First, were you swabbing the bore between shots? Wet patch then dry patch then new load. ie was the barrel fouling responsible for the PRB getting hung up?
Next, why two patches? One patch should be more than sufficient. I have double patched balls, but only when I was in a pinch had has some very thin patches available and then only to finish up a match.
When a ball is stuck that close to the muzzle, dribble in a little cleaning solution of oil to soften the fouling around the patch. A few drops can make it much easier to pull out. A T handle cleaning rod gives extra grip and strength to pull balls as well.
I still occasionally dry ball a load and have to do something extra to get it out. I've tried just about everything. Even pulled breech plugs.
