For muzzle rise, NOT to be confused with recoil reduction, porting MIGT have some minor value. I see NO value in porting the top barrel, a la Browning, as there is no third shot to acquire.

I have the utmost respect for Zippy and Jim, but I really don't place much value in porting - even for targets. If you THINK it works, then it works, whether true or not. The few studies and high-speed photography I have seen do not, IMO, show a discernible adjustment in muzzle rise.

It seems funny that P guns, Zippy's favorite, do not come with porting, yet they are THE choices for some of the fastest shotgun games known - bunker and pigeons.............

Again, if YOU think it works, go for it. If I find a gun I want that has it, I will not NOT buy it because of the porting, but I will never spend extra $$$$ to have it done..
