Why is the HW95 so bouncy??

[BTDT]

In an old AGW, I think the article was about short stroking, there is a picture of you Jim, where you have a pock holed 95 piston sitting on a set of scales, I can't remember the weight of this piston off the top of my head, I think it was a lot less the 270g, did you abandon the lightened piston and go for reverse engineering upping the weight or is 270g the standard 95 piston weight ?

I'll need to plough through my old articles and notes to be certain, John, but I do remember first reducing the weight to match the sectional density of my 25mm HW77 (249g, being piston, seal and top hat), then taking it down to 238g.

My conclusion was that, to reduce recoil, reducing piston weight was preferable to reducing piston stroke.
