So what is wrong with Alliant!

Am still thinking about the meaning of BERB,

Berry's Bullets

With some other digging around, and, thanks to Hornady's reference, I found some load data that started me at 6.3g if I recall correctly. Berry's says to load their (copper) plated bullet as you would a FMJ type projectile so long as the velocity is within their specifications.

Appreciate the info and feedback.
