Hello every one, new to the forums here. Been reading awhile and learning. In June of 2021 I purchased a FX Dreamline Classic in .22. Then in December I found that the tank was leaking. Contacted FX USA. They were great to work with and sent replacement o-rings. I installed these a couple days before Christmas. I've shot about 1000 pellets out of it since. Last week got the gun out to shoot and the tank had started to leak again. Would like to know if I'm doing anything wrong that would cause this. I never go above 230 bar and store it at about 170-175 bar. Is this common? I use a Hill MK-4 pump and shoot JSB 18.13 pellets. Thanks for your guys help and knowledge.
