I use RedDot in my plinking handgun cartridges (9mm, .40, .357, .44mag and .45acp) but it has become impossible to find. I'm down to 2lbs of RedDot and have enough empty brass to use most of it. I ordered 8lbs of Alliant Promo to use in place of my RedDot. According to Alliant, Promo has the same burning speed but is slightly denser so powder measures will had to be adjusted to throw the same powder weight. Alliant says that I can use my loading tables for RedDot with the Promo. I'm just curious of results that others have gotten using Promo. I hated to buy 8 lbs but the hazmat fee makes trying a 1lb container too expensive. Since both my sons are shooters a pound of powder doesn't last too long.
