This stuff was sold to me as seconds in boxes of 500. It has different head stamps, with different dates. Some of it looks perfect. Some has small dents. Some of it has stained brass, as the last picture shows. That was the worst I could find in a box of 500. I shot 60 of the worse I could find tonight with no problems at all. Cycled and grouped just like brand new. 2000 rounds for $1000. If you only want 500 it's $275 for a box. This is the best deal I've found on .223 in months.
