I have one anything other than the rubber rounds is 5 rounds check out the aluminum balls there the best ammo for this launcher the increased power makes up for one less shot
yeah, the slider moves over to the slot where it locks open to load and dumps all the balls out. With 5 balls it does not move all the way over. I'll post a video of what was happening. This is the marker that Amazon would not let me return. Not a total loss since I can use it with 5 shots.
