My Velocity on my velocity?!

Allright, I was setting my Fps at the place I play and my velocity was all the way up and it was shooting only 240-250 so i had to play like that . Before I had my velocity all the way up and it was shooting well over 300 something, what happened

One possibility: Your tank was low on air/CO2.
Or: an o-ring problem, possibly the O-ring on the end of the bolt.
Or: something between the tank and bolt restricting air flow, maybe a piece of crude somewhere in along the air path.

I've experienced the same problem and it was one of the first two choices.
