Aloha,
Reason I asked and based on what I have found online from various other forums,
This is what I found on the local county/town level:
Sec. 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 of firearms on lots that are 10 acres or smaller and are located in the unincorporated area of the county in a subdivision.
This is the state law I found:
Sec. 229.002. REGULATION OF DISCHARGE OF WEAPON. A municipality may not apply a regulation relating to the discharge of firearms 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 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 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 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
10 acres for a shotgun, bow, or air rifle and 50 acres for any handgun or rifle
As I have mentioned before, After the Wife retires, we hope to move to Texas Hill Country.
The Wife presently works at the Permitting Dept of local government, she wants to make sure we don't have problems with our range.
Having Our(My) Private shooting range is the last on My Bucket List.
Not being a bother to neighbors is important to us.
. Well, I do buy targets and ammo
