Advantages of a stratified (triplex) load in a .45acp: .460 Rowland ballistics in an unsupported barrel, using regular acp cases, low muzzle flash, and with no bullet set back. No risk of a double charge, since a person is using a compressed load. People are spending lots of money on conversion kits, when they are unnecessary. My pressure testing equipment shows a consistent pressure curve most of the way down the barrel. The fast powder next to the magnum primer, gets the powder charge moving away from the base of the case, which keeps the base from taking the brunt of the pressure. The fast powder on top of the charge helps burn up powder and gasses, that would otherwise be muzzle flash. Case life and primer pocket life is increased. Also is a good survival method. I have used IMR 4895 in the .45 acp, and got good results. There is no one powder made that can do all of this. Sorry to disappoint you, but have never blown up a gun.
