2Late I was at the range this evening trying some Winchester factory 158gr JHPs in my 50th Ann. .357 Blackhawk. I am not having much luck using cast in this gun but these JHPs did somewhat better. I loaded ten each over 12.5 and 13.5 grains of 2400. The lighter load put ten shots in about 2.5" and the heavier load put nine shots in 1.5" with one flyer about an inch out. I shot these at about twenty yards over the hood of my truck with a breeze behind me.
Didn't have my chrono with me so I don't know what they're doing. I think I still have room to go up a bit more plus many other powders to try.
