Questions and answers
Shell casing stuck in handle where firing pin is located
To remove a stuck shell casing from the handle of a Remington 476, users report that the casings can get stuck and may not eject regardless of the method used. However, one workaround involves fabricating a firing pin from a Ramset nail and washer to improve tool function. There is no specific removal method detailed, but careful manual extraction or disassembly may be required. Caution is advised.
