I hope I'm misinterpreting your statement. All else being equal powder volume doesn't change how many rounds you get per pound.

I think he's referring to a powder like Bullseye where the charge weights are fairly light so you get more charges per pound of powder, that will generally be slightly cheaper to reload. As an example in Speer #14 loading a 165 gr jacketed bullet, the starting charge for Bullseye is 5.3 gr while for AA #7 is 9.6 gr. Breaking that down, using that charge you could get 1320 rounds per pound with Bullseye, and only 729 per pound using AA #7, or 1.9 cents per round for Bullseye and 3.4 cents per round for AA #7. (Using $25 a pound for the estimate.)

I used to think like that, but over the years I've come to prefer something in the middle, one problem with Bullseye is that in many cartridges its difficult to detect a double charge by looking at the charge in the case.

I have tried 3 different powders in 40 S&W, WW231 is an old favorite from when I shot competition with mild 38 special loads, Unique is a good middle of the road powder, works well in 40, and Blue Dot. I would characterize my experience with Blue Dot as a failure, it is a very poor choice in that caliber. One day I went to shoot at a range where there was a white painted table in front of the shooter, after 25 or 30 rounds there was so much unburned powder on the table I could have written my name on it. Clearly visible in the unburned powder where the little blue dots that identify Blue Dot powder. IMHO Blue Dot powder is a very poor choice for 40 S&W.
