It very much depends on the gun and fill pressure! My S510 is 288cc/250bar and a breeze to hand pump, giving 55 shots in .22 @ all settings. I refill it in 12 minutes with 2 mins being a rest for the pump/me. I would never get a compressor period if that was it...but, of course I dove in face first without checking for rocks at the bottomI feel the same way about break barrel airguns. I like to hit a quarter size target consistently at 60 yards and I can shoot each shot in less than 3 seconds without pulling the scope off the target. This makes a followup shot so quick to finish the clean kill goal. I have the advantage of being a lefty shooter so I can cock the pcp without taking my finger off the trigger area. Relax Hateful; I know you are a determined breakbarrel only airgun shooter.
