I have a Remington 30-06 that has always shot pretty well. a lot of sub moa groups and a lot of low ES. Most of my past and best experience has been with Hornady brass that has been fire formed and neck sized. I have started to use some virgin Nosler brass that I did run through a full length sizing die before I loaded. I am seeing my groups grow and my ES grow as well. Has anyone experienced these type of results when starting with virgin brass? I would assume that the Nosler brass would be of higher quality than the Hornady but have not seen the positive results that I was hopeful for. Any thoughts?
