I tried SB6.5 briefly in my 7x57 a while back (just a hair more powder capacity as a 7mm-08 Ackley), and it was definitely VERY "glitchy". I got nowhere near the listed Hodgdon max loads or velocity before I was getting obvious pressure signs; case head swipe, sticky bolt lift. ES/SD were horrific as well (over 100 FPS spread), and I was using WLR Mag primers, so I don't think I was under-powered primer-wise, LOL. Maybe it works better in a Creedmoor or a 30-06, but I kind of gave up on it at that point and haven't messed with it since.
If you have't tried it already, you might try some Varget in your 7mm-08. I was pushing 140's around 2850 FPS at a grain under Hodgdon's listed max in my 22.4 inch Tikka, and it was the most accurate load I found for it back when I had that gun. I'd bet you could comfortably get a 150 up into the 2680 to 2700 range (Hodgdon and QuickLoad both agree), and would have quite a bit less temp sensitivity than you got there.





Sent 15 rounds with the Shilen 30-06. This is a composite score from 3 groups of 5, and overall I'm not too unhappy with that. 168 Tipped Matchkings, 51 grains of Varget in Win brass @ 2844 FPS average for all 15 shots. I was getting a LOT of velocity deviation - 58 FPS ES/ and 14.9 SD, so I am fairly confident this would have been better if that was not so wide a spread. Next time, in the Lapua brass should tighten that up.
I still am not thrilled that all I've gotten to shoot well in this rifle so far are matchkings, but I'd at least hunt with a TMK in a pinch, where I would not with a SMK. 165 Nosler's will be my next test, and then I'll see if I can get this gun to shoot in a lighter stock I'd be more likely to take hunting than this Magpul thing (dam, it heavy).
