I don't reload but I do like to shoot my revolvers. Lately I noticed most ammo for 38 SW is now 125 g vs 158g. Why ? I know one of my revolvers says something about the round needing to be at least 125 g, so I figure it's a problem in a 357 round. I also talked with a guy at the range that claimed the 125 g SW shot 4" low thru his guns. Any insight ??
