Just found this site, kinda by accident. Anyone have some reloading info for the 40-65 WCF with cast bullets? GC or plain base will work. I have started working up loads with a 260 gr round nose flat tip bullet using IMR 4198 for my Sharps replica gun. I started with a load of 23 gr. and have arrived at a final load of 31 grains. Extraction is sticky above 31 grains. Also wondering about just how fast I can push a plain base bullet and if a wad would help. Since I found the starting load in my Cartridge Conversions book, I have looked for more loads with a slower powder but to no avail. Any suggestions or help would be seriouslt appreciated.
