Got gas in the tank and went outside to test with 800-850psi this is what happened:
Vid was shot one handed, old paint and velocity just a little too high. I shot it next to my AXE and the Epic is now shooting too hot. I turned it down after the vid and it shoots beautifully.
I'm not going to discount all the breaking down and relubing of everything, but obviously the tank output pressure was the culprit this time around! I'll just keep my tank pressure here since the Axe's reg can handle it anyway.
I shouldn't have assumed that my shims were in the tank.
Anyway I'm up and running now and I can't wait to hit the field with it. Anyone with Epic questions hit me up anytime. I cannot for the life of me contact Jim and there's not near enough information out on the internet on the Epic. I'll be making plenty of videos including a video based user manual.
