I was going to build a 6.5 06 myself and have a CF2 action here ready to go … but then I watched a youtube clip comparison with the 6.5 saum. With the same powder charge the saum gave much better velocity than did the 06. A more efficient case design. The forum thread on 6.5 x 47 is very interesting from a case design and efficiency point.
