I have a Mossberg 835 with the porting. I don't notice that it is any louder than my other guns that aren't ported. I do notice that I am slightly faster to get back on target with the ported barrel. I believe that was the intent of the porting all along, and it seems to me that it works. It is my favorite duck gun for that reason.
You can't fix stupid....however ignorance can be cured through education!
