Samari46: Yes I did get the powder numbers jumbled. I'm old... lol. I settled on the AAC 5744 as suggested by El Gato. Just want to make certain of my pressures with that powder with the intent to use 170-220 grain cast boolits in .323 diameter. Thoughts? I ask a lot of questions in areas I am not that familiar with. That's how I learn. Been reloading for just over 40 years now but never messed with cast boolits until I got my Martini-Henry and it is still a work in progress on the loads. I enjoy loading the blackpowder and cast combination. This is new territory so I'm SOAKING UP INFO LIKE A SPONGE! Thanks for the help Sir!
