RCBS .452 - 185 SWC BB, What's your favorite load for a 45 ACP?
Just cast and coated a bunch of these, looking for a good starting place IE what powder and charge worked best for you.
I'll use your favorite loads as a median charge [IF it fits in the parameter of load manuals safe ranges.] and work up and down from there.
I don't have ZIP ( the recommended best load) or N320
Otherwise, I'll have to start at the top and work my way through the powders in .2 grain increments then narrowing it down by the loads nearest the best groups I get.
