I just checked again the old handbook.
The shotshell loading recipes are on page 130.
Charges for 10, 12, 16, 20, 24, 28, 32 and "410 Gauge or 36 calibre" (sic).
For the column it only says: "Powders for loading Skeet, Trap and Light Hunting Loads" and, besides Hercules Red Dot, there are DuPont MX, B-P Super-M and Acapnia.
There are no presure or velocity listed.
