I've been searching for a while and I've had no joy. I'm looking for some specifications on the Hw35, something's tickling my interest.

Does anyone have the Piston weight for the hw35.

I know it is a variable, but for a .22 how many mm of preload would you need.

Again, I know there's variables....
How have people found the differences between, the leather seal, synthetic and O rings.....More/less preload from one seal to another. And if piston weight had to be altered?

Thanks for your time, sorry for been vague.
Andy
