Ha, since the wads can't be use more than two times(damaged the four side wings) and could stuck inside barrel, and the paper sealing not possible to reuse. I cut out the side wings on the wad and use two insert in a shell with 12 bbs in between, that works well. And can be kept using for a while, save some money!
this way will reduce the shooting range and power
Side note: I have feelings this shotgun could be...... if someone report it a RS?
