Trouble with FPS consistancy

[Skoad]

i have a mini with a classic 68 valve and a 68/4500 nitro duck tank.

Now when i went to the field to play last time (first time using nitro) i figured i would be +/-5 fps, but when i chrono'd at least 10-20 shots it was more like +/-15 or 20.

thats almost what igot on my co2 powered m98. now is this the quality of the reg on the tank or what?

What kind of fps do you guys get on what tank/equipment????

What tank are you using?

Have you cleaned and lubed up the orings in your valve? It sounds to me like you need to replace the Reg seat, but I am not very good at this type of stuff :D

Try replacing the reg seat.

I never really got good consitancy on my mag either.
