I just always shoot around them. STart oput with a 22 while they are eating. And they are always around other gun broke horses. Rarely does it take more than an hour or two to gun brea ka horse. When people come to the CMS exhibitions, the horses have been hearing the gun fire as they get closer and closer to the arena. Then yopu park in the trailer area and tack them up, and there is gunfire the whole time. Then you ride up to the arena and sit on him while you watch the vent. Then, when it is time to try yours spout, you get in the arena with a CMS on horseback. You lope around the rail with the shooter loping beside you. He will shoot his gun on the off side while you lope around the arena. Then, he wil hand you one to shoot off of yours when you lope around. If you use the horse ear plugs, and are always careful to shoot off to the side and never over hois head, where he can get powder burned, most horses are good to shoot off of that first day. Lot easier to gun break a horse than a dog, IMO.
