There are two possible interpretations of what i THINK your asking me."Can you pump a Daisy Powerline 880 40 times?"or"Should you pump a Daisy Powerline 880 40 times?"Yes, you CAN pump it 40 times... but it causes severe internal damage to the gun's firing mechanism. It can cause the gun to malfunction and not work properly.
