I also did an idiot load today. Must be something about the 4th of July.
I have a .54 Hawken, and on my 12th load today I rammed home a .535 ball on .018 spit lubed pillow ticking patch, but I had forgotten "first the powder, then the patch." [forehead slap].
Fortunately, I was able to extract the ball using a screw-threaded ball puller I had the foresight to buy at Bass Pro Shop near Richmond, VA a couple of months ago. I then had to use my patch puller to get the patch out becaue it didn't come out with the ball. I screwed them both onto the end of my ramrod with the ramrod tip removed.
After screwing the puller into the ball, I clamped the end of the ramrod into my Black & Decker Workmate bench, gripped the rifle stock, and pulled with all my might to get the thing out. I had to get my wife to sit on the bench to keep it from moving. It worked, thank goodness.
Did you try clamping the ramrod into a bench vise or something similar and pulling on the gun?
Good luck, and I hope neither of us does that again.
