Motor is EG 1000. The gears have a normal ratio.
By playing around with the TM spring and a Prometheus ms110, it's clear the TM spring is a bit larger and doesn't slide smoothly inside the piston. That might be the problem.
Should I put the PDI 140% back in, but cut a few coils away? Or else I'll need to order a stupid 300 fps spring from HK.
