One thing I've noticed when chronoing ANY gun is a good paint to bore match is essential if you want to have the +/- 5 fps. Old paint most likely has flat spots and isn't that round so that would be an issue I would address. Until you can get a good paint to bore match it's going to be tough to get a consistent FPS reading.
Started with a Splatmaster, moved onto a Nelspot 007, then came the Autocockers, then a STERLING Pump, next was a Bob Long defiant then a PM7. As of now I have 10 Sterling Pumps, 2 Phantoms for SC, a CCM SS-25, a PGP and a Sovereign 3.
