OP listed the powders he has... but didn't say he wanted to know what others use, within that list of powders.
I know high velocity kinda wears out barrels so....
I use RL 7, both 4198s, H 322 occasionally.
But more commonly, Unique, Alliant Steel, Blue Dot, just to name a few.
All work within the ranges I'd use that kind of bullet for...while preserving barrel life.
Slower and long barrel life, is more important to me that a fast velocity and shorter barrel life.
