Why does the Webley Vulcan behave so well?

[PCPShooter]

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?

yep ..

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.

The spring dampener was a milestone in spring guns imho.

Had a venom tuned MK1 back in 1983 and it shot very well. Mach 1.5

I have a webley vulcan mk2 Carbine venom tuned at webley , it’s a stage 2 tune what ever that is . It shoots very well

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.

Of course the spring plays a large part, but it you wont find a spring that solves basic balancing problems.
When stroke/piston weight/piston diameter/transfer port are properly balanced, spring selection just becomes that last ingredient.
What I'm trying to say is that Webley got it right with the Vulcan, perhaps even better than we have seen in many more praised later springers.

I've been fighting the TX, several HWs etc for a long time, but with a good example of the Vulcan, it is just easy to get balanced, linear, soft recoil without any major alterations of the action.

Tony is still in my possession though for how much longer I don't know seeing as I've a tx200hc and tx200sr both in. 22 which I shoot more now. Also the sport 127 isn't getting much use either. I would like to have been at this weekends bash but I had a prior engagement which meant I couldn't go. That was stopped as I had an operation planned for today on my right shoulder which was cancelled as I tested positive for covid on Tuesday which has left me feeling bloody awful and totally fed up as I've been waiting for the op since before the beginning of covid.
