Huben Charging GK1 with Hand Pump

yeah. i am not 70. but after handpumping i am not in tiptop shape to shoot. to control breathing and heartrate definitely my out of shape body needs a break before attempting accurate aiming.
I sometimes take my .22 GK1 to matches. I shot both sub 12 FPE and at 30-ish FPE depending on the match. In both cases, I hand pump the little gun when needed.

My score does not get negatively impacted. Sure, I am not really competing in the first place, but still.

To shoot at 30 FPE, I need to charge from 180 bars to 300 bars, that's about 40 strokes using Huben's own pump.
