By the way if you have a problem trying to reloading lots of weapons after a big fight then you can actually drag ammo over your weapon to reload it instantly.
My favorite thing to do is headshot a zombie with the crossbow, loot the zombie and drag the bolt over my crossbow to reload it.
Pimp. That is a profession in the game, I saw someone upload it on Miiverse.
Also I am way way up there on the leaderbords, ask my anything.
