I have an unregulated FX400 which provides 60 shots at full power (JSB 18.1 gr, 890fps, 20fps ES) and am considering a regulated Bobcat. My 22 Cricket provides 70 shots at 860fps with a 10fps ES. I frequently use the medium and low power settings and do not know what I would experience with shot strings at the lower two power settings. Any data or comments would be appreciated.
