Know of any good hunting spots in central Texas?

I live in Round Rock TX and the most I've hunted here are local parks. Considering my area is pretty new, I'm itching to hit some older towns/locations within driving distance. Preferably under 3 hours of driving. My main focus is coin shooting, but relics are great as well. Any suggestions are appreciated! Thanks!
