This is pages old by now but Thor recently stood upto a hail of assault rifle gunshots and didn't blink. It was the issue that took place in Africa where he found the warriors three in mortal guise.
That scan with ares getting shot shows him taking damage then firing a weapon with an accuracy that was superhuman. I'm sure he's that good with just about any weapon he's practiced with. That's gotta be as good or in the ballpark of any of the world's best. I mean he's the God Of War.
