What are my options to squeeze more power out of my Webley Vulcan?

[abqjoe]

I'm looking for recommendations for aftermarket tuning kits for my MKII Webley Vulcan so I can squeeze more power out of it. Also, if I don't the install myself, who would you guys recommend for doing the work? Thanks!

ARH (Air Rifle Headquarters) has tune-kits, which are prolly geared for stock power, (which isn’t bad)

It’s ur gun, but if it’s shooting anywhere near stock numbers, I’d just enjoy it for what it is:
A handy, well-built British sporter with decent power.

Good luck!

It just needs a new main spring. My velocity fell off after 15 years or so. Got it right back after I put a new spring in it. If there is a way to get the gun shooting faster than the 830fps I think it is rated at, it will no longer be a very nice gun to shoot. 800fps out of an accurate nice shooting gun is better than 1,000fps out of a pellet flinging buzz bomb.

Thank you gentlemen, I'll respect your advice and just stick to stock numbers because it is constantly accurate as is. Thanks again!
