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.

Re: Which 6.5 caliber to go with?

I have a 260, a 6.5-06, and a 264 wm. My favorite is the 6.5-06. They all shoot very well. However, the 6.5-06 is the most accurate: .5 moa groups are common. It has also turned in a surprising number of .25 moa groups. With H4831 and 140 Berger VLD's I am getting velocities around 2950 fps. That is with a 26 inch McGowan barrel. My 264 WM has a 27" Krieger. Using a max published load of RL22 it shoots the same speed. I found some old data for IMR7828 that puts the 264 in the 3150 fps range. However, accuracy suffers and pressure signs are apparent. The 260 is great and easy to reload for, but it gives up about 200 fps to the other two.
