well you don't give much detail there!!
is it new or 2nd hand? what hopper are you using? what rof is it set at? what is the LPR pressure? are you sure its chopping (is there paint on the bolt) and not just bad paint barrel match? Is it chopping lots or just one ball or so a day?
If your using a revvy and its set high rof you'll easily (and i mean easily) out shoot the revvy and depending on the lpr setting and brittleness of paint depends on whether you'll chop.
Bit more detail would help!!
