I'm surprisingly good with the railgun. I'd say I have a 70% hit rate with it or so, maybe an extra 10% if you count splash hits (then I just switch to my secondary).
I really suck with the human sniper rifle. I'm okay with the scattershot, but not very. I'm terrible with the shotgun because I don't camp with it. I'm envious of people who can properly use that damn sticky launcher.
