Choosing the Best Caliber for Exotic Hunting in Texas

What caliber to bring for Texas exotics, from a 70-lb blackbuck to an 1,800-lb Cape buffalo: cartridge and bullet by weight class, and the Texas rules.

One rifle rarely suits both a 60-lb springbok and an 1,800-lb buffalo, and a Hill Country ranch can put both on one list. Choose the rifle for the largest, toughest animal you plan to hunt, then choose the bullet. Get those two right and the rest is practice.

Texas leaves the choice to you. On private property, Texas Parks & Wildlife sets no required means and methods of take for exotic animals, so there is no state minimum caliber for an axis, an oryx or a buffalo. What follows is hunting judgment, not law. You still need a Texas hunting license, and native whitetail follow TPWD's legal means and methods, which bar rimfire ammunition of any caliber.

Small antelope, gazelles and hog deer (60 to 180 lb)

Springbok (60 to 100 lb), blackbuck (70 to 120), hog deer (70 to 110), dama gazelle (90 to 165), impala (100 to 160) and blesbok (120 to 180) are light and thin-skinned. Any good deer cartridge will do. The gun writer Chuck Hawks put blackbuck in the same size class as pronghorn and said the same calibers suit either. Pick a controlled-expansion hunting bullet, not a varmint bullet that comes apart on the shoulder.

The hard part is the target, not the cartridge. Small animals have small vitals and rarely stand still. A steady rest matters more here than anywhere else on the ranch.

Axis, fallow, red stag and the other deer (90 to 700 lb)

For axis deer (150 to 250 lb), Chuck Hawks put it simply: any good North American deer cartridge is a good axis cartridge, and a magnum is not required. The same goes for fallow (130 to 220 lb), sika (90 to 200 lb) and whitetail. On deer this size, a standard expanding soft point does the work.

Step up in bullet construction for red stag (350 to 500 lb), Père David's deer (300 to 450 lb) and sambar (400 to 700 lb). They can weigh twice what an axis does, with shoulders to match. A good deer rifle can still serve; the change that matters is a tougher bullet, heavy for its caliber. Nyala and Nile lechwe (180 to 280 lb) fall in between.

The tough ones: aoudad, oryx, wildebeest, nilgai and sable (220 to 600 lb)

Some animals are hard to put down for their size. Heavy bone, thick shoulders and tough hide can stop a bullet built for whitetail before it reaches the vitals.

• Oryx. For the scimitar-horned oryx (300 to 450 lb) and gemsbok (400 to 550 lb), a flat-shooting rifle in the .270 to .300 class with a quality bonded bullet is a common choice. The same rifle suits addax (200 to 300 lb) and the big-bodied waterbuck (400 to 575 lb).
• Nilgai. The nilgai (400 to 600 lb) has a thick hide and heavy shoulders. Most hunters choose a .30-caliber magnum or similar with a premium bonded bullet.
• Wildebeest. Hunters call the blue wildebeest (400 to 600 lb) the poor man's buffalo: heavy in front, built like a tank and hard to anchor. Bring what you would bring for oryx.
• Sable. A sable (450 to 600 lb) is big, muscular and will fight with its horns. Treat a .270 as the floor; a .30-06 or similar is better.
• Aoudad. The aoudad (220 to 300 lb) is the lightest of the group, but wild sheep are tougher than their size suggests. A .270 to .30-06 class rifle with a tough, well-constructed bullet suits them, and the same rifle suits urial and Nubian ibex.

Kudu, eland, elk and bison (450 to 2,000 lb)

A bull greater kudu weighs 450 to 600 lb; Craig Boddington, the longtime African hunting writer, puts an average bull at about the size of a young bull elk. Common kudu choices run from the .270 Winchester to the .300 Winchester Magnum, and Boddington has called the .30-06 an ideal plains game rifle. Use a tough, heavy-for-caliber bullet.

Above that, the weight climbs fast. Elk run 600 to 900 lb, and the classic elk cartridges, the 7mm Remington Magnum, .300 Winchester Magnum and .338 Winchester Magnum, all serve here. An eland can reach 2,000 lb. Boddington calls the eland a special case, more than twice the size of any other antelope. He likes a .375 for them but suggests one of the fast .33s as the more versatile choice.

American bison (1,000 to 2,000 lb), yak (700 to 1,300 lb) and Watusi (900 to 1,600 lb) are cattle-sized, with heavy bone. They call for something heavier than your deer rifle and a premium bullet. Ask us before you choose.

Cape buffalo

A Cape buffalo bull weighs 1,000 to 1,800 lb and is dangerous game. Buffalo call for heavy dangerous-game calibers like the .375 H&H or larger, with solid or premium bonded bullets. Texas sets no minimum here either; this is the standard hunters hold themselves to. Talk with us before your hunt.

The bullet matters more than the cartridge

On tough animals, how a bullet is built matters more than how fast it goes. A standard cup-and-core soft point opens fast, which is what you want on a thin-skinned axis or blackbuck. Driven into the shoulder of an oryx or a nilgai, the same bullet can come apart before it reaches the heart and lungs.

• Bonded: the lead core is fused to the jacket, so the bullet expands but holds its weight and keeps going.
• Monolithic: solid copper or copper alloy, with no core to shed. It opens and penetrates deep.
• Solid: built not to expand, for the deepest penetration on dangerous game such as buffalo.

Choose a bullet on the heavy side for its caliber, zero with the exact load you will hunt with, and if you bring one rifle for a mixed bag, load it for the toughest animal on your list. For where to put it, read our notes on shot placement on African plains game.

Bringing your rifle

Confirm your zero before you hunt and again after any flight or long drive; a scope that moved in transit can cost you the animal. Practice from field positions, not just the bench.

If you fly, the TSA rules for traveling with firearms are plain: the rifle goes unloaded in a locked, hard-sided case, in checked baggage only, declared at the airline ticket counter. Ammunition is checked too, never carried on, packed in a box made for it, and your airline may limit how much you bring.

Every hunt at Black Eagle is fully guided; your guide helps you read the animal and pick the moment. The rifle is your call. Tell us your rifle, cartridge and bullet when you reserve your hunt, and we'll tell you whether it suits the animals on your list. Daily rates and trophy fees are on our pricing page.
