I agree - get a second opinion from someone who can personally examine the gun and accurately measure the chamber length.
That being said, I have an 1898 DH built on a 2-frame with 2 9/16" chambers that has easily digested many hundreds of 2 3/4" AA trap loads. These days I shoot RST 2 1/2" shells simply because they're easier on the shoulder.
I can't comment of what kind of shells have been used with this gun prior to my ownership of it.
