Hey I have a question. I just got my gun back from the store today from downgrading the spring. I needed it to go below 380 fps so I got an M113 spring for it. However, right after the new spring was installed, I had the gun chronoed at 376 average BUT there were a few shots that actually went 381 to 383. Is there anyway to weaken the spring a little more to wear it down so that it won't go above 380?
