Make sure that you "rock and cock", meaning that you tilt the marker forward to allow the balls to roll down the feed tube. This is especially important if the tube is not full. Also, if you don't have a detent ring kit then when you cock the ball could be rolling out the barrel without you noticing. If you don't cock all the way, then you won't be able to fire at all, so thats not the problem.
