as to lengthening chambers to 2 3/4... its about barrel wall thickness in front of chambers...generally speaking, if after lengthening chambers, you still have .090 in front of chambers, you should be ok for safe shooting with light loads...might as well have forcing cones done as well...

always seek professional help...

and be aware that any alteration to a gun may reduce its resale value...
