Response to 1377 to 1322 upgrade, my results. Need stronger hammer spring?
On 15 pumps with the mods below I was able to get
1377 15 pumps - 750fps
1322 15 pumps - 650fps
lighter valve spring
heavier hammer spring
Didn't want to mess with the port
I had fantasies of getting 1000fps, somebody may be able to do it. I stopped and am happy with were they are. Acuracy is great and shot placement counts for alot.
Cleaning and oiling the barrel can get you abit more fps.
