LGS who is high on powder/primers has an 8# jug of Promo for $140. I understand it is interchangeable with red dot. Same burn rate, a little more dense.
What calibers does it excel at and how does it flow? How's the price? Any powder that is less than $20 a pound is a deal right now to me.
How would it do in my favorites 38, 357, 41, 45acp and 45 colt?
