I have been researching for old 2 7/8” 10 gauge data and have read on a few forums that Lyman use to have load data in their older load data books. I have the new Lyman book and to be honest I haven’t looked through it to see if there is any. I’m sure there is no shogun data in it. If someone has an old Lyman reloading book can they post some pics of the data? I am using RST 2 7/8” hulls. I just have 7 so far. I bought 3 boxes of 10 and will eventually have all 30 to load when I blow through them. I have green dot, red dot, and 700x. I also have FG, FFG, and FFG. Federal 209 primers. For wads I have sp10, BPD 10, and multi metal. I have ballistic products x10x gas seals and overshot cards. I also have two different Alcan shot wads. One approx a god 1/2” plus thick wad and the other looks to be a 1/4” thick I’m guessing. I bought them from a member here and won’t have them for a good week or so. I also ordered #6 nickel plated shot from ballistic products and have sone #5 lead shot coming as well. From all my research it seams like 1 1/4 oz is about the heaviest payload around 1150 FPS for Damascus barrels. I would have liked to go 1 1/2 to 1 5/8 oz but I want to keep my loads at safe pressures. I have been reloading centerfire for over 20 years but never reloaded for shotgun. I want to make sure I do it safely. From what I see powder, shot card, cushion, lead, and with another shot card or crimp. I am trying to duplicate an RST load. From what I’ve read they use a cardboard shot card over the powder (no shot cushion wad) and a Remington sp10 wad, then crimped? Anyone one familiar with their load? What power and charge is used? I would assume a shot card is needed to compress the powder in every load and then more are inserted and or a cushion to basically take up space in the casing to get a proper crimp? I’ll be using my lee loader and want to fold the original crimp back over.
