Gentlemen,
I was working on a AR-15 223 Wylde barrel that a 300 blackout round had been mistakenly fired in. The case head separated and the rest of the case was stuck hard in the chamber. I tried many things to remove the case but none of the usual tricks worked. Finally I plugged the barrel just ahead of the chamber with paper and poured some molten lead into the chamber from the back of the barrel. However I over filled it and got lead up in the locking lug area. So not wanting to damage this area in the barrel lug area I made a chisel out of brass rod and chiseled enough of the lead out that I could ram out the broken case and the lead in it with a brass rod from the front of the barrel. I then used a scratch awl to pick/pry out a lot of the lead in the locking lug area but not all of it is easy to get to so some still remains. My question is: has anyone removed this type of lead from a barrel using heat or something to desolve or loosen the lead so it can be removed without getting too rough with it? If so I would appreciate hearing from you.
