The only issues I remember about the older ones was Hornady brass sticking. When switching to another brass the problem went away I was told. I was also told that Hornady's brass was too soft. I thin Hornady has remedied that as well as I've been shooting some of their brass in my Lapuas without issue.

The Mossberg Patriot has 3 lugs? I wasn't aware of that. Thought it was a standard two lug design.
