Should a 45LC S&W revolver chamber 454 Cassull?

My 625 S&W 45lc will fully chamber the longer 454 Cassull rounds. I would have thought this wouldn't be possible for safety reasons. Is this normal?
I'm not stupid enough to try and fire them in this revolver, but am kinda surprised that they fit.
 
They should absolutely not chamber. I had heard something about this awhile ago, it's not 'normal' but a manufacturing defect I presume.

You might want to drop Smith & Wesson message and ask them why they made the cylinder so long . or maybe not . just in case something goes wrong with that revolver in the future. heck if you dropped the hammer on one of those rounds you'd more than likely be picking shrapnel out of your head. not good .
 
Even hot loaded .45 Colt intended for stronger modern designs do not run anywhere near the pressure of .454 (30k psi vs. 65k psi). Seems like the OP isn't gonna ruin his day by pulling the trigger but you know someone, somewhere is dumb enough to do it. Very irresponsible of SW to cut the chambers long enough to fit the Casull cartridge...
 
Lengthwise, the .454 Casul case is only .096 longer than the 45 Colt. (1.381 vs 1.285)
Interestingly enough, the Casul case at the web is .476 vs .480 of the 45 Colt, so it should fit. And does in your 625.

Whether it is a factory cylinder mistake or not, I don't know, but it fits. Will the .454 factory round turn in the closed cylinder?
 
There’s a great reloading YouTuber named fortunecookie45LC or something like that that did a bunch of videos on this topic. He had the same issue.
