I didn't get a response from Ranier via email so was wondering if anyone has loaded these for a .45acp. I have their HP 230 gr. plated bullets and want to use Unique powder, but don't know if I should use Lead cast or FMJ load data. Alliant's website has for the 230 FMC to use 6.0gr; 230JHP 6.4gr; and 230 Lead 5.0 gr. I used 5.6gr it goes bang and cuts nice holes. I don't have a chronograph. Should I be using closer to the lead cast load data or the FMJ data? Should I go lower than 5.0? http://www.rainierballistics.com/mainframe.htm http://www.alliantpowder.com/reloaders/RecipeList.aspx?gauge=>ypeid=1&title=Pistols and Revolvers http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=158548
