Man, you're such a bro. It's funny, I'm been a gun-nut and a military otaku for so long that it doesn't even occur to me that so much of this stuff isn't common knowledge. YOU'RE DOING A GOOD THING HERE MAN KEEP IT UP.

I'm just gonna add here,

Anti-tank rifles are usually shown as capable sniper rifles in fiction. For the most part, they suck at this role but where frequently relegated to this action only because they sucked a lot harder as anti-tank rifles.
