296/H110 is my go to powder for loading 410 shotshells. L'il Gun is great for it too but does burn hot and shotgun is where you shoot a fir amount of ammo in a short time. I use LG in the Hornet. Can't really overload it. I have a couple containers of TB I can load some mouse fart loads for my wife in her 45 SA Ruger...or I can use said 231 or anything else. I have partial cans of all sorts of powders...alot discontinued but good powdersesp the DCd Duponts 5066, PB ,7625,4756,800X,4227 and the hard to find Hercules/Alliant RL7,10,11, 21,Bullseye, RD,GD, Unique, Herco and 2400...Even some Blue Dot....and a lot of newer easier to find suspects. If'n I can't find a powder to use I would say I lost my mind
