hk33ka1 --New rifle brass is neither FLS or fire formed. It is in some in between phase. No one really counts on new brass being real accurate first load,but FLS new brass really does help.
Just for fun try it once. Load 10 new and FLS 10 new. I think you will be amazed at the difference when you shoot them.
