Got my new crown yesterday.been running it over the chronograph here's what I get front power wheel on high. Reg 150 bar.hammer spring on max.and all I get is 750 fps with 44.8 pellet.help
I know my crowns I had to pull the stock off attach the power wheel back on and adjust the hammer spring on max until there was very little play…then after putting the rifle back together the tuning process starts. There is an older thread with a few videos attached.
