Lets say I buy the Hatsan Blitz at .30cal... And lets say that the Blitz needs aprox 300 pumps to go from 120 bar to 250... A filled Blitz at .30 will give 100 shots filled to 250bar... So if I just want to shoot 10 or 20 pellets only... I would have to pump ±30 times for 10 and ±60 for 20 from 120bar? Or because it is low pressure it gives less shots per pump meaning I would need more pumps for these 10 or 20 shots? Thank you
