I saw a lb of Alliant Steel today for $7.95, so I picked it up with the idea that it might be useful for moderate 357mag and 45Colt loads. Using Alliant's "relative quickness" as a guide, it's a little faster than 2400 (27%) and slightly slower than Blue Dot (37.8%), both of which are useful for the 357mag and 45Colt.
Since it's closest to Blue Dot, I felt like I could probably take about the same charge of Steel for a given recipe and get slightly slower velocities.
For example, Alliant lists 10.7gr of Blue Dot for a 357mag 158gr JSP at 1400fps. I would start with 9.5-10gr of Steel and go from there.
For the 45Colt: 11.5gr Blue Dot and 250gr LRN for 890fps. With Steel, I would start at 10.5-11gr.
Am I on the right track or do I have a pound of powder that's of no use to me.
