I'm shooting a 350mm .25cal leshiy 2 with bottle added. Was wondering what ideally the best speed to shoot at or reg pressure to start with. Current tune is about 4 mags before its down to 100bar. I didn't set the gun up so I know nothing about where the reg is. If 4 mags is good is typical I'll leave it be. Ill get fps when my pellets arrive tomorrow. I know the few mags I shot where moving hot and accurately. Currently I shoot 25gr jsb what little I had that is.
