N/A Lightened Piston

I thinky you better study air gun dynamics, heavier can be better, as a heavier pellet or a lighter spring,it is all about harmony

What do you think this thread is about? It is about the differences made by adjusting the equipment used it is not the end all be all of what is best

Sorry,I did not explain right.The heavier piston can be better at tuning down harmonics or damping the shot cycle; a heavier pellet does a little of this, as does a lighter spring....for every effect, there is another effect; that is why I used the word harmony. Each one of the things I have mentioned has some effect on what you want to achieve; how you go about or how you choose to go about it is what your outcome will be.
Do you want to have control of the outcome? That is why a study of air gun dynamics can help to figure out how and why things are done in such a way, also how you influence them by choosing the methods to do about the change you want to achieve.............

It's more a case of shoots not so bad than shoots so well. I made the gun heavier with a laminate stock and hw98 barrel and use the ARH low power kit for hw80 and a slightly tight Vortek piston seal. I don't like the firing behavior of my .177 30 very much

Thank you for responding. To each their own . I'm opposite. I don't like shooting big heavy guns. Even off a bench. My 97 and R1 get the least use of my rifles. My 177 Hw30s the most with my 177 Hw50 next. I like a quick clean snappy shot cyle. On a bad recommendation I ran a 128 wire Vortek kit in a R1 and it was about 12-13 fpe IIRC and the shot cycle was lazy two step process. It was more a ker thump than the single snappy thump I like. I've heard of people getting them to run well at 12 fpe but always wondered how to move that much air with quick clean cycle without enough spring to push it well over 12fpe. I imagine opening the TP would do it but I hesitate to mess with TPs due to the complexity of retuning them to original size. I've also heard of people sleeving them down to a smaller piston. I could see lightening the piston might be helpful to in 12fpe 80 platform.

There's so much stuff you can play with. It's definitely interesting stuff and I thank you for your input.

Be well
