Me too! Whoever gets them first, please make that observation your first posting. My prototype rounds of a couple of years ago we're made from Hornady's Prototype rounds (Yup, they have Hornady's name stamped on the head, and sport large primers in them.).
Just a note, of FYI.. You might think the reason Hornady uses a small primer, in our 450b, was to keep the Bench Rest Guys happy, they simply love small primers, for small groups, and if that are your thoughts, you'd be right. However that is only a planned-for, side effect, one in which we see every time we shoot, but the major reason for small primers, is to give the Web-Area, more strength and it does this very well. Having said that, I for one hope they are large primers, just for the plethora of choices we'd have..
