I tried binding fire to mousewheel and it seemed to be firing pretty slowly (slower than I can click). I hear people say they use a free scrolling mouse wheel. Is that a specific type of mouse or just a setting somewhere?

some mouses can press a button on their mouse and the scroll wheel doesnt brake. touch it and it spins forever on same speed (well it slows downs, because physiks, but you get the concept)

Logitech g502 is a great mouse with free scroll

Ok, I don't think mine has that feature. Thanks for the suggestion seanpr
