I've heard it told that people often misjudge a 2.5" chamber because they load a standard 2.75" shell in the chamber and the action closes on it. However, as we know, a standard 2.75" shell is actually closer to 2.5" when unfired and therefore should chamber without issue in a 2.5".
I've often wondered if you can therefore make a rough estimation of a standard 2.75" chamber by seeing if the action will close on a 3" shell? I don't plan on using this technique if my life depended on it, but I've just been curious if this would technically work?
