I don't believe a TP smaller than 3.0mm ever works in a 12FP springer....

I've had great results with only a softer spring in the Vulcan. The heavy piston and the narrow transfer port seem to balance out nicely.

I've had great results with only a softer spring in the Vulcan. The heavy piston and the narrow transfer port seem to balance out nicely.

The shot cycle on the Xocet is quite horrific as standard but as I said I seem to be getting good results just by removing weight from the piston, 273grms is heavy, I’ve also been able to reduced preload as a result, currently running pretty much smack bang on 11, hoping to lose a bit more off of the piston yet whilst maintaining 11’s…
