.41 is very easy to load. It is a straight case and works well in the dies. I have been loading for it since the 80's. I have a variety of cases and they all work well.

My favorite load is 7.0 of Unique with a cast 210-220 grain cast swc. It is mild and accurate. I use mostly WW primers as that is what my LGS carried. I have also used Federal, Remington and CCI.
