Basically got an old vulcan a few years ago, and myself and a more mechanically minded mate had a go at recondtioning it with new spring, seals, e.t.c., and reblueing it (looked pretty good for about a week ). Anyway I have this as a 'backup', and is currently on loan to a mate who has helped me get alot of my permission, for shooting rats about the farmyard at close range.
However he now fancies coming rabbiting with me, but i don't think it's powerful enough.
So is there a basic test i can do to estimate the power, without a chrono? If it is less powerful, is it worth taking t
