870 express, 3in ejector sheared rim of shell. HELP

[shawnbostock]

took a nice deer down today, racked new round,when i unloaded i noticed the round that chambered came out with a notch sheared backwards, the exact width of the ejector, brenneke black magic 3in slug, i have never had issues with this round nor the gun. i dont notice a difference about the ejector visually speaking. i have not been able to duplicate. dont know if it was just a bad round? its like a can opener peeled it back to a 90 degree angle.

One of shooters had such a problem on one of my trainings:


Usually, that happens with reloaded shotshells and rough chamber. Polishing chamber may help.

I assume you're talking about the extractor, not the ejector.

Had the torn shell been fired?

[shawnbostock]

yes that is what i meant. sry we had a death in the family so i have been posting when i can and not been 100 percent here mentally. it was not shot.

Steel-based shotshells can hang up in chambers after firing, usually due to some combination of poor ammo quality, excessive internal pressure (if a shell was not loaded correctly), or a rough chamber. However, if you had an unfired shell stick so hard that the extractor tore through the rim, and you've used that same load in your gun previously without any issues, it's a strong indication that that particular shell was simply defective.

Weird... unfired... had to be a super thin base or something. If it was a full strength rim you'd have to work pretty hard to rip through the rim. Since you said you noticed after I'm assuming you didn't notice a problem upon initially running the action.

I have the same issue with hornaday slugs. They don’t always have to have been fired.
