I agree, just buy the 2.5 ammo or have it bored out to take 2 3/4. Some folks will say shoot the 2 3/4 ammo anyway, but it isn't a great thing if the forcing cone is too close to the chamber. Will raise pressures.
I've got a 16 I have to buy 2.5 ammo for. If I planned on shooting it a WHOLE lot, I'd reload 2.5.
BTW, there's a good read on doublegunshop about lengthing chambers. I wouldn't do it as it reduces the walls perhaps too much.
