    Why does the Webley Vulcan behave so well?

    Heavy piston of quite large diameter, but it still behaves calm during recoil if set up with the correct spring.
    Is it just a good combination of stroke, diameter, piston weight and compression?

    the small port probably balances out the heavy piston.
    lighter piston and 3.0mm port would be a good test
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    Disturbing guns that work as well as my Vulcans is not something I want to start with...
    The recent threads about dream airguns has my head turning again... The Vulcan just suffers from short forks, which really is a shame.
    A Supersport has a much more stable barrel, even if it only has a pin like the Vulcan, but the barrel locks up a lot better.

    And then theres Micks recent work on the Diana 35, which puts his action closer to the Webley Vulcan specs.
    Maybe a modded Diana 35 really is the perfect sporting breakbarrel...

    With tight guides and some extra spacing it duplicates this kit: https://www.airrifleheadquarters.com...488/552850.htm

    I get around 11fpe in good Vulcans with this setup, some more in the .22's, and some less in the .177's

    Anybody know if the bore or stroke and maybe piston weight even was changed from the mk1 and mk2 as I had a mk1 which was one of the best hunting rifles I ever owned and took many many rabbits/ rats / crows etc but I just couldn’t get on with the mk2 I bought and gave up on it after a few month’s, both were .22.

    I have shot one or two Vulcans that shot beautifully at our Boinger Bash meets. Most notably Speedmaster's last year. It had been fettled; fettler unknown.

    I think it has so, so much to do with the spring. Not to be viewed as a "mere" piston propulsion component. Everything revolves around the spring......force unlocked, force cocked, force at point of piston bounce, preload, rate.

    I've had 2 & thought highly of them. Std from the factory & not messed with. I had the hinge pin converted to a bolt. Problem with the the jaws opening up solved.

    I do like the Webley Vulcan.
    I got my mk1 Vulcan in the early 80’s and still have it.
    The gun got a upgrade by way of a V-Mach kit fitted, standard spring with guide’s piston liner,piston seal,top hat.
    Much nicer shot feel.
    I replaced the barrel hinge pin to sort out the wobble,but it is still there to some degree.
    I will try and get a nice pistol scope to put on the Teleskan mounting block for old times sake.

    Who did the bolt conversion for you?, I have always wanted my one sorted for a better lock up.

    "I think it has so, so much to do with the spring"

    I agree, the spec of the spring changes everything and its the most difficult to quantify when buying replacements. Some "standard" springs from suppliers are not the same as the original ones fitted from the factory.
