BSA - That is a good question. That testing and those graphs were done 4 years ago, and I can't recall what my thinking was at the time. In the end, I went with a different bullet and different powder, so there was a lot more testing done than I reported at the time, so something came up which made me change directions, but I don't remember what. Due to a major construction project, I had to clean out my reloading room, which means my targets and notes from that time period were lost.
