It's all garbage. I will do You the favor of disposing of it for You....LOL Just watched a guy pay $50 US for a bandy of 1945 GB Mark 7. It was all clean, but I remember buying these for $5.00. Guess I picked the wrong time to start collecting .303's again....
BTW..S&B is ok. I have been having great luck with Privi brass. seems thick like Federal brass. No issues with squashed necks or case head seperation. I would shoot once and the recycle.
