder. I now shot the remaining 5 rounds from the gun and then checked the target. There were no more sight adjustments in the test, and I was counting the first shot after the final adjustment as the first shot of this group.
First group of Hobbys
Okay, now we can talk about the first group. There are 6 shots in this group, but I want to show you the entire target first, so you can see where all the pellets landed during the sight-in. As I told you, the first shot was low, shot 2 was high and shot 3 was almost where I wanted it. Shot 4 landed in the back part of the bull, touching the red center, so I decided to consider it as the first shot of the group. Unfortunately one of the subsequent 5 shots landed close to the third sight-in shot, so I had to indicate that last sight-in shot on the target.
The 6-shot group of Hobbys measures 1.422-inches between centers. One of the shots strayed out very close to the final sight-in shot, so I indicated on the target which on was the sighter.
Qiang Yuan pellets
Next up were the Qiang Yuan Training pellets that I thought might be the best in this revolver. Boy, was I wrong! Six of them went into 2.739-inches at 10 meters, making the worst group of the test. And, boy is my new right eye (the one that had the cataract removed) sharp! I actually saw that pellet that is way to the right in flight, and it looked like a major-league curveball! Looking at how the paper tears, I think this pellet is unstable in this Dan Wesson, and is yawing badly, so I don’t recommend it.
Sig Match Ballistic Alloy pellets
Next I tried some Sig Match Ballistic Alloy pellets. I probably should have shot some of these in the velocity test. They would no doubt push the velocity up over 400 f.p.s. In past tests I have found this pellet to often be superior. It’s the only lead-free pellet I have ever tested that is accurate, and sometimes the accuracy is stunning — as it almost is today. This was the second most accurate pellet of the test, with indications that it wants to be the best. Six went into 1.708-inches, with 5 of them going into 0.925-inches at 10 meters.
Crosman Premier lite pellets
The final pellet I tested was the Crosman Premier 7.9-grain dome. Six of them made a group that measures 2.041-inches between centers. This group is well-centered on the target and would be good to use on soda cans and the like, as long as they are close.
The Dan Wesson 4-inch pellet revolver has a lot going for it. The looks are spot-on and the gun functions just as it should. The realism is remarkable. Accuracy is okay, but not exceptional. The cartridges are easy to load and they come out of the cylinder with no problem.
I didn’t test the speedloader this time, but I’ve seen enough Dan Wesson speedloaders to know they work flawlessly.
Is this the pellet revolver for you? It could be, though if you need better accuracy, you might want to consider the 6 or 8-inch guns.
