Have a look at
http://www.southwestammunition.com/. Very accurate and very consistent. The stock comes and goes and there's time when you have to wait for your order (sometimes several weeks), but they've hired some new people and I think things have become faster.
I've shot their 175 SMK in a Magpul class with my SR-25 (a little faster twist than yours) and it was fantastic. At least half the class was shooting the same stuff and everyone was very happy with it (for those of us shooting .308).
