I just purchased a Beretta Stampede, 7 1/2 inch barrel, in a .45 Colt. I also have and load a Ruger Blackhawk in a .45 Colt, but wouldn't attempt to use the same loads in the Beretta. What loads can I safely use, and what "strength" category would it fall into? Ken Waters "Pet Loads" shows 3 categories and most reloading manuals separate the "old" Colts and the Ruger/Contender pistols. The pressure difference is a max of 18,000 CUP on the former category and 30,000 CUP on the latter with no data in-between. Any help would be appreciated,including favorite accuracy loads, target loads, and hunting loads. Thanks - Riley
