the stock was made by a friend. She is eat low speed, about 697fps with a JSB 14 gr, with about 80 shots. Have not figured out why the low speed, as did the whole process of tuning taught here in the forum

with 1800psi reg you should be getting much higher numbers and much lower shot count. Are you using the dominator spring and hammer?

No. I used different springs, but only made more low speed. I'll wait to open the store 850.

Installed guide, spring and hammer dominator walther and cylinder 22 cu.





The speed is around 740 fps with the 15gr jsb. I'm feeling down, what might be happening?
