After the previous discussion, I checked out Promo in some detail and found information that coincides with the information you just provided. Plus it's supposed to be less expensive than Red Dot.
So.............
I'd like to get some Promo and try it just for the sake of doing so and see if there's any discernible difference between it, Red Dot, factory loads, and anything else I've used.
FWIW, whenever I try different powders and loads, whatever, it always seems to me that they just go BANG! like everything else, the leads on the bird don't change, and there's not a whole lot of difference.
However, when I read the reloading forums, the pros always are pointing out the nuances between loadings.
Guess I need Sensitivity Training.
