Wes, I'll agree, to a point
Blue Dot would not be a good choice at .38 Special pressure. I shot a few cans of AL-8 in hot .38 Specials with similar results. Accurate enough, but too much unburned powder would get under the extractor.
However, Blue Dot has always been a high performance 124 gr. jacketed 9mm powder. I shot it for years. There can be fairly substantial variations in different lots though. Best to work out of kegs.
Years ago, my friend called Hercules and got them to run pressure on a really nice clean burning 44-40 load with a 200gr. lead slug and Blue Dot with heavy crimps that my buddy and I had been shooting for a while. Checked out OK. They have since quit listing it I believe.
But I have noticed Alliant - or whoever owns them now - have eased off on listed uses for both Blue Dot and one of my favorites, Herco.
