With both my 280 lyman cast, and the 330gr LBT I cast, the loads listed in the Lyman manual, are pretty stout out of my DW. Just a couple tenths under max, works well with W296 and H4227. Not sure what rifle your loading for, but you might want to just stick with the loads they worked out for handguns. They also have several listings for a T/C in pistol lenght barrels. Seriously, unless your going out after griz, and even then I don't think you'ld be too much under gunned, that cartridge will take anything on this continent. gypsyman
