Thank you. Currently using Seirra and Hornady data, CCI 300 primers, Federal brass, and H-110. I have started low and am working up. 2 differnt weapons are being used. A Ruger Blackhawk, 45/8" barrel and a M657 Classic Hunter II with 6.5" barrel. Yes I know each weapon will handle differntly. I was just checking for more recomendations as this is a copper skined SWC and I have been told I do'nt need to worry about leading. Have loaded rounds at both 1200 and 1250 and the 1250 was just a tad ruff on the hands out of the Ruger.
