Yes I know it will defineatly be louder, right now I shoot a Rem 7400 carbine, I like the shorter barrel, makes it better in the thick brush and blanket bogs of the adks. I will probably never shoot over 60 yards, and will be using a Leupold Vari X III 2.5-8. I guess the reason I want to cut it down is the same reason the Benoits cut theirs down.
