What’s the purpose of a ported barrel? Wouldn’t that reduce velocity?
It reduces muzzle climb at the expense of reduced velocity. Neither effect is particularly significant in a shotgun.
What I would really like to know is why the shotgun has a visible choke only in the top barrel. That makes no sense for skeet. Neither does the fact that he’s got no vest and no extra ammunition.
This is (was) a staged photo op, no question in my mind.
Have seen this discussed on various other posts of our skeeter in chief today.
The gun has ports on both sides of the barrel to help minimize the kick up as the shot passes by. EG - improves accuracy.
Note that you were given a "tip". Gasses are only leaving one side of the gun. Maybe a optical due to light or timing of the camera's shutter. Just sayin'
