For clarification, the pictured group was posted by Beluebow, not me. As I stated in my comment, though, that group looks remarkably similar to one I fired while doing my seating depth tests. The Sierra accuracy load that I used for that testing wasn't a fast load. If memory serves, the Sierra manual lists it at around 2700fps (I don't chrono my loads when testing seating depth).
I don't remember exactly where my final load with Retumbo came in at (and I don't have access to my notes at the moment). I want to say it was 63ish grains. I will have to get back to you in the fall when I am home and can get to my notes.
