Any one ever ran these two powders against each other? I have a 375 project and I ran through my applicable powders (15, varget, imr and h4350, 16, & 17 and 16 is leading the way right now. As with most people I believe there is "more" to be had. I am wanting to try imr 4166 and N540 but don't have it and don't want to if it's not worth it. Anyways figured I would throw it out there to the masses.
