The short answer is no, but I have a bunch of old (handload) boxes with a succession of labels, and one or two labels at the bottom may have a recipe for Al-7. I used it in the mid-sixties for hot 20 ga. loads (1 oz. @ 1200 fps) but by about 1970 had changed over to the more easily obtainable IMR 4756. That will give you an idea of its comparable burn rate. Anyway, a quick check of those old boxes all had 4756 labels. I'll dig more tonight. I recall that Al-7 looked nearly like coal, slightly coarser than powdered.
