The following have worked with a 215 LSWC in my 6" model 29:
11.3 grains HS6 (Fed LR primers), v. easy shooting
4.8-5 grains Red Dot (WIN LR primers), v. easy shooting
8 grains of Silhouette (WIN LR primers), light and easy, no flash
7.45 grains 700x (Fed LR primers), easy handling but flattened primers
I see no reason to beat myself up with full powered loads in a .44mag, so I tend to stick with light loads. I can shoot these all day long, no problems.
