Does the middle pressure gauge suppose to hold pressure after use? I see it held over night and don't see a bleeder valve for it like on the output side.
If zeroed at 100yds what would you think the holdover should be? I tried shooting at 200yds with no luck I could hear the pellet hitting the plywood target hanger but no luck hitting target. I'm shooting a M3 in 25cal with JSB exact king 25.39gr.
