I've done a little tinkering but haven't been happy with the results. Problem is this is a low pressure cartridge and loads are based around 85-100 gr. lead with a couple loads for an XTP (a waster in my opinion).

If you REALLY want to do this, use 85 XTP Max loads as your baseline to begin with. Use FAST powders as the 71 gr. will be light for caliber AND you are using a smaller capacity case.

I've done my work with a Ruger SSM so I am not worried if I go over book pressure...YMMV.
