Typically, AR-15 rifles are loaded with .223 Remington cartridges, which are housed in bullets with a diameter of 5.7 millimetres [sic].

Okay, if I’m running a ‘fact checking’ site, like Snopes, then I best make sure the stuff posted on my site is correct.
It’s obvious Snopes was lazy or ignorant or both concerning the above quote from their site and I think it says something about their credibility.
Background: Snopes is fact checking a poster that shows a black circle about three inches in diameter with the text:
“This is the size of a hole made by an AR-15. Tell me again why you need that?”
Snopes’ verdict on the poster is not ‘True’ and not ‘False’ but their rating is ‘Mixture’ which their definition is:
This rating indicates that a claim has significant elements of both truth and falsity to it such that it could not fairly be described by any other rating.
P.S. I don't want to argue the merits of the 'Mixture' rating as Snopes jumps through many hoops and even disregards an expert opinion they themselves solicited. I just want the very first quote, at the top of the post, to show that they do not do the work they should to get their facts 'checked'.
