playing around with my excal and LPR settings. Had it set at 55 psi and i left it to do somthing else. Came back about a minute later and the gauge read 50 psi...... Fired the gun several times lpr back to 55 psi. If i let the gun sit for awhile i will have a low first shot. Watched the gauge it will slowly bleed down. I'm guessing i should call aka and get a replacment seal or 2. Any clue what the prob might be? Thought lpr core?
