Hop on the 50 East going towards sand mountain. It's about 15-20 minutes away. What you wanna do is look for signs for the Grimes point turn off. You can google "Grimes Point" and just go where the GPS takes you. you'll turn left onto a dirt road. Drive about a mile then pick a spot. You'll see plenty. Plus there is an old nuke test site called "project Shoal" You can google that too its about another 20 minutes down the 50. Plus the navy bombing range.
Edit... It's not an actual range but thats where we go to shoot legally.
