I might be getting a new permission for shooting pigeons soon. I thought using my Leshiy for the job as it is light weight and maneuverable. Some of the shooting will be inside so I need to turn the power down. My Leshiy has the standard after market Huma regulator installed, not the 12 ft lb. version. How low can I expect to turn down the power and get consistent performance and about what bar setting for the regulator. Thanks Bill
