In anything where it's appropriate, 2700 has always worked well for me. In big cases (Swift, bigger .17's, 243 Ackley's, etc.) the reduced carbon build up in the throat is very noticeable compared to other powders. In my standard 22-250's, it's never been that great for accuracy...a bit too slow, likely.
Like everything in life, just try it and see how it works.
