I bought a Lee 90028 18-Cavity #4 Buckshot mold on eBay back in June of 2020. That's like, last year. So long ago. $58.36 delivered. (Not to brag, but that mold, if you can find it, now goes for $124.12 plus tax from the same seller....)
Anyway, I have not used it yet. Got it all scrubbed, lubed with 2-cycle oil, smoked, and with handles, ready to go.
What's best for buckshot? Hard lead? Pure lead? Wheelweights? Range scrap?
Should I coat with graphite (and where do you get a supply of graphite??)
Does it matter?
Thanks.
