Oh yeah, speaking of Fauna; one time I joined a stream, sent a single chat 2 minutes after joining, and she read it and laughed. Take that, non-chatter. (All my other stories of being read are about IRyS, obviously)
Sounds like she has a pretty common misconception about rifles vs. handguns: shooting a rifle is way easier than shooting a handgun (and especially a magnum, if she were to try that). Especially when, for first time shooters, you could swap out the bolt and magazine in an AR and turn it into a 22lr. Heavy gun+small round+more points of contact=super easy.
If I were taking someone out shooting I'd go in that order: 22lr AR -> swap AR to normal 556 -> handgun -> magnum handgun. And if you want to toss in a shotgun, either before or after handgun. Probably before.
A week or so ago some guy was spazzing out on 4ch saying he 'dug too deep' and found stuff about them interacting before. But, being 4chan, he obviously provided no proof, evidence, hints, details, or anything at all.
