Im after some advice from the guys on here Im not sure if this is whats known as tuning or if it comes under servicing, but I guess it doesnt really matter.
Ive bought a S/H S410 (in .22 but I cant see that making much difference) and Ive got a chrono so Im planning on testing it with a few different types of pellets to see what sort of FPS and ft/lbs Im getting. Im not sure of the guns age, it looks a few years old but reasonably well looked after. So first off, what sort of numbers should I expect if its running well?
Second, if its below par (and what would constitute below par?)
