If its so bad that nothing works, remove the breech plug, get a long driver bit and wrap tape bushings around it. Drill out the center (CENTER! make bushings!!) and it'll give the lead somewhere to go when you push/force it out.
It aint pretty, and if done right you wont mar anything, but as a last resort it definitley works.
1/4" is good, 3/8 bit is PLENTY.
