Hi guys I'm just getting back into airguns in fact iv saved enough for a SPA PR900W 5.5mm. Now I'm on the hunt would rather support somebody wanting to sell to upgrade their outfit.
Anyway I'm doing research while I wait and am wanting to know what does fine tuning mean? Is it simply finding the right pellet to suit the barrel and gun or is there more to it? Thanks guys. So awesome to see so many guys enjoying this awesome sport and hobby.
