An all-original unmolested early (or later) Colt M1917 cylinder will not properly accept .45Colt ammo.

Here's a pic of my all-original early style Colt cylinder that will not fully accept .45Colt ammo. (It's the same revolver/cylinder as in my previous pic showing the unclipped .45acp ammo going in flush with the rear cylinder face.) This is another reason I try to correct folks when they say early Colt cylinders were originally bored straight through as this is an incorrect statement. If they were simply bored straight through then .45Colt ammo would go all the way into the chambers.
