The big problem is the background. He must have been standing in front of the “low house” aiming parallel to the road, or path, which runs along the woods there. At least this checks with his left handedness ( note “Swoosh” checks OK, ) but it is an awkward arrangement.
In other photos, shooters can be seen standing near the “high house” on the other side, aiming generally outward, but of course those photos prominently feature the house itself. It is curious that it is such a tight shot.
And say, how come I don’t see anybody saying what kind of gun that is. I guess the upward puff is due to a muzzle brake designed to compensate for “kick”. It’s hard to find another example image of this, though. And what’s with the brass muzzle fitting?
Good observation, could be or..Photo taken on camp David helicopter pad road.
They were to lazy to walk 1/4 mile to camp David skeet range for the pr photo taken for election that was never used.
Camp David skeet range has wooden fence around it.
It’s a Browning Citori Lighting Sporting Clays, and it is “ported” which is supposed to reduce muzzle jump (never could tell on any of my ported guns). The fitting is an extended choke tube, which allows for quick changing of chokes on the sporting course for differing shots. The bottom either has a flush mounted choke tube, or no tube (not a good idea).
