Just PMd you back and saw this.
Yeah, there's no 1k range here for obvious reasons. Noone would go.
The area I PM'd you is a great spot to find/set up a range and has almost unlimited options. I stay out of the AZ side because I shoot at night as well as seems AZ has decided to start sending their BLM cops out on the AZ Strip area telling you that you now need a permit to camp/ride out there. Not sure what happened but all of a sudden most of that area is 'state trust land' and now they want money; which is a total joke as there's nothing special about it and its surrounded by Utah BLM land. Kind of like charging for a random spot on the beach, surrounded by more beach.
