All applicable warnings about loads being hotter than the load books apply to my load that I use for Cowboy Shooting - because it''s lower than anything I could find in the load books. A particular danger would be squibs that would leave a bullet in the barrel. Use this data at your own risk.
Generic 215 cast lead SWC, WLP primer, 5.0 grains of Titegroup, Starline brass trimmed to 1.275", COL of 1.585"
Note that I had quite a few short cases in the 500 I bought from Starline, so I trimmed them all down to a little shorter than standard so the lengths were all equal. I use Reddings Profile Crimp die, and when I accidently left out the powder one time during load development, the bullets never moved out of the crimp even though the primers went off, backed out, and tied up my revolver (A 7.5" Redhawk that I use for load development).
This is the minimum load I'm willing to use as it leaves the last 1/2" of the case blackened on the outside, indicating there's not enough pressure to seal the case against the cylinder wall. It runs about 800 fps out of my 7.5" Bisleys, not sure what it runs out of my Marlin 1894, but it feeds without any problem in my rifle. I got the idea for this load from Hodgdon's webpage on Cowboy loads for the 44 Mag - if 5.0 grains worked for a lead 200 gr 44 bullet I figured it would work even better for a 215 41 bullet.
