I have an ithaca M51. I sent the barrel to Briley and had it choked and fiber optics put on it. It is a great skeet gun. I use it as a backup duck gun or a gun to lend. Since I bought my SBE 2 I have not had to use it. I think it would work well with 2 3/4 hevi shot. It shoots so well I won't get rid of it.
