I just bought a new rifle in 6.5 creedmoor. This is my second rifle in this caliber and when I shot it today I noticed bright spots on the rim of every case. Is this over pressure? It's the same loads I used in my other rifle and this never occurred. I'm using a 120 gr. nosler ballistic tip with 38.0 grains of Varget and a Winchester LR primer. Max load is 40 grains. The primer is not flattened or cratered so I'm not sure what to do. Any help is appreciated.
It could be.. Do you get the shiny spot just by closing the bolt on on a live cartridge? Is the bolt sticky or hard to turn after firing? Is the mark a surface mark or indention?

What rifle?
Maybe the case is not square with the bolt face...?
Rough bolt face?

Chamber and eject a round without firing of you can and see if it's due to part of the process there or something that happens when the round is fired ?

I just chambered and ejected a round and it did not do it. The bolt is a little hard to turn after firing but it's not real bad. The rifle is a Ruger Hawkeye Predator.
The mark is just a surface mark.
Since the fired round is "gripping" the chamber after expanding from firing, it sits stationary while the bolt rotates to unlock. The mark left is the steel ejector making a drag mark. The brass is softer than steel, so it will mar a little bit. The reason it doesn't do it with an unfired round is due to the casing being able to rotate with the bolt during feeding and extracting.
Since you are running reloaded cartridges, could the head spacing between the two chambers be a little different? I've see that before.
Other ideas: New rifle: Strong ejector spring leaving a mark?

It definitely amplifies the situation, not to mention the sharp, new edge on the ejector that will develop a radius after a few hundred rounds.Originally Posted by JMW4570
Thanks for the help I think yall are right I just wanted to make sure it was safe before I loaded any more ammo. I will drop back to the starting load and see if it still does it.
