I've tried this though don't remember the outcome, but I would guess a .451" jacketed or cast bullet would fall through some, maybe many .45 ACP/ Auto Rim chamber throats and all .45 Colt chamber throats. I use .452" cast bullets because they are more accurate than .451" cast in .45 ACP/ Auto Rim and a minimum of .454" in .45 Colt.

Jacketed bullet are pretty forgiving of bullet diameter and I suspect .451" jacketed should work well in revolver chamber throats like they do in semi-autos, but I seldom shoot jacketed bullets in any handgun and can't confirm this.
