Got some performance data for my new FX Royale 400 with regulator in 0.22 caliber. Looking for help to validate whether it is normal or whatever since I don’t have anything to compare it with. All shots were over a chronograph starting with of 220 bar; gun set on HIGH power initially shooting 16 gr JSB pellets. Velocity started dropping off after 105 shots and 140 bar. Subsequent shot data using HIGH/MEDIUM/LOW power settings is listed below. Accuracy at 25 yds is very good.
