I would shoot any factory load without reservation. As far as handloads I have been shooting the Keith bullet as well as the Thompson gas checked bullet with either 7.5 g or 8 g of Unique . I have a second model that is a few years older than yours . This is not a weak load but is not stout enough to cause any issues with older guns . I would probably avoid the Keith load using 2400 and the 429421 , it is right at magnum class and won't blow anything up but will speed up wear and tear on hard to replace parts in older guns. I shoot that one in my Flattop Ruger.
My 429421 mold is the original style mold and throws 250 grain bullets. The Thompson bullet 429244 is a 255 grains and my mold is actually 431244 .
