Thank you posting these pictures. I have followed along with your media tests and thought you had tested the Gold Dot/Deep Curl.
These really show what I am trying to say with the electroplating process that bounds the lead to the coper.
They make these bullets just down the hill from here in Lewiston, Idaho. In the old days I use to go to the Speer plant (ATK/CCI) down there a lot to watch the process an to observe some of their static testing. Plus at that time you could buy 'seconds' from them that were really good for target practice and plinking.
But even in those early days - i always felt that Seirra made the better bullet - but the Speer plant sure was handy.
