As it is cool here today, spliting wood was the order of the day so I did not get the chance to do any cylinder measurements. But they are calling for rain and that means back to the reloading bench. As you mentioned Loyd, properly labeling is a must, but if for some reason we are not there to guiide the choice, I want to insure no one grabs the wrong combo. Most non reloaders would think that .45 Colt loads would fit a same marked revolver or rifle. Even though ninety percent of my bullets are cast, changing OAL seems like an extra measure of safety ad should be easy to do. If the cylinder won't turn, they can't get hurt. You have a good point about the .454 and using only that brass, that would leave just the model 92.
