Gamo Piston seal

New Gamo 33mm Vortek seal installed.

1) its not as hard and "plasticy" as the original.
2) it went on a little easier than the one I bought from spain
3) 40 shots in it is consistant so far, in about a week I will know more

I don't have a chronograph but FPS per "drop" @50 yards seems very very close to the original.

No complaints so far 🤪
I am getting 1/4 to 1/2 inch groups @27 yards, very consistent after about 200 shots.

I'm glad your getting good results and hopefully it get better. What model and caliber you have.
Gamo swarm Magnum 10x gen3i in .22, I have 2 of them, both with a Vortek seal now. Now all I have to do is find a loading mechanism for one of them. Had to take it off to load manually. It doesn't push the pellets all the way in and shaves them off a bit when I close it.
 
My Gamo Hunter Extreme .25 was shooting FTT 20.06g @ 885fps and now 760fps. It destroy the breech seals I replace it twice on both guns.(Swarm Magnum 10X GEN3i). I sand the edges on the barrel latch and hopefully that helps. Bad piston seal or breech seal or both.
