Any SAAMI compliant load will be safe in both actions. Stick to published load data for standard .45 Colt loads and you will be fine.Hi all looking for a good all-around reload for 45 Long Colt to be used in Uberti 45 and you Uberti 1860 Henry will welcome any suggestions or something that will perform good and keep the pressures were they need to be for that old action.
And pressures which was exactly what I was talking about.Just stick with the data for standard 45 LC actions, not Ruger / Contender, and you'll be in the safe zone. I've used HS6 for this before with really good performance.
As for being SAAMI compliant loads, SAAMI doesn't approve load data, they standardize cartridge and chamber specifications.
