I'm getting 3030fps with 69.0grs of Winchester WXR and Reloader-22 and 3010fps with 65.0grs of IMR-4350 using Hornady 165gr SP.Started getting pressure signs with 71.0grs of WXR and R-22,pressure signs showed up at 66.5grs with IMR-4350.I didn't have my chronograph with me those days,I was probably getting around 3100fps or so,but the pressure was too high.I backed down and she shoots great and I know I'm OK pressure wise.
