This did not happen to me but instead, a very ggod friend. Back in my BuckSkinner days, we all had the Mountain-Man trappings. A friend of mine had it all and did not stop with the teepee. He had a horse who was also all decked out. He even trained the horse to hold, while he shot his M/L while mounted. He got so good that he rode in local, small town parades.
In one such parade, he could not take the usual side-shot, so he pointed the muzzle out between the horses ears. .... Yep !!!
Next thing he remembers, was laying on the ground, looking up at the horse and folks asking if he was all right ....
Be Safe !!!
