- Go to the hardware store and get some JB stick weld.
- Take some stick weld and make it into a ball the size of the base of the cartridge.
- Shove ball of stick weld into broken case, try not to get any stick weld on the chamber or feed ramp.
- Wait 30 minutes for stick weld to harden.
- Take cleaning rod and push it down the barrel from the muzzle end until it rests on the stick weld.
- Take a hammer and lightly tap on the cleaning rod.
- Broken case will pop out with 2 - 3 taps.
- If case doesn't come out with 2 - 3 taps, give it a few harder hits.
Sometimes the JB weld will get knocked out instead of the case but this is very rare. In this case, you will need to cut a lip in the base of the broken cartridge then try again. Broken shell extractors rarely actually work. The case isn't actually stuck unless you've already banged on it with a chisel or something stupid. The case is just in an awkward position to get a good grip on it to get the case out.
