I was shooting my Emag today. Velocity was way down after changing all orings and taking out shims. I turned the velocity nut until the it was in the 270-280 range. Once it was there, I didn't check it anymore and I went to town on an old piece of plywood. I think I went through 4 hoppers on the tank before the gauge read 1k psi. At this point, the valve started venting out of the left side hole like crazy. Never had that happen before. I've searched the forum with little to no luck about this issue. Any advice is greatly appreciated.
