As Pete says.
But it's so easy to generalise, as said earlier. Some guns might benefit from more piston weight, others not. It depends on the design, dimensions, desired power and characteristics etc.
In the case of the TX HC item, this longer / heavier top hat increases weight, and therefore momentum and also spring preload. Many tinkerers remove this heavy steel item and substitute for a lighter acetal item, giving very slightly less initial recoil from the first compression stroke and a "quicker" feeling cycle but have to increase preload to restore power as this usually drops, thus quickening up the cycle even more, due to quicker piston acceleration (lighter piston / increased spring force). That extra preload will also come into play to combat potentially greater piston bounce displacement.

All what you say is right Tony and I don't have that piston weight in my gun but one of the reasons that it come out was because the power was too high, I only mentioned it because I thought it was an example of a heavy piston not robing power not how the gun shot, as far as I know all of the high-powered springers have heavy pistons. I do get that the UK power limit tunning is an all-round balance
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

I have an after market hw80 piston, weight is 425g has a 22mm I/D Not that i use it as such
That is a bigun ! My pistons are usually around 150 gms
