If you're planning on using that particular taper crimp die for 45 schofield and 45 Colt for pistols, you would be making a mistake. A). That die is actually intended for 45 Mag Auto Pistol Cases. Yes, the 45 Mag is about the same size as a 45 Colt case without the rim. It head spaces on the case mouth. The taper crimp is normally applied to bullets without a crimp groove. An auto pistol does not have the same "in-line" recoil as a tube magazine rifle.
Most CAS loadings are reduced and have some issues with ignition. Bullets with a crimp groove and a good roll crimp are recommended. Also, when used in a rifle, with a taper crimp your liable to encounter "Turtles." With properly designed bullets, the roll crimp should crimp right to the bottom of the crimp groove. This will hold true for revolvers as well as rifles. Should you happen to load with BP, the crimp is really critical.
In summation. Skip the Taper Crimp die. Should you want a really good roll crimp die, I would highly recommend the Redding 45 Profile Crimp Die for everything except 45 ACP. Obviously, for 45 ACP, a Taper crimp is appropriate.
