Has your dog been to obedience school? If not, I would start there. No collar or device can take the place of training and should not.
For a well-trained dog with super high prey drive and a tendancy to bolt, I would recommend a prong and not a choke chain. As you are seeing, choke chains don't stop the pulling, they just do what their name implies - "choke".
A prong collar needs to be properly fitted - this is very important or you could injure the dog. You never correct or jerk a dog wearing a prong collar, as the dog corrects himself while wearing it.
But first your dog needs to learn, understand and obey commands. Obedience school teaches YOU how to train your dog. I highly recommend it. It did wonders for me and my dog.
