I have acquired a Winchester 1885 High Wall which was originally chambered in 32-40. It was rebored to 40-82 Sillouhette (Crossno) and I have C&H dies for it. Does anyone have load data for this caliber using Chey-Cast 400 gr Snover (.409) 1:20 Alloy - BP Lube bullets? I have brass that came with the gun. Someone said I could load black powder or modern powder and I need to know for sure. Thanks.
