a cursory look of Load data on one of the sources showed that AA2015 powder did the same work with quite a bit fewer grains of powder than the other choices.
400gr bullet, 10lb gun. The differences in starting loads:
With aa2015, 67gr, 2258fps = 48.6 pounds of recoil
With Varget at 75gr, 2365fps = 55.3 pounds of recoil
This is a measurable difference, however, if I was to spend an hour looking at all data sources I'm certain I could find an even lighter recoiling option at appropriate velocity. 4064, IMR3031, and RL15 are typically mild-recoiling powders if appropriate for the caliber that I always investigate. H4895 I almost never use, even though it allows you to use reduced recoil loads, at any given "normal" grain weight it produces more recoil than many alternatives.
