Deer hunting caliber rules in Texas
What Texas allows you to shoot a deer with, in plain English, taken from the state's own regulation and quoted below so you can check our reading against it.
A plain-English summary, last reviewed September 2026. Hunting law changes every year and varies by zone, season and public versus private land, and this page is not legal advice. Before you hunt, confirm the current rule with Texas Parks and Wildlife Department.
Centerfire rifles are legal and the state sets no caliber floor that rules out a .223.
The rule as Texas writes it
Except where specifically restricted elsewhere in the chapter, it is lawful to hunt game animals with any legal firearm, including a muzzleloader, and no minimum centerfire caliber is set. It is unlawful to use rimfire ammunition to hunt deer, antelope or desert bighorn sheep. An air gun used for deer must be a pre-charged pneumatic firing a projectile of at least .30 caliber and a bullet of at least 150 grains at a minimum muzzle velocity of 800 feet per second, or any combination producing at least 215 foot-pounds of muzzle energy.
Is a .223 legal for deer in Texas?
Yes. Texas sets no caliber minimum for deer, so the cartridge is legal here; what the state's rule, quoted at the top of this page, asks for is a centerfire cartridge - rimfire ammunition is unlawful for deer, alongside the implement rules for the season you are hunting. Many hunters still choose more cartridge for deer, and with a .223 the bullet choice carries the whole load.
What is the minimum caliber for deer in Texas?
Texas sets no minimum caliber for deer. Its rule asks for a centerfire cartridge - rimfire ammunition is unlawful for deer, so the choice of cartridge is yours, and so is the responsibility that comes with a small one. The state's full wording is quoted at the top of this page.
What an open rule means for your rifle
This state trusts the hunter to bring enough cartridge. There is no caliber floor written into the deer rules, so the legal question is usually settled by two other things: the cartridge must be centerfire, and the bullet must be one that expands. Rimfire rounds and full metal jacket bullets are the usual exclusions.
Legal is not the same as adequate. A .223 will kill a deer with a well-constructed bullet placed in the lungs at modest range, and it will wound one with a thin varmint bullet through the shoulder. If you hunt with a small cartridge, the bullet is the decision, not the caliber stamped on the barrel.
Read the rules for the season you are hunting. Many open states still run separate archery and muzzleloader seasons with their own implement rules, and a rifle that is fine in the general firearm season is not legal in those windows.
Caliber is the smallest part of a clean kill. Work out what your cartridge carries at the range you hunt with the cartridge and energy guide or the cartridge comparison tool, then put the shot where it counts.
