I'm with you Red. Lots of folks think casting bullets is as easy as falling off a log. Well.... it isn't! To do it correctly, is a learning process, and even so-called experts miss the boat all too often. I've seen store-bought ammo which were perfect looking, but underweight because of internal voids. I tried casting for a few months, and just gave up! I think I saved a lot of frustration doing so!
Alan you are correct, that casting takes lots of trial and error to find the right mix of ratios. I only make shotgun sabots(LYMAN), but I finally found a ratio that worked with equivalent to bearing alloy of aluminium/plumbing lead. When mixed properly they cast properly,with only an average of a 25 grain sacrifice.😀
After casting 200 sabots, now it's time to try out loads that can give me usable group at 60 yards. Oh my shoulder is already saying nooooooooo! 😮
