Website fps varies greatly based on if they're going off manufacturer estimation or testing themselves.
And if they test themselves, it's dependent on that gun. That's why ehobby had 100fps variations on springs.
Easiest to got M150 and cut it down, but safest to just get an M130

Novritsch makes M140 spring for his SSG-24 that shoots about 490 fps new and once worn may shoot about 480.
I guess cutting a M150 is just trial and error. There is no formula, cut x amount of coils to reduce x amount of FPS?
