How to deal with really loose/big betting player?

I think you're playing him absolutely correctly. You dont ever want to bluff someone like that cuz they counter aggression with more aggression. Be a calling station, nothing is going to irritate him more than having every one of his big bets cold called. Check calling in hands he's in will allow you to begin to pick up on his bluffing habbits so that later when he makes the same play you can come over the top. This is just how I handle bulleys, do as you wish.
