I had a Redhawk rechambered from .44 Magnum to 45 Colt minimum specefications by Clements. I haven't seen a great improvement in accuracy but the expected improvement in case life was nice. A bit more "free" velocity with the same loads too. I have only one complaint, my "standard" Clement's conversion brass now has to be watched as it given special status and not fired in my other .45 Colts. Please don't tell my how many brass I could have thrown away for the price of the conversion. I want a .45 Colt Super Redhawk so this discussion of the 454 Casull chambered gun using 45 Colt brass is a great "project" starting place.
