Opinions, experiences, first hand knowledge and suggestions for spring, piston seal and/or tune kit for HW95 .22cal. Want the best if both worlds meaning a smoother shooter but don't want to lose power either. Hoping to stay in the original power range of 13-16ft/lb area I believe that they are from the factory.
Put in a Vortek or Macarri parachute seal correctly sized. Manufacture a fitted delrin spring guide & thin top hat bearing.Polish spring ends and lube with ultimox 226 threw out. Smooth Mother !!! having factory power or better.

I have seen/read that I want the piston to fall under it's own weight but stop when covering the transfer port. Is that too loose? What is your take? Thank you.

Thank you.On those actions with precision honed compression tubes ... what i will call a shaker fit.With a light film of lube on tube walls & seal, held vertical the piston will hold under it's own weight and not slide.Upon shaking tube this has piston slowly moving down, stop shaking it also stops.Ideally when set up this loose, manually sliding piston up/down stroke distance at NO TIME should you feel it get looser !!tad snugger ok because this will wear in over time & use.* if in doubt better to start a tad snug and let action break in, than start loose having chances of compression losses.
