Hi, I just did the mod to my prod and my shot string looks like it keeps increasing linearly. I am aiming for 40 shots with about 12 fpe.
Heres what Ive done to the prod so far:
drilled 7/64" transfer port
Stiffer Spring (L: 1 11/16", OD: 5/16", Wire Dia: .041)
4 Harbor Freight O-rings
Any help would be appreciated. Thannks
Here are 2 examples of my shot strings, I noticed that around the lower fills fps starts spiking.
HThrow: 1 CW
HSpring: 4 CW
