StoneChimney, Will look at your site tonight, thanks. From what my Barnes book claims, the RSAUM & WSM with 165 X bullets in 300, the difference is a little over 100 fps. I wonder why you don't hear more about the RSAUM or at least I don't?

reynolds, ya I know but AR-10 is 22 inches and about the limit without getting myself knocked off the 4 wheeler so I'm resigned to losing some fps. I've even thought about getting a custom stock for my 30-378, like a youth size and then mounting 2 point sling, but still that 26 inch mark V barrel is too long for riding.
