Gen-fics with Tony Stark being a competent shooter

[marlowe78.livejournal.com]

Hey, it's me again. Thanks for the help last time, but I would like some more input from you all :-)

So, my request is for Tony being a good shot with guns, because... he'd be able to know how to use a gun, right? (though I'm not saying he has to be competent at shooting PEOPLE - that's different)

I've already been combing through the tags in this community, but well, see... I'd like them to be either gen, Pepper/Tony or if all else fails any pairing that is NOT Tony/Steve or Tony/Loki (Where does that one come from, btw? Not judging, just asking) and I thought it would be easier if I get a bit more specific.

Is there anything like this? I've read one or two already, but rec away, I'll just re-read.
And while I'm already asking difficult things: are there communities for fic-posting that aren't AO3, because I'm already combing through there and I don't wanna miss anything :-)

Thank you all!
