Hi, been a while, had to sign up again as I’ve been out of the air rifle scene & the forum for a while.
Anyway, I’ve got a Webley raider 2 shot in .22 & use a pump to fill it. Recently it’s not filling to 200 bar, maybe getting to about 150. And then after about 10 shots it’s seriously lacking power & dipping shots badly.
Ive checked for leaks after a strip down & cant see any damage to the o rings & ive done a balloon test to see if any air is escaping.
Im at a loss now to be honest & ive just got a new permission to shoot !
Any ideas & help would be much appreciated.
