This is .243 brass and has been reload 8 times. They have been neck sized only and I check the case length and trimm as needed.
What are the rings around the case neck caused by and should I keep using this brass?
I didn't notice it until I started reloading the Berger 95gr vlds. This was the first loading with the Bergers.
Could it be a sign of over pressure? This is a max load and I did get slight ejector marks on a few of them.
+1 Chamber is what I was thinking tooIt could be signs of pressure but if you want to make sure Get on line and google Brownells
and order some cerrosafe.
Follow instructions and make a cast of your chamber. If there is reamer marks or rings in
the chamber It will show you. Lower pressure loads may not force the brass into shallow grooves.
The best way to check the chamber is to use a bore scope with a 90o mirror but they are
expensive. (Unless you know someone that has one).
