I had a problem getting my velocity to go above 250-260 for about a month. I tried changing out the internals piece by piece, different air sources, barrels, paint, everything. When I finally figured it out, it was the velocity screw. Apparently, the stock powertube had stretched around the threads on the screw for some reason. The air blow by was so miniscule, you couldn't tell. I put a different screw in from a 98C and presto! 330 fps. Thought I would throw it out there since I haven't seen it mentioned before.

Basically, the screw and/or the power tube was stripped. Since I was updating the rear bolt and valve anyway, my resolution to the problem was to replace the tube. Funny thing is that it came with a new screw, anyway

A friend of mine is having a simular issue getting his velocity lowered. he says it won't shoot below the 320 range, and i really don't wanna play with him if i can't get his to lower to a safe speed. any clue as to why this would occur?

Spartan,
What kind of marker, whats his air source, etc. I've encountered alot of 98s that couldn't get under 300 in the past couple years. I have never figured it out but I'm guessing that its got something to do with the valve. Other than the velocity screw, it's the next thing that directly affects velocity. If the spring is worn, it shoots low so if it sticks or is bad spring with too high of a sring rate, one would assume that it would shoot hot. I could be wrong. Check all the o-rings, springs, etc. If it's e-gripped it could be the dwell setting. I have zero experience with them, but I think thats how they work.
Is this the same friend that you mentioned the other day that had low shooting problems?

hope you turnned it back down to like 280-290fps because 330 is kind of high. Glad you got it fixed though!

chronoed his gun today and i was able to adjust it just fine. I think the guy who owns it just didn't know what he was doing thanks for the advice guys

Yeah, I turned it back down to 285
