Two shooters at least.
But there is reason to doubt Mike Adams. If he's telling truth now, he's like the boy who cried "wolf!" due to past (carefully presented) wild claims, that he does excel at selling as legitimate. It's made himself a lot of money. The man is a dedicated salesman. There is no room for doubt about that.
In the video presentation ---
Did anyone else notice that this Mike Adams/Health Ranger guy said he obtained the recordings from internet videos (note the multiple) yet showed us just the one image purported to objective sound analysis?
In his theorizing he may be on to something regarding triangulation, yet he did not show a processed version of an alleged recording that actually showed (through this sound analysis technique) that there was a second shooter allegedly "overlapping" on the same tape (even though fairly early in the video, he said that he would show that - he never did).
In light of the sound recording that he included in the video demonstration, presence of a second shooter, along with the rest of the 250 yard hypothesis is coming out of thin air. At the least he's not showing the source for the second set of calculations upon which the 250 yard circle is based.
There was no indication from which particular youtube video he obtained (and allegedly used) the sound recording he claims he's expert regarding canceling out "background noise". These things are significant.
Can anyone show the man has sound engineering background? Has he claimed that among his many and varied claims he has made for himself (regarding himself) in the past? In his video, of course he represented himself merely as an experienced long-range shooter -- but then segued right into portraying himself as expert in canceling out background "noise".

SunkenCiv, and good 'ol Ernest_at_the_Beach may appreciate this next link;
in part because, in comments section is link to
that was posted by PZ Meyers. Does that name "PZ Meyers" ring any bells with you guys?
And this last that I'll include (that admittedly I don't know what to make of regarding the alleged-to-be actual quotes, that sounds a lot like satire itself, while presenting itself as admission from Adams that he engages in satire -- and keeps getting away with it) from a gal who bills herself as Scibabe;
