I've read the Lee manual second edition. It doesn't list their lead bullets specifically because their data is just copied from various bullet and powder manufactures and not from their own. Cast data in rifles doesn't make much difference with regards to seating depth, but it's very important in handgun ammo. Lees truncated bullets should be tested in all applications, but sure no reason to test lees 230 round nose in 45 auto when it's totally fine to use Lyman's RN data. I'm about halfway trough Mike Venturinos articles and they are pretty decent. Overall I'm pretty satisfied.
