See what I mean? Book just repeats the myth in my mind, though as you say I guess a tweak of the myth. But you're Exactly right. Said by who? According to what? It's just a claim, and in my opinion contradicted by every single public document and contemporary marketing or Colt related material I could find from the time period. Same thing with military, of course that would be contradicted by any/every military related service rifle training program or materials ever.

Still on wikipedia though. Because writing bullshit without any source is fine as long as it's in print, I guess?

Well at some point, Wikipedia became less about writing an encyclopedia and more about creating and enforcing a set of rules that (hopefully) would eventually lead to a "high-quality" encyclopedia. So if you want to fix Wikipedia, you can't just edit Wikipedia (it'll be reverted), you have to justify your edits according to Wikipedia's core policies (Verifiability, no original research, and neutral point of view). Probably you could also explain why those policies are wrong and need to be changed, but that would be a longer discussion and wouldn't necessarily take place in the context of a specific article. Just guessing, but probably in this case the issue is a lack of secondary/tertiary sources - there is material from that period, but nobody has analyzed it and come to a conclusion on this sub-subject besides this author. So because (per verifiability) secondary trumps primary, the secondary is what is in the article. I think all you could do is get those claims removed, because synthesizing a different conclusion than the book would be original research.

Seems to me it'd be a lot more high quality if you could simply have points about truth or things being opinions, or speculation, or rumors, or myth, stuff like that. Or simply noting there's disagreement or things about truth. Maybe you can but I ain't about to spend my whole year learning a bureaucratic jargon just to "sneak in" what should be effortless to put there. Get my frustration?
