Of the main 5 or 6 rifles we shoot the most, Hodgdon/IMR powders in 4350 and 4831 lines will shoot pretty good. I've yet to load one of our rifles with 4831 and not get a 1.5" or better without much effort. That being said, I've had better accuracy with the RL powders in the magnums with the exception of the .300 Win mag which will shoot a 200 gr Partition sub MOA with IMR 4350.
So maybe powders are like bullets; they'll all do the job, you just gotta place the shot?
