For moderate pressure loads, I have had success with Trailboss, using slightly heavier cast bullets than you intended to use.

Instead of listing my load, I will refer you to the manufacturer’s recommended technique for determining a safe charge.

This old cartridge is one of the very few I use Trailer Boss for, and I don’t use anything near the maximum load as suggested by Hodgdon.

Mine's a tale that can't be told, my freedom I hold dear.
