I use the H&G 51GC bullet in my Ruger Security Six 357; it's a 158 gr SWC bullet with gas check. For business loads I use 14.5 grs of W231 powder. But now I'm looking for a softer load, about 3/4 or 2/3 throttle. Anyone have a good one that gives nice accuracy? I'd prefer the following powders: Unique, AA#5, or 2400.
