Currently got a BSA Buccaneer SE .22 a few months ago that I pump with an Air Venturi G9 hand pump. From what I understand, there are no desiccant packs/add-ons that will fit this pump. I am concerned about getting too much moisture in the cylinder that will eventually lead to it rusting out - especially since I live in the humid part of the Pacific NW. Does anyone have any suggestions on how to avoid moisture buildup when pumping?
