From what I understand, Jerry is looking at not only the BR group, but the position shooter as well. There are also some "tactical" type guys who would like a rimfire action that will drop into their 700 stock and have the same feel. It's these that will be repeaters.
As for better accuracy, I can't see Stiller putting out an action without carefully considering the current offerings and how to improve on them.
For those who are 40x nuts, this is gonna be the ticket.
As for the other detailed questions, I'm not sure of the answers. Give them a call. I don't want to mis-quote Jerry.
I was busy watching Jerry and Curtis field some crazy questions from the Shot Show people. They also had quite a few of their centerfire actions there, and I was getting my fingerprints all over them as well.
