many, many pre 1926 made guns have chambers opened to 2 3/4"...

guess what, the bores are not bulging in front of the chambers and they are certainly not blowing up...

listen to your gunsmith...and follow his safety guide lines...re barrel wall thickness and recommended loads for your particular gun...
