Pressure you dont have to worry about. You change that when you chrono it, so that will always be a variable. Set your dwell properly though according to the sticky. That used to be my lucky body and I could get it to cycle at 5 ms dwell, but it would be completely inconsistent. I used a dwell of 12 on that body. And with an L7 bolt, that should run just fine for you as I am sure the finish on the bolt is better than the GCPB bolt that I used (you have that too).
Even if you can get it to fire with a dwell of under 12, I would not advise it because you would lose consistency, and thats just no fun. If playing in the cold as well, up your dwell a few clicks.
Don't hesitate to PM me if you have problems with it.
