Greetings all, I'm a new poster to this website....excellant forum. I have been loading .45 Colt for CAS Using Hodgdon CLAYS and am very satisified however....I would like to try Trailboss due to its bulk preventing a double charge in a progressive press. I am still using my old Dillon 450 (20 years + )with a LEE Pro Autodisk powder measure....I know I should upgrade the machine to a 550 but I am so used to using it as is. My question is, will the larger holes in the LEE disk drop the needed 5.5 to 6.5 grains of Traiboss? Does anybody use a LEE disk measure with this powder? With the Dillon measure it is recommended to use the rifle measure with Trailboss as the pistol measure doesn't have enough volume. Does anyone know the VMD of this powder? Thanks in advance, shoot safe, Bisley
