I was previously using 2400 for all my 44 magnum loads but I had one can of the "old" Unique powder as well as a bottle of the new Unique. I popped open the old stuff and loaded some with 10 grs behind a 240 SWC and some more with 11.7 Grs same bullet. I also loaded some with 2400 at 18, 19, and 20 grs and went out today to shoot some groups. I found that while the 2400 shot great in my OM Super and shot well in my 5.5" Redhawk that all the Unique loads shot better than all the 2400 loads. I didn't shoot the Blackhawk today but have shot lots of the 2400 loads out of it before. I assumed that a charge that fills the case would show better consistancy and accuracy but the Unique loads worked better.
