  • Summary

Boy — do I have a good one for you today! It starts out looking bad but just wait. Today I test the accuracy of the Webley Mark VI CO2 Pellet Revolver with a 2.5-inch barrel.

A LOT of readers are watching this report, because this revolver touches a chord in most shooters. It’s very realistic, and the firearm it replicates is a classic. Ugly — yes. But a real workhorse! Here we go!

The test

Today I shot the Webley Mark VI CO2 Pellet Revolver from 10 meters. I shot off a rest, using the sandbag to steady both the butt of the pistol grip and my two hands. Yes — BB shot this revolver with a two-handed hold.

I cocked the hammer for each shot to keep the stray shots to a minimum. And the hold I just described was rock solid.

I shot 10-shot groups at 10-meter pistol targets which is asking a lot from a handgun with a 2-1/2-inch barrel. Not that it can’t be accurate. But the sight radius (distance between the front and rear sight) is so short that ANY small deviation results in gross movements downrange. You’re going to see that as this report progresses.

I thought I would test the accuracy with the same three pellets that I used in the velocity test. More on that in a bit. Let’s see what she’ll do.

RWS Hobbys

For no good reason I started with RWS Hobby pellets. I loaded six and then four the second time. I know that the cylinder revolves clockwise when I’m looking at it while loading with the gun broken open, so I know how to load those last four pellets.

The first shot hit the target — well, let’s talk about it. I squeezed the trigger and the revolver didn’t fire, so I thought I had put the safety on. But I hadn’t. So I went back to shoot and I squeezed off the shot before I was ready. It is a flier that I circled for you. The other nine pellets went into a group that measures 3.625-inches between centers, and shot ten opens that to 4.059-inches. Ugh! That’s a horrible group, not to mention that it’s somewhat to the left of center on the target. Oh how I hoped that the next two pellets would do better!

Webley Hobby target
Ten Hobby pellets went into 4.059-inches at 10 meters, but without the circled wild shot, there are nine in 3.625-inches. Double ugh!

Trigger pull

I have no idea why that first shot was so hard to pull off, but after that the revolver settled into a fine consistent trigger pull. There is a little creep in stage two, but it’s quite manageable.

Sig Match Ballistic Alloy

Next up were ten Sig Match Ballistic Alloy (made from tin) pellets. I sure hoped they would do better!

They did! Ten pellets are in 2.803-inches with eight of them in 1.853-inches. Now, that is better, but the pellets are still landing to the left of the centerline on the target. Okay, I thought, I will show you how to deal with that when you are shooting fixed sights.

Webley Sig Match target
Okay, now we’re doing better, if not good. Ten Sig Match Ballistic Alloy pellets went into 2.803-inches at 10 meters with eight in 1.853-inches.

But BB — I like those two that hit in the center of the bullseye! I want them all to do that. So do I, but that’s not where this revolver wants to put this pellet. Those two are actually stray shots. They’re not fliers, but remember what I said about a short sight radius being extremely difficult to shoot? They are an example of it.

And pay attention to what I just said about “this pellet.” Because a different pellet may go to a completely different place — as you shall now see.

Build a Custom Airgun

The good news — Ta-Da!

The final pellet I selected to test in this revolver today is the Air Arms 8.44-grain dome. For some reason I felt this might be a good pellet for this airgun. And it was! Oh, ten shots went into 3.515-inches at 10 meters, but eight of those shots are in 1.775-inches. And look where seven of them hit — in the center of the bullseye! Ha-cha! We’re on a roll now!

Webley AA dome target
The Webley Mark VI put ten pellets into a 3.515-inch group at 10 meters with eight of them in 1.775-inches. Yes, that includes the one shot outside the bull on the upper left.

Wow! This is great, because it means that this revolver is accurate. AND, it will make a better shot of you because of all the attention you have to pay to the sight picture to get good results.

Changed my plans

What I had planned to do was show you how to deal with fixed sights when the gun is shooting away from the intended target, but these results made me decide to do something different. I decided to shoot one last target with this pellet and just a cylinder full of pellets. In other words, six shots. Could I put them all in the bull?

Last target

On this final target I took great care with each shot. But when I was done only four of the six had hit the bull. Apparently I was tiring out. I shot six into 2.285-inches with four in 1.301-inches. I’m never going to shoot a gold dollar group with this pellet revolver through anything but chance, but this is superb accuracy for a pellet revolver like this!

Webley AA dome last target
On the last target the Webley put six into 2.285-inches with four in 1.301-inches.

Whaddaya say?

I don’t believe that this is the last time I will test this revolver. I want to try other pellets and also to (hopefully) refine my sight picture to do even better. This girl can shoot!


This isn’t the last you will see of this pellet revolver. It’s a great lookalike that is also accurate. It just needs a good shooter behind it, which BB will try to become.

  1. BB,

    The short sight radius really puts a demand on the shooter to concentrate on his sight picture to achieve accuracy. I wonder if it would be practical to make a front sight extension to demonstrate how much easier it is to shoot with a long sight radius? Then again it would be simpler if there was a long barrelled version to compare with.


    • Siraniko,

      There is the 6 inch version over here /product/webley-mkvi-co2-pellet-revolver-battlefield-finish?m=4482#8744 and if I were interested in pistols that would be my choice.


    • They also have the four-inch version.


      I myself would also prefer the six-inch. Hopefully they will get it back in stock soon and if I should win the lottery, which I never play, I will buy all three.

    I would love the challenge of finding out why this pistol or any did not put 10 out of 10 in the bull.
    I would check the barrel for any play, bore irregularities or its ability to rotate in the pistol. Need to correct that. Use the same shell in every cylinder hole, shooting six pellets out of each of the six holes keeping track of which cylinder shot where on the target. Shoot slow enough to make sure the cylinder is seated on the barrel and not still in rotational movement or bouncing back and fourth from play. Do it again with 6 different shells, one at a time.
    This would show if the barrel, one particular shell case or a cylinder play, bore / alignment the barrel is the problem. The pistol would have to be ridged in a vise, eliminating the shooter and every pellet would have to be exactly the same in size and weight and changed to find which type of pellet works best in the barrel. Also measure each pellet speed to see if the hammer, air valve is consistent. And obviously done in a controlled environment.
    A lot of trouble. May be more than one item causing it and you would have to replace parts till you found perfection, if possible?
    Worth the trouble? Not really, unless you had to or had good reason for doing so, but I think it is possible to identify the cause of inaccuracy…. Eventually !
    Unless, one or more parts are simply not manufactured to a tolerance that permits it.

    • Bob M,

      I would not do that with a real pistol with this short a barrel. That is plenty accurate enough to hit a man in the chest at 25 yards. With practice, that can be improved upon. I used to carry a Colt Cobra. In most home invasions the range is only about five feet. This thing was designed to be mean and nasty at close range.

        I agree with you. It isn’t so much with this pistol. I just brought up the subject because it would bug me if I had a an accurate revolver that was capable of putting 10 shots out of 10 in the bullseye and two missed …Exactly why did they miss? Was it me, the pellets or the pistol?
        I would want to know the exact reason so I could correct it. If it was important.

        I did something like that to the Hellraiser Hellboy. Only it was the opposite, 2 ‘Hit’ the bullseye, 6 missed and two did not even hit the target. Turned out to be the barrel. Replaced it with a Crosman 2100 rifled bb/pellet barrel and things got much much better. Even the FPS had a dramatic increase. That was one I had to look into or the airgun would be a permanent wall hanger.
        And that’s much worse then the gun safe queen ( I mean collectable ) it is today !

  3. BB,

    Whaddaya say? I say I would like to see more out of this pistol.

    I would really like to have all three of these pellet pistols, most especially the six-inch.. I guess I will have to see what I can do about that.
