After the first seasom of hunting with jacketed slugs for the 45-70. I read an article abour how easy, cheap, and accurate cast slugs were. I've accumulated a half dozen molds over the years and have never shot another jacketed bullet thru either of my 45-70s.
A 405 or 445 grain air cooled cast bullet brings down a deer at most any range that you could see still the animal. I've never had leading in either rifle, but then I size the slugs .459.
Since I make my own, I don't have to worry about anybody else's production.
