cocker efficiency

[Skeet]

planet set mine to just under 600 psi...
You might want to tell us a bit about it...can you hear any leaks, whats it chrono at..does it chrono consistently?
have you got a 9 foot barrel on it?!
listen for a leak down the barrel...

answer

No leak (as far as I can tell). The only thing that I have messed with is the back block screw to play with the fps, chrono is broke, so not sure what its firing at, if it is over 300fps it will only be by about 10 or 20fps, cant see such a dramatic loss in effeciency being caused by this, but I maybe wrong..

Its very easy to under estimate a markers velocity...trust me!!

What can happen, is that if the velocity adjuster is too far in, the hammer hits the valve very hard...combined with the wrong input preassure (which can change), the valve stays open longer than usual, which means more air passes through and is therefore less efficient. It doesnt necessarily mean that because more air is going through, you get a higher velocity, because that is what sweet spotting is all about.
you need a chrono, some good paint...or just someone to do it for you!

fixed it...

Well took it to Planet, problem was black magic reg was set to 150psi, (not 350 like it should be) and the gun had been crancked up to fire 300fps off this low pressure. This meant the velocity adjuster was too far in, the biggest mystery is "how did this happen", I am getting suspicious of the marshalls at a local rec ball place I go to, they never did like me using this gun.......

Told you it would be something simple!
Next time you go there...pop some Tippex around the inside of the allen grub screw in the bottom...just enough so that if they put a key in to adjust it, you will know!!
Then you can fcuk em up!!
