Actually, state law does address it in at least two places, quoted below. Basically, these restrict the way in which municipalities (§229.002) and counties (§235.022) may regulate the discharge of weapons within their boundaries. It appears to me that if you have any amount over 10 acres and are not within the jurisdiction of a municipality you may discharge weapons, except that you can't allow the projectile to cross a property line unless you own both pieces of property (this bit about property lines is from §62.0121, which I have not quoted).
-------------------------
§ 229.002. REGULATION OF DISCHARGE[0] OF WEAPON. A
municipality may not apply a regulation relating to the discharge[0]
of firearms[0] or other weapons in the extraterritorial jurisdiction
of the municipality or in an area annexed by the municipality after
September 1, 1981, if the firearm[0] or other weapon is:
(1) a shotgun, air rifle or pistol, BB gun, or bow and
arrow discharged:
(A) on a tract of land of 10 acres[0] or more and
more than 150 feet from a residence or occupied building located on
another property; and
(B) in a manner not reasonably expected to cause
a projectile to cross the boundary of the tract; or
(2) a center fire or rim fire rifle or pistol of any
caliber discharged:
(A) on a tract of land of 50 acres[0] or more and
more than 300 feet from a residence or occupied building located on
another property; and
(B) in a manner not reasonably expected to cause
a projectile to cross the boundary of the tract.
------------------------------------------------
§ 235.022. AUTHORITY TO REGULATE. To promote the public
safety, the commissioners court of a county by order may prohibit or
otherwise regulate the discharge[0] of firearms[0] on lots that are 10
acres[0] or smaller and are located in the unincorporated area of the
county in a subdivision.
