I don’t think there’s load data for Pyrodex on the spreadsheet. This apparently it’s from a 1983 listing right from Pyrodex. I found it interesting because there was a 2 ounce load at 6900 psi with 100 grains of Pyrodex. Not much more than my low pressure. I’m running with black powder right now with one and 5/8 ounce. Like a good heavy payload, low pressure load if somebody wants to turkey hunt. I see it’s 3 1/2 inch but I would assume loading it at 2 7/8” “it fits in a hull” is going to be the same pressure. If not, there’s a nice low pressure load for the one in 58 ounce 2 7/8”. I’m running 100 grains of FG with the one in 58 ounce load and I’m guessing it’s around the same pressure is 80 grains of Pyrodex. I have a metal can with a pound of CTG powder. I’ll have to try a few test loads. I’m sure gluing in an OS card in an all brass hull will give me plenty of room for 2oz of shot and keep me at lower pressures. RST advertises their ”Damascus safe” ammo at 6,500 psi. I’m sure 90 and 95 grains with 2oz will be right at the same pressure area since a 100 grains is 6,900. IMO it’s nice to find a “ heavy payload” with lighter pressures for turkey hunting.
