Got a HW80 in .22 was very smooth to shoot but out putting out 13ftp, so have resprung it and as on U tube didn't use any grease on the spring (one that came out had heaps) so now I have 16ftp and a hell of a twang. So dissappointed was hoping to get 20ftps. 
See a different type of spring with a square section steel design, sounds the bees knees https://www.trademe.co.nz/a/marketplace/sports/hunting-shooting/air-guns-parts/parts-accessories/listing/3826514078?bof=f8Mf7Uzm would this be an improvement in power & smoothness? Or else where do you Guys get the tuning kits from, and what price landed NZ?

seals all good on it?
What pellet are you using?
Have no dought that you'll get some pretty good advice from ppl who know on this site.
I'm less 20fpe on the tx and can pop a hare out to 55m. Poms pop them out at 70m on 12fpe.

From what I have read 18ftp is probably it, so I'm there, just wish it was not quiet so harsh.(would greasing the spring settle that?) Amazes me what the Pom's do with 12ftp

From what I understand it does. I've greased the spring on the gamo, just a light smear around spring. No lumps or clumps.
piston as well.
TX will get it soon as its just started that twang sound. As I haven't touched it since I brought it, I'm guessing it's due.

Have you tried a heavier pellet in it?
you might find it likes the extra weight when firing.

Need Mike to comment, he is an ace at problem solving. Did it have the spring guides? I forgot to put them back in on a gun after a rebuild and it's sounded like a church bell after each shot.... Another option to try is put a washer in behind the spring to give it more tension/pressure (some people call the power washer etc...)

Has a inside spring guide.
Doesn't have the outer spring sleeve like the Vortec kits have, can see how that would stop the twanging.
