I am always suprised when someone reminds me that Pres. Obama smokes cigarettes or shows me a picture like the one below, wherein I realize, again, that he is left-handed. The White House released this 2012 picture to confirm that the president shoots skeet. I do a bit of that myself (with an Ithaca 20-guage double-barrel, modified over improved).
Maybe because I am a very inexperienced shooter, I don’t know what I’m seeing, but in the picture below there appear to be two smoke plumes coming from the president’s gun. The one coming from the muzzle is, obviously, the smoke that emerges right after a shot. But what’s the second plume, apparently at right angles to the first, that looks as though it is coming from some kind of vent in the side of the barrel? There’s certainly no opening or other potential source of such a plume on my Ithaca. If anyone reading this knows what it is, please let me know in the comments.
