Hi Peter. I think you're confusing Seyfried with Sherman Bell. He did extensive load testing on short 10s and published some of it in The DGJ years ago. I was shooting a short 10 at the time, and corresponded with him about the loads, utilizing some of them for my gun. Some were target loads and some were buffered bismuth loads. I killed ducks with them in AR back then.
Maybe someone could reference the back issues that contained the data. It would take me quite some time to look back through all of mine to find them, but I will if no one has that information available.
