Well AFAIK jacketed or lead use the same data. These were 250gr jacketed I also use 250gr lead sometimes. I know those Rugers can take double the loads I would never go there. If it can't be fixed then there will be a lot of .45 loading stuff for sale.
If you look atanuals for both types of projectile, like the Hogdon or lee manuals, you would see the data is very different.
