26 Nosler signs of pressure

[Blueprint222]

Christiansen Ridgeline. 26" shooting off the shelf Nosler 140 Trophy Grade. They crono at 3220.
Used this ammo for the break in.
I'm getting occasional heavy bolt lift and seeing the marks on the head. I've put a total of 60 through it.
I know the 26 Nosler is a hot rod but I didn't expect this.

Definitely overpressure in your rifle.

Quit shooting it and send the rifle back, you've got problems.

I've sent Christensen the pics. Will try to call too. Thanks for the reply's...

3220fps is not a real stout load for a 140 in a 26, either you have some real soft nosler brass ( possible as lots of it is pretty soft) or you have a really tight chamber/neck.

Do the rounds chamber easily in it?
Can you fit a bullet into the mouth of a fired case?

The bolt needs to be pushed forward with moderate force.
I am able to fit a bullet into a fired case with little friction.
