Another mossberg question.

Jack,
Shotgun porting doesn't increase the sound, yea right, only if your the poor slob standing next too it.
Have a buddy who's duck gun broke and he brought his sporting clays gun. (ported) I had the misfortune to be next to him in the blind. Not only is it loud but in the early morning low light the flames across your face is just a little unnerving. Hell, it scared the bejesus out of me. I actually used my ear plugs that day, and when I'm trying to use a call that makes it difficult.
We also have a couple who shoot Mossberg 500 turkey guns at the trap range. The combination of porting and short barrel length really really is noticable to all but the shooter. BOOM
