I haven't gone quite THAT light in my .357/38, but I do have a 356402 that throws just a tad large that scoots at a pretty good clip through the Ruger. Drops about 128gr on my alloy, if memory serves, and darned accurate, too. Long nose on it, so it seats a little deep in .357 to fit the cylinder, but I found swagging it into a slightly blunt HP does some nasty things over a full-house load. Couldn't give a velocity off the top of my head, but it's a serious whistler.
