theoben say
Max energy & shots per charge from a 280cc bottle filled to 232 bar (3200 psi)
.22 12ft/lbs 300 shots .177 12ft/lbs 220 shots
so at 130 shots you should still be fairly accurate so you may have a problem with the bottle seals, best to wait for a post from some one who knows more about pcp guns, theirs a few good uns on here who will give you good advice
