I understand fully what you are saying, and I do use faster burning powders like Accurate no. 5. A faster powder is typically going to have higher pressures at similar velocities, and they just can't keep up with BD or other slower burning powders like A9. I have tested several dozen distinct workups with 6 different powders under numerous bullet combos in 10mm. BD groups like an absolute champ in my G20, and it is a very good performer when I feel like getting some higher velocities.

So a bit of muzzle flash that is imperceptible in the day is just more of a side note than a problem.
