Thanks for commenting.
One thing I did notice (as it applies to felt recoil) is that, in this application, powders like Varget, RL-15, BLC-2, Leverevolution, and 4895 really increase the felt recoil without giving much advantage to velocity. Benchmark, which is what I settled on, is a little faster burning, produces more velocity with less powder than the others. I suppose 3031 probably falls into this group, as well.
I noticed the same thing between 4831 and 4350 when it came to the larger cases. 4350 got me better velocity with less felt recoil.
