What is the best caliber for hog hunting?
Outdoor Life's own recent hog-caliber testing settles on a working principle rather than one magic cartridge: hogs need a bullet that penetrates deep and holds together, not one built for speed and fragmentation. Their picks span a wide range of cartridges built around that same idea:
| Cartridge | Example load | Muzzle velocity | Muzzle energy | Best for |
|---|---|---|---|---|
| .270 Winchester | 130gr Power-Point | 3,060 fps | 2,702 ft-lb | Budget, widely available factory ammo |
| .308 Winchester | 150gr SST Superformance | 3,000 fps | 2,997 ft-lb | AR-platform rifles, all-around use |
| .30-06 Springfield | 150gr SST Superformance | 3,080 fps | 3,159 ft-lb | Outdoor Life's overall pick with a 175gr bonded bullet |
| 6.5 Creedmoor | 143gr ELD-X Precision Hunter | 2,700 fps | 2,315 ft-lb | Mild recoil, dual-purpose deer/hog rifle |
Manufacturer-published figures, 24-inch test barrel, muzzle only. Outdoor Life's specific top pick uses a 175gr Federal Terminal Ascent in .30-06, a heavier bonded-core bullet than the 150gr load shown here; see Sources for the article.
Why hogs need more bullet than deer of the same weight
A mature boar grows a layer of thick, dense cartilage — commonly called a "shield" — over its front shoulders that can run up to roughly 2 inches thick. Outdoor Life explicitly excludes lighter cartridges like .223 Remington from its hog recommendations for exactly this reason: a fast, fragile varmint bullet can fail to penetrate that shield, where a slower, tougher, bonded or controlled-expansion bullet punches through into the vitals instead. This is the single biggest difference between choosing a deer caliber and choosing a hog caliber — the energy numbers on paper can look similar, but bullet construction is what actually decides whether the shot works.
What bullet construction actually matters?
Bonded-core and controlled-expansion hunting bullets — Federal's Terminal Ascent and Fusion, Winchester's AccuBond, and comparable bonded designs from other makers — are built to expand without fully separating from their jacket, which keeps them driving forward through dense muscle and cartilage instead of stopping short. A cheap varmint bullet, or even a standard cup-and-core deer bullet pushed to high velocity, is more likely to fragment on the shield itself. If you already have a favorite deer load in one of the cartridges above, check that it uses a hog-appropriate bullet before assuming it transfers straight over — see best deer hunting calibers for how deer-focused loads in these same cartridges are usually built.
Where do you aim on a hog with a rifle?
Behind the ear, angled toward the far eye, is the standard instant kill shot, and it goes around the shield entirely. A true broadside shot high on the shoulder also works with an adequately tough bullet. What to avoid is a steep quartering-toward or straight-on shot on a mature boar — exactly the angle where the cartilage shield is most likely to turn or slow a marginal hit. This is the identical shot-placement logic used for airgun hog hunting, just at a completely different energy scale; see hog hunting with an airgun for the big-bore PCP version of the same rule.
Is 6.5 Creedmoor good for hog hunting?
Yes, with the caveat that it's a mild-recoil, do-it-all choice rather than the hardest-hitting option. Outdoor Life calls it a "great hunting cartridge" for hogs specifically, and its 2,315 ft-lb at the muzzle is plenty for a clean kill with the right bullet. It's the pick for a hunter who already runs 6.5 Creedmoor for deer and doesn't want a second rifle, more than it is the top recommendation for someone buying a rifle specifically to hunt big, tough boars at close range.
Hunting hogs with an airgun instead of a firearm
Firearms and airguns solve the hog problem on completely different energy scales, so don't try to translate the numbers above directly onto a PCP rifle. Big bore air rifles need 150-250 FPE for smaller hogs and 400-700+ FPE for mature boars — see hog hunting with an airgun: big bore setup and shot placement for the full caliber and energy breakdown, which runs from .30 caliber up through .50 caliber big bores.

Good fit
- .270 Win, .308 Win, .30-06, or 6.5 Creedmoor loaded with a bonded or controlled-expansion bullet
- Hunters willing to wait for a true broadside or head-angle shot instead of forcing a marginal one
- Anyone already owning one of these calibers for deer who wants to add hogs without buying a new rifle
Look elsewhere
- .223 Remington or other light varmint cartridges — Outdoor Life specifically excludes them
- Any cartridge paired with a fast-fragmenting varmint bullet instead of a bonded or controlled-expansion design
- A steep quartering-toward or head-on shot on a mature boar, regardless of caliber
Verdict
Any standard deer-class cartridge from .270 Winchester up — loaded with a bonded or controlled-expansion bullet, not a varmint round — kills hogs cleanly. Outdoor Life's overall pick is .30-06 Springfield with a 175gr Federal Terminal Ascent, but .308 Win, 6.5 Creedmoor, and similar cartridges all work if you already own one. What actually fails hunters on hogs isn't the caliber, it's a light varmint bullet meeting a mature boar's cartilage shield at the wrong angle.
FAQ
What is the best caliber for hog hunting?
There's no single best cartridge, but .270 Winchester, .308 Winchester, .30-06 Springfield, and 6.5 Creedmoor all reliably kill hogs with a tough, controlled-expansion bullet. Outdoor Life's own hog-caliber roundup picks .30-06 with a 175gr Federal Terminal Ascent as its best all-purpose choice, citing deep penetration and reliable expansion at both close and long range.
Why is .223 Remington not recommended for hogs?
A mature boar develops a cartilage "shield" up to about 2 inches thick over its front shoulder, and a light, fast-fragmenting bullet built for varmints doesn't reliably punch through it. Outdoor Life explicitly excludes .223 Remington from its hog-caliber recommendations for this reason — hogs need a bullet built to penetrate deep, not one built to fragment on impact.
What bullet construction works best on hogs?
Bonded-core or controlled-expansion hunting bullets, not varmint bullets. Outdoor Life's top hog picks include Federal's Terminal Ascent (bonded core), Winchester's AccuBond, and Federal's Fusion — all designed to hold together and penetrate a shoulder shield rather than expand explosively on the surface.
Where do you aim on a hog with a rifle?
Behind the ear for an instant head shot, or a true broadside shot through the shoulder into the vitals. A steep quartering-toward or straight-on shot risks deflecting off a mature boar's cartilage shield, the same reason airgun hog hunters wait for a clean broadside or head angle rather than forcing a marginal shot — see hog hunting with an airgun for the same principle at lower-power scale.
Is 6.5 Creedmoor good for hog hunting?
Yes, for hunters who want mild recoil and already own one for deer. Hornady's 143gr ELD-X load makes 2,315 ft-lb at the muzzle, and Outdoor Life calls it a "great hunting cartridge" for hogs specifically because of its accuracy and proven bullet performance, though a heavier, harder-hitting option gives more margin on a large boar at close range.
What caliber airgun does it take to hunt a hog?
A big bore PCP, generally .30 caliber and up, making 150-250 FPE for smaller hogs and 400-700+ FPE for mature boars — a completely different energy scale than a firearm, since air rifles can't match a centerfire cartridge's velocity. James hunted an invasive hog with a .30 caliber FX Impact M4 shooting ACE FRAG slugs; see hog hunting with an airgun for the full big-bore breakdown.
Do you need a magnum cartridge for hogs?
No. Outdoor Life's picks run from .270 Winchester up through 6.8 Western, and a standard deer-class cartridge with the right bullet handles the great majority of hogs. A true magnum only starts to matter for consistently taking large, mature boars at longer range.
