I have the Lyman books but they're for metallic cartridge. Round ball is pretty straight forward but conicals I could use some info on. Thanks, James
Good books for casting ML bullets?

Hi James,
The modern day references are hard to come by. There's the Lyman black powder handbook as a source but it's limited in the data provided, especially in the more recent editions. Decades ago they did a much more thorough, much better job of it.
Page 265 of The Muzzleloading Caplock Rifle (Ned Roberts) provides a chart titled "Table of Twists for Small-Arms Projectiles by Major J. P. Cundill, R. A." that does a good job of laying out length of bullet in calibers versus length of twist in calibers. It's pretty neat to see what people were doing in the mid 1800's. That old book has a wealth of knowledge in it to show the researcher what works and by implication what doesn't.
There are also some down right sophisticated twist calculators offered on line. I've got a simple one I downloaded from somewhere that works just as good for my purposes but are they better than Major Cundill? Nope.
