I have a 25cal wildcat. Holds air fine no leaks but as soon as I start shootings starts leaking air. Seems like it’s coming from the breach area. Any input would be helpful so to know where to start. Thanks Steve
In other guns that usually a bad or missing breach oring. If your speed is down on chrono that’s a sign. If you don’t have a chrono. Put a tissue over the breach area and see if it blows off . If so install or replace oring.
