The writer spends a lot of time on ball vs stick powders. I don't know that ball powder should be to blame, maybe they used the wrong ball powder. I've used ball and stick powder interchangeably in my match ammo and from published literature they have similar burning rates, the ball powder I've used is manufactured by Winchester so they could have used an appropriate powder back at the time.

I've read before about powder residue being a factor in cartridge extraction, the gist of it was that a different powder had different additives and left different residue in the chamber. We all know that some powders are "dirtier" than others, that could explain extraction problems. And extraction problems are still a thing, even using stick powder.
