1.Hell, I would use a range rod (or something similar) and a common steel hammer. Wear leather gloves and get mad at it
2.Your doing it wrong! You need a near full bore rod. Solid. Weld a t bar to it.
3. Stop right NOW! First, kill the powder charge with water. Remove the nipple and flood the chamber.
4. NO! This is a Minie. Pounding it down will spread the skirt and really get the bullet wedged in against whatever it stuck on. Then it will be harder to pull out.
5. You can try compressed air but being it's stuck half way, I don't think that will do it but it's worth a try. Your only other option I see are to use a bullet puller or get a grease gun fitting that matches your nipple threads and then pump out the minie with a grease gun.
6. Or remove the barrel then the breech-plug and shove it’s ass out the way it came in.
7. not a good idea on a musket without the correct tools.
8. I gues a bench vise, giant crescent wrench and leather pads won’t get it.
9. Remove barrel from rifle, rest breech plug on block of wood to protect tang and beat it down with a BFH and a section of 5/16 All Thread wrapped in tape to protect the bore if you can't get a better rod.
10. No Read posts 9, 10 & 12 !
