Late Teen or man (I'm not sure of age when story started) kicked back to mid 1800s in area of Phoenix, or possibly Tucson Arizona. He becomes bounty hunter since he knew much of the area from extensive hunting in the area when he was younger. He knew of caves in the area where outlaws might hide out. I believe main weapon was a shotgun, at least initially. Catches many outlaws and woos young lady.
I thought it was from aubie56, but reviewed all of his I can find as well as both topic and custom searches, but no luck.
Does this sound familiar to anyone?
