Just an update on this.
I had the red spring in (strongest) for when I was playing at 280 fps (pump not getting stuck).
When I tried playing at 230 on the novice field with a bunch of guys, I had to turn the TPC all the way out (counterclockwise) to get it to shoot 230 fps (this is when the pump handle starting getting stuck).
I switched to the weakest spring (blue). Then I turned in the tpc to about 3 turns and it fixed it.
Mike was nice enough to give a quick response:
"The causes for the pump to stick: Pump is twisted, bolt rod bent, return spring is missing, blot / hammer dirty, pump ID dirty. But in your case it is probably the internal velocity is turned to the lowest setting thus the hammer bolt connection when in a cocked state are kinking to the point where the mechanism is dragging in the breech, just put about 3 turns on the velocity adjuster, which is the normal position. If the velocity adjuster is moving out of position just tighten the nylon set screw in the side of the bolt. If the set screw won’t turn, remove the velocity adjuster, unscrew the velocity adjuster, file or sand the tip flat and reinstall."
