Question about Kriss Vector 10mm brass damage....

[DirtyDave]

So I bought a barely used Kriss Vector 10mm and took it to the range, shot fantastic. But when I picked up the brass every single round has the mouth bent a little. I called Kriss support and they said this was normal. OK, not happy about that but will deal with it.

My question is has anyone figured out why this is happening? Maybe some high speed video footage?

Thanks, David.

A dinged case mouth is the norm for all my auto-loading guns, rifle or pistol.  Ejection is a violent process and guns are designed to be reliable, not preserve brass, which is viewed as a consumable.  This isn't a problem to be solved, but a function of reliable auto-loading operation in high pressure cartridges.

Although all my auto loading guns don't rough up the case mouth, I would agree completely with Sqlbullet. Small dings or slightly bent case mouths are no big deal in autoloaders. They usually resize just fine and aren't an issue for reloading. The only time that I would be concerned is if the damage to the case mouth came from the front and was compacting the case mouth into the case wall. That's the sign of poor ejection and a possible ejector/extractor issue.

My Kriss does this no big deal really and as others have said it?s violent process ejecting spent cases. The Kriss does it a little differently because of the bolt travel slow motion video will solve the reason why. By the way I really like my Kriss Carbine
