In my question I did say plated in reference to the bullets but jacketed would be correct. I saw a loading chart that said 5.0-5.1 grains of powder for a 260 grain bullet but don't remember what brand the powder was. They are .451 diameter. I have looked at several online loading charts and don't see anything for a 250 grain bullet under 45 ACP but everything seems to be in the 5 grain range on powder amount in the closest weights I can find data on. The powder I have is Winchester 231.
