This video explains the theory behind our heavier 410 shotgun slugs.
Up next is my recipe for the .410 slugs I make. Please do not altar these recipes. This recipe is based on information from the third edition Lyman Shotshell book. My slugs weigh the same as a load of #9 shot in a Winchester AA Wad. The slugs and wads weigh 210 grains combined. Please do not attempt to shoot the 210 Grain .410 slug from a choked barrel.
I make no money from the sale of products listed below unless you want me to make you some slugs.
