The same Nosler brass that the Kimber Hunter bolt won't hold is held tightly in every other Mauser action I have. My Kimber classic grips them tight and my ruger grips them tight. There is a issue with the brass being out of square if you will. but the fact that the Kimber Hunter will only hold the brass when rotated to the right spot tells me there is a issue still with the gun. Picking up some hornady brass tomorrow to tryout. If the bolt will hold them properly then I will buy a bunch of hornady and start loading them. If not then I will just sell the gun.
