7.5x55 case deformation

[dante_mags]

I was shooting my k11 for the first time, and it shot perfectly fine. Then I looked at the spent casing and I noticed that the tip of the case was bent inwards. I decided to cycle the spent round through the gun again to see what would happen. The case bent in again in a different spot, so it obviously doesn't deform when I shoot the rifle. Is this normal? The k11 ejects pretty hard so I'm thinking it has to do with that.

when it comes out of the chamber it impacts on the receiver somewhere as it ejects. Happens on some guns don't own an 11 so don't know if it is normal on that one.

Happens on all my 1896 based actions (G96/11, G11, K11) it is just something that happens when they eject. If you slow down working your bolt when ejecting you can avoid that otherwise it is just part of using the rifle.

You are pulling back too hard against the ejector. Ease up once the bolt opens and just kiss the ejector with the case rim.

Just checked my empty brass and no dents.

It is from forcibly pulling the bolt back when extracting. You will see a small brass mark somewhere on the top of the receiver, roughly case length away from the ejection port.

Its ok for berdan primed brass. If going to reload, then yank the bolt a bit gently and the brass will land right beside the left hand elbow.

My 96/11 and K11 would do that... I would just form it back with the pointy end of a 308 bullet prior to reloading.

The dents will generally come right out when you run the cases through a sizing die.
