Dented case necks?

[hotshot828]

I have a win. Model 70 push feed bolt action rifle. When ever I extract a fired case the case necks have a dent at the mouth. I don't know if it is a bad ejector or something else?

It is more than likely that the ejector spring is strong and makes the case mouth hit the side of the action just ahead of the ejection port. Pretty common event. If it was mine and it is a hunting rifle, I would do nothing. A good positive ejection is good in this circumstances. I keep a round center punch beside my reloading press to straighten out the dent if I should get some of these. Just push it into the case mouth before running it into the die.
If you feel you need to mitigate the problem, you can shorten the ejector spring a small amount. But if you take too much off, you stand the chance of leaving the fired case laying on top of the follower.
Or slow down your bolt movement to the rear. The faster you pull the bolt back, the harder the case mouth will hit the inside of the action.

Thanks for the info

You can easily prevent the denting by taking your index finger and put pressure to the left on the case as soon as it moves a little to the rear. Maintain the pressure to keep the round from hitting the action until it is fully in the ejection port. May take a couple tries but it's nothing complicated.

I had the same problem with my Tikka T3x. Since it's a range rifle 95% of the time, I removed the ejector plunger from the bolt.
Now the empty cases stay on the bolt face and can be picked off with a fingertip. No more picking up brass off the ground, and no dented case mouths.

Lots of BR shooters remove the ejector and/or the ejector spring to stop this.
