I know I've seen some where, maybe this forum, about using a punch to cut your own wads. I found some info using a search both here and elsewhere. What I'm wanting to know is: What do you use for a punch, for say cutting wads similiar to wonder wads, 12 gauge? Did you make your own punch? I though I read somewhere, where someone sawed off an empty CO2 cartridge, ground it with a dremel and used that. How about gasket punches, will they work, what size? Isn't 12 gauge, equivelent to .750? That would be 3/4" right? That would fit almost perfectly then in a 12 barrel. Would it be better, if cutting felt, like maybe 1/8 thick, to use a punch a tad larger like a 13/16" size? Thanks for any help you can provide.
