Post subject: | Case rupture question? |
Shot my mosin today at 100 yards. This red army new ammo lacquered case got stuck in the chamber. Took me about ten minutes, and finally got the bolt open. I hope its not a headspace issue. It shot okay after that but shells were harder and harder to extract. I've been trying to resize the image to no avail. Its about a half inch crack, all the way through, just below the taper. Thanks for any input. Eli |

A dimension somewhere is out of spec. You could try a chamber cast to see how bad it is. A former owner might have fed the rifle bad reloads and sprung the chamber. SW |

....I may be admittedly ignorant on the subject but in any Mosin I've shot,the good ol' brass surplus and it has been great with no issues...as soon as I switched to lacquered (in same rifle) I had similar sticking problems......and I've got 550 rounds of 1953 dated Polish lacquered on stripper clips waiting on range time... ....have read eleswhere to take a chamber brush on a drill and ream it clean....havent tried it yet... |

Maybe you just got bad steel case ammo? I don't have experience with the lacquered stuff. SW |

Cleaned up the chamber with a 30 cal bore brush and hoppes number 9. It looks ok. Ill go shoot it some more next week, with brass case only. Thanks for the responses.Eli |

Sticking cases is not a sign of bad headspace. As you discovered, the issue was the lacquered cases. |
