Comparing Ballistics: 308 Winchester vs. 30-06 Springfield

When it comes to ballistics, the 30-06 Springfield and 308 Winchester share many similarities but also showcase their own distinct strengths:

• Muzzle Velocity: The 30-06 typically has a slight edge at moving heavier bullets more efficiently, but the 308 shows higher velocities due to greater pressure and light bullets.
• Trajectory: The 30-06 maintains a flatter trajectory over extended ranges, giving it a marginal advantage for precision shooting at longer distances.
• Performance in the field: Both cartridges perform nearly identically within 300 yards, making them equally suitable for shots on medium-sized game hunting in those distances

Recoil Comparison: Which Cartridge Offers a Smoother Shooting Experience?

Recoil is a critical factor for many shooters, especially those sensitive to the impact or who plan to shoot multiple rounds during a session.

• The 308 Winchester generates about 14% less recoil than the 30-06 Springfield when firing similar bullet weights at relative velocities.
• For example, an 8-lb rifle firing a 180-grain bullet at 2,610 fps in 308 produces roughly 16 ft-lbs of recoil energy, compared to 18.5 ft-lbs for the 30-06 at 2,700 fps.

This reduced recoil makes the 308 more comfortable for extended shooting and a preferred choice for newer hunters or shooters prioritizing follow-up shot speed and accuracy.

Best Uses for Hunting: Is 308 or 30-06 Better for Your Needs?

30-06 Springfield

The 30-06 excels when hunting larger game or in scenarios requiring heavy bullets for deeper penetration and complete pass throughs. It’s a popular choice for:

• Deer, elk, moose, and bear hunting.
• Dangerous game requiring heavier bullets (e.g., 200+ grains). These heavier bullets provide greater momentum which translates to greater penetration on North America’s largest game.
• Open plains or long-range shooting where the 30-06’s energy and trajectory shine. Combing the 30-06 with a bipod and a quality optic enables you to make distant shots with confidence.

308 Winchester

The 308’s versatility and reduced recoil make it a favorite for:

• Whitetail deer, antelope, hogs, coyotes and other medium-sized game hunters.
• Hunting where shorter, lighter rifles are advantageous. Ideal for hunting out of a tree saddle, a climber, a lock on tree stand.
• Varmint hunting, thanks to lightweight bullet options (~150 grains and below). Even though there is no such thing as overkill, varmints do not require much more than 100 grains.

Availability and Cost of 308 Winchester and 30-06 Springfield Ammo

Both cartridges are widely available, but the 308 Winchester tends to have a slight edge in cost and variety:

• Factory Ammo: Both calibers are readily available at competitive prices, though 308 often offers more budget-friendly options. There is no shortage of either between Remington’s 14 product lines.
• Reloading Supplies: Components for both are easy to source, but 308 brass is more abundant due to its widespread use in military and sporting scenarios. You can also use fired brass, so you are not always purchasing brass. Just be sure to thoroughly inspect for abnormalities.

Overall, both cartridges remain affordable and accessible, ensuring you'll always find either in time for your next hunt or range session whether that’s in the store or online.

Long-Range Shooting: How Do 308 and 30-06 Compare for Distance and Accuracy?

For long range enthusiasts, the 30-06 Springfield offers superior energy retention and less bullet drop over distances of 300+ yards. However, the 308 Winchester holds its own with excellent accuracy and wind resistance, thanks to its short-action design.

• 30-06 Advantages:
  • Flatter trajectory at long ranges.
  • Greater terminal energy for long-distance shots.
• 308 Advantages:
  • Easier to shoot consistently due to reduced recoil.
  • Popular in precision rifle competitions for its inherent accuracy.

For long-range applications, your choice may depend on rifle setup, bullet selection, and shooting discipline.

Final Thoughts: Which Cartridge Should You Choose?

Whether you opt for the 308 Winchester or 30-06 Springfield, you’re choosing a proven performer with decades of history and reliability. Both can handle a wide range of hunting and shooting scenarios. Before you make your decision, be sure to shoot the cartridge for yourself. Even further, try to match what firearm you are looking at purchasing.

• Choose the 308 Winchester for reduced recoil, versatile applications, and short-action rifle compatibility. The 308 is the perfect cartridge for the whitetail hunter, and a personal favorite of mine. My go to cartridge is the Core-Lokt tipped 180 gr.
• Opt for the “Ought 6” when you need maximum power, heavy bullet capability, and superior long-range performance. This cartridge has won two world wars and is owned by millions of gun supporting Americans. That is the truest testament to the success of the 30-caliber powerhouse. It will not steer you wrong.
