What caused a torn case?
Was out at the range to day with my M4. I put about 300 rounds through the gun flawlessly, then i had a misfire, i pulled the charging handle back to chamber another round and it only when halfway in. I removed the upper reciever and bolt and found an empty case still in the chamber. My first thought was that the chamber was dirty and the case stuck, but when i sent the cleaning rod down the barrel the case fell right out without any effort. I've had stuck cases tear the rim before but this case was literally torn right in the middle. After clearing the stuck case i put another hundred rounds down range without any problem so im assuming this is just a defective round, anyone see this before? It is Federal American Eagle 5.56, which i believe is military over-run m193. Case is headstamped LC 05.
"The budget must be balanced. The Treasury must be refilled. Public debt must be reduced. Arrogance of officialdom must be tempered and controlled. Assistance to foreign
lands must be curtailed, lest Rome become bankrupt. Citizens must again learn to work, instead of living on public assistance."
