over powder/ over shot wad maker?

[Mr. 16 gauge]

Being a do-it-yourself kind of guy, I'm looking at my box of coco puffs this morning at breakfast and thinking "I could probably use this box to make over shot wads". I'm also thinking I could use the backs of old legal pads to make over powder wads. All I need is some kind of punch.....check a few web sites and few carry punches of this size; those that do want a small fortune for them!
Does anyone have a way to make them using some common house hold item as a punch? If I come up with something, I'll let you know......
Thanks in advance..........

Keep an eye on ebay. You see wad cutters on there quite frequently. Are you going to use them in a breechloader or a muzzle loader? Quite often you will have to cut the wads just a little oversize to make them work well. You can cut old wool blankets and stack them for filler wads and you can coat them with wax to make them a bit stiffer. Makes 'em coat the bore with a little wax. Never hurts to have a little wax in any shells. We used to wax 'em all the time..paper of course. Bores..actually chambers never used to rust at all with paper shells. Ah for the good ol days...NOT!!
