How does this thread apply nearly ten years later due to powder shortages (Unique comes to mind) and the plethora of alternatives to the old standby powders (BE, Unique, 2400)? These are for 158 gr generic cast SWCs in a Ruger 4 5/8 inch Blackhawk:
950-1,000 fps - getting by nicely with W231
1,000 - 1,100 fps - N340, Accurate #5, BE-86
1,200 fps - 1,250 fps magnum - still 2400 is king for me loaded with 13.5 grs
If I had to choose only three…
Fast - W231
Medium - N340
Slow - 2400
