.308 vs .30-06

The short version

The .308 Winchester and .30-06 Springfield fire the same .308" diameter bullets and deliver nearly identical performance in the most common bullet weights (150–168gr). The .30-06 has a longer case that holds more powder, giving it a 50–100 fps velocity advantage. That advantage becomes more meaningful with heavy bullets (180–220gr) where the extra case capacity translates to real ballistic gains.

Quick takeaway: If you hunt deer-class game inside 400 yards, the two cartridges are functionally interchangeable. Choose based on what rifle you want. If you hunt elk, moose, or large bears — or reload heavy bullets — .30-06 has a meaningful edge with 180–220gr loads. If you shoot precision/tactical, .308 is the standard.

Ballistic comparison — 150gr

The most popular hunting weight for both cartridges. Data from 24" barrels.

At 150gr, the .30-06 runs 90 fps faster — roughly a 3% velocity advantage. In practice, this translates to about 1.3" less drop at 400 yards and 6% more energy at 300 yards. Meaningful on paper, but no animal will know the difference.

Ballistic comparison — 168gr match

For precision shooting and long-range target work.

With match bullets, the .30-06 gains roughly 70 fps. The ballistic difference is small enough that the .308's advantages — shorter action, more available match ammo, shorter bolt throw — make it the dominant precision cartridge despite the slight velocity deficit.

Where .30-06 pulls ahead — heavy bullets

This is the only area where .30-06 has a clear, meaningful advantage.

At 180gr, the .30-06 delivers 10% more energy. At 220gr, the gap widens to 20%. The .308's shorter case simply can't hold enough slow-burning powder to push heavy bullets efficiently. This is why .30-06 remains popular with elk and moose hunters who prefer deep-penetrating 180–220gr loads.

Bullet drop comparison — 165gr

A middle-ground weight popular for both calibers. Zeroed at 200 yards.

At 500 yards, the .30-06 drops 2.5" less. Not enough to matter for hunting — both require the same holdover techniques.

Recoil comparison

Recoil depends on rifle weight, bullet weight, and powder charge. Estimated from an 8-pound rifle:

The .30-06 generates 10–15% more recoil due to the heavier powder charge. Both cartridges are tolerable for most shooters, but the .308's lighter recoil is noticeable over a long range session or a multiday hunt. This is one reason .308 is more popular for high-volume precision shooting.

Rifle and action considerations

The short-action advantage is real for bolt-action rifles: shorter bolt throw means faster cycling. It also means a slightly lighter, stiffer action. For semi-auto shooters, .308 has far more modern platform options — the AR-10, M1A/M14, FN FAL, and SCAR 17 are all .308. Modern semi-auto .30-06 rifles are essentially limited to the M1 Garand.

Ammo cost and availability

.308 is generally 10–20% cheaper than .30-06 across all categories. Military surplus 7.62 NATO FMJ is the cheapest way to shoot either caliber at volume. .30-06 surplus exists but is increasingly collectible rather than shootable.

Both calibers are available at every sporting goods retailer, big box store, and online vendor in the country. Neither will ever be hard to find.

Barrel life

.308 barrels last notably longer because the shorter case burns less powder per shot. For high-volume precision shooters, this translates to meaningful cost savings over the life of the rifle. For hunters who fire 20–40 rounds per year, barrel life is irrelevant.

So which should you buy?

Choose .308 Winchester if:

• You want the widest selection of affordable ammo
• You shoot precision or competition (it's the standard)
• You want a semi-auto option (AR-10, SCAR 17, M1A)
• You hunt deer-class game inside 400 yards
• You value lighter recoil and shorter bolt throw

Choose .30-06 Springfield if:

• You hunt elk, moose, or large bears with 180–220gr bullets
• You already own a .30-06 and it shoots well (there's no reason to switch)
• You reload and want to push heavy bullets to their potential
• You want one rifle for everything from pronghorn to grizzly
• You appreciate the heritage (the U.S. military's primary rifle cartridge from 1906–1954)

The honest answer: For 90% of American hunters, both cartridges will kill the same animals at the same distances with the same effectiveness. Pick the rifle you like, not the cartridge.
