I spent the day prepping 220 rds of brass and will be ready to load when the bullets get here. While in the loading room I consulted Hornady, Sierra, Speer and our favorite, Gun Gack 1.
All the powders I listed in the start of the thread had listed loads with the exception of A2015. I'm going to replace that option with Varget. All are capable of 2200 + fps out of a twenty inch barrel. From there the targets and chronograph will make the choice as it usually does.
It's been years, but I always used 3031 in 30-30s. But FYI Accurate #1 Loading Guide from 1994 has 2015BR data for 30-30/150s starting at 26.1 gr @1929fps & max as 29gr @2192fps from a 20" bbl. The jug of 2015BR I have from back then (it was made in China) has been comparable to today's data in 22BR, 6PPC, & 358 Winchester.
