Yes, many are 2.5". All of my current guns are 2.75", I should have said so. Some people cut 2.75" shells even if they will be shot in 2.75" chamber, when they roll crimp.

I should have added, that I don't know when 2.75" became common in America, but I have English and other guns from turn of the century that have 2.75" original chambers.
