I'm curious, how old is the Blue Dot you have? Is it Alliant Blue Dot or Hercules Blue Dot? If it's from some time ago, it may have a different burn rate than the currently manufactured stuff. Hercules had some kind of plant explosion in the late 80's early 90's, and after that, the formulation changed.

I double checked the label. you're right vince, it was Hercules Blue Dot. Is the burn rate much different with the new formula?
Thanks Ray for the lead-on. I'm still considering whether to load 1 1/4 oz rounds - specially when you said the muzzle flash is quite a show. lino
