I'm new at reloading shot shells and I had a brainstorm. I want to make a good self defense round using a combo of slug and 000 buck. Does it matter what is in the wad as long as it can handle the weight of the load. Example, using a wad for 1 and 3/8 oz lead shot recipe but using equal weight of slug/buck. Does anybody know if that would work? Here is my recipe: Fiocchi plastic basewad fold crimp 26.5 grs of 800x powder Rem. SP12 wad 3, 000 buckshot 1, 20ga .125 card over pellets and under slug 1, 7/8 oz Foster type slug Crimped Any thoughts?
