So I'm long in the tooth, and opinionated. But lately I've changed my favorite powders.
New powders, to me that I'm very pleased with, include:
TAC (1st, best new powder for me) similar to IMR 4064 in burn rate, but EASY to load and is my goto powder in several cartridges. Highest velocity in several cartridges.
RE26, (in fact a bunch of Ramshot powders)
H4350 slowly replacing IMR 4350 due to temp sensitivity.
H4831sc replaced H4831 100% due to ease of loading and can put more powder in the case. (H4831, IMR4350, and H4895 were my first three favorite powders - H4895 is still a favorite.
What say you what are your new powders.
