How do you unload a muzzle loader? Besides shooting it.
“Pull the Nipple!”
Two ways, you can use a cork screw ball puller on a ramrod tip or pull the barrel from the stock, unthread the breech plug and tap the ball out. There’s old saying: “It’s not a question of if you ‘dry ball’ a load, but when”. Believe me, I’ve done it. A pain in the behind. “Powder, patch, ball”. Been building and shooting those old “assault rifles” for close to forty years now.
