Secret Service agent hit by buckshot from the gun of man charged in correspondents' dinner attack, prosecutor says

[melm00se]

12. 00 Buckshot

is 9 x 0.33" pellets.

The shot pattern (for cylinder choke) expands radially at ~2" per yard traveled.

There is no way to determine with certainty that a shotgun pellet came from a specific shotgun as there are no lands and groves in a shotgun barrel to leave an identifying mark on the pellet (not that is an absolute link to any firearm...this ain't TV).


The best that they can claim and claim to show

1. The alleged shooter was armed with a shotgun.
2. The shotgun was loaded with [insert specific round here].
3. No other officer was armed with a shotgun.
4. There was one spent cartridge ejected or still in the chamber.

One question that I have:

There is a video showing the alleged gunman entering a doorway with no long gun visible. A folding shotgun by Mossberg, when folded, is ~30" in length which is not easily concealable, so where did it come from?
