When I use 4064 anymore (and I do occasionally) it's the Accurate Powders version, which is short-cut. Haven't tried it in the Swift because I don't own one anymore, but it worked well in every other cartridge I've tried it in, with very similar results to IMR4064 without the hassle of log-sized grains.
But based on previous experience with IMR4064 in several Swifts I can't believe it somehow beats a bunch of other powders, whether H414/W760/A2700, Reloder 15, Big Game and Hunter, etc. etc.
