I’m on my way down the slug reloading rabbit hole. For those of you shooting Lee slugs, particularly 7/8oz ones, should I be using pure lead to cast or would mostly wheel weights be ok? I’d like to use these for very close deer hunting if I can get a recipe to pattern well enough at 30-40 yards. FYI, I plan to use wads and HS-6, I have data for several combinations of wads and hulls to test. Appreciate your thoughts.
