As long as the gun has adequate barrel thickness, which with the proofs it has it probably does, extend the forcing cones and then go ahead and shoot 2-3/4" shells through it. That solution has always worked great for me. With modern thin walled plastic cases, extending the forcing cones is a good idea for better patterns even if you stick with 2-1/2" shells.
