Np03 tune question

[RBD2]

So the np03 .22 I have I'm useing jsb 13 grain pellets I'm shooting on high and only get like 10 shots within a 30 fps extreme spread from 200 to 150 bar then gets to almost 80 fps different.

Looked and the hammer adjustment seems to be backed out all the way Counter clock wise. I would assume turning it increases velocity . Wouldn't that give me more es and less shots?

Open the transfer port in the barrel to 13/64" and the power adjuster and valve to 3/16". A stiff single spring or a twin spring debounce hammer and you'll double your shot count and lower the extreme spread. The last one I tuned was 24 shots at 900fps with 18gr. Should do 36 shots at 850 with 14-15 gr.
