Right, not a levergun but didn't know where to post that was better. Anyway, I have lyman design round nose that casts around 200gr. 2 lube grooves no crimp kinda like the 42798. Barrel looks good enough for a cast bullet. Suspect the action isn't much stronger than thw Winchester '73. Would like the load that gives me max velocity and 11,000-13,000 cup. I'm aware of the titegroup load and have lost interest in trail boss. Any suggestions would be welcome. I think Colt revolver bores were .427+or-. Anyone have some idea before I start slugging?
