The 45 ACP case is .898" long, the 454 Casull case is 1.383" long. If you fire a 45 ACP in a 454 Casull cylinder the unsupported bullet will have nearly 1/2" of freebore that is .026" larger than the bullet to slop around in prior to being forced through the throat. Imagine trying to throw a 3" ball through a 3" hole from 3 inches away. This is not a recipe for accuracy, IMO.
