Any of the older Lyman Cast Bullet handbooks are good, as is the NRA published "Cast bullets" by Harrison. It's out of print of course but Amazon's used book sellers usually have it available for reasonable prices. There is little new about bullet casting that the old guys didn't know.
I agree with ya that the old timers know a lot about bullet casting and such but I was asking because all the reviews I've read concerning the Lyman manual complain about it only covering loads using Lyman molds and only have a select few load data tables for certain powders. I'm the type that tends to read tons before I spend a dollar. I insist on getting the most for my money and I will research for months before investing in anything I want to last a long time.
