Hodgdon's Relative Burn Rate chart shows Lil'Gun (#62), then H110 (#63), WIN 296 (#64), IMR4227 (#65), then Power Pro 300MP (#66); Lil'Gun is the faster and 300MP is the slower.
I've been using it for my full-bore .357 loads for a while, I bought a couple of pounds when I couldn't find WIN 296. It measures more like WIN 296 and H110 than it does Lil'Gun, and gives some big velocities when loaded near max in the .357 pushing a 158 JHP. I like it fine, and have thought about starting at 18.5 grains for a 210 XTP or Berry's plated, for my M57. That would put it between the starting loads for WIN296 and H110 in the Hornady 10th Ed book. It's well below the max of either powder.
I found a post on the "other" S&W forum from 2012 with someone who's loaded for the .41M I don't know how to single out a post, but here's the link to the page, it's post #16, and he's the thread OP.
