.45-70 vs .30-06: Which Is Better for Big Game?

The .45-70 Government and .30-06 Springfield have both earned legendary status among big-game hunters, but they got there in very different ways.

The .45-70 is a big-bore cartridge built around a large, heavy bullet. It has long been associated with lever-action rifles, thick timber, bear country, and hunting where shots are likely to be relatively close.

The .30-06 takes a different approach. Its smaller, more aerodynamic bullets leave the muzzle considerably faster, giving the cartridge a much flatter trajectory and making it far more comfortable when hunting across open country or at varying distances.

Both can take big game. Both have been doing it for generations.

But if you’re trying to decide which one belongs in your hunting rifle, the answer isn’t simply a matter of which cartridge produces more energy.

The .45-70 makes the most sense when your hunting is close, heavy, and carried out in thick country. The .30-06 is the better choice when you want one rifle that can handle a wider range of game, terrain, and distances.

That’s the real difference.

One important caveat is that .45-70 performance varies considerably between loads and rifles. Traditional ammunition is not the same as modern hunting ammunition designed for stronger actions. A .45-70 label alone doesn’t tell you exactly how a particular load will perform.

That is worth remembering throughout this comparison.

The .45-70 Is About the Bullet

The .45-70’s appeal becomes easier to understand when you stop comparing it with modern high-velocity cartridges.

It isn’t trying to win a trajectory contest.

The cartridge uses a .458-inch bullet, and hunting loads commonly put a lot of lead downrange. Depending on the ammunition, .45-70 bullets can weigh 300 grains, 325 grains, 350 grains, 405 grains, or substantially more.

That creates a very different kind of hunting cartridge.

Instead of relying primarily on high velocity, the .45-70 combines a large frontal diameter with considerable bullet weight. Modern hunting bullets have also made the cartridge substantially more capable than its original black-powder-era reputation might suggest.

That combination is particularly appealing when hunting in country where the terrain naturally keeps shots short.

Think thick timber. Heavy brush. Black bear country. Close-range elk hunting.

In those situations, the .45-70’s limitations at longer distances may barely matter.

The .30-06 Is About Versatility

The .30-06 has a much broader personality.

It can be loaded with relatively light bullets for deer or with heavier projectiles when the target becomes larger. It has been used for practically every major category of North American big game and remains one of the most widely supported hunting cartridges in terms of rifles and factory ammunition.

Its .308-inch bullet is also considerably more aerodynamic than the traditional .45-70 projectiles.

That matters as soon as the distance starts opening up.

A .30-06 hunter can move from timber to fields to mountain country without the cartridge becoming dramatically less useful. The trajectory remains manageable, ammunition is plentiful, and there is a tremendous range of hunting bullets available.

That’s why the .30-06 remains so difficult to replace.

It isn’t necessarily the most specialized cartridge for any single hunting situation.

It’s simply good at an enormous number of them.

Why the .45-70 Still Makes Sense

It would be easy to look at the .45-70’s trajectory and conclude that it has been surpassed.

That misses the point.

Hunters don’t choose cartridges based solely on maximum range.

A short lever-action rifle chambered in .45-70 can be extremely practical in dense cover. The rifle is often compact and easy to handle, while the cartridge provides the heavy-bullet performance that makes the combination attractive for close-range big game.

Modern ammunition has also pushed the .45-70 well beyond its original military role.

For example, Hornady’s 325-grain FTX load was designed to improve the trajectory of the .45-70 while maintaining the cartridge’s big-bore character. Other modern loads use bullets designed specifically for hunting deer, elk, bear, and other large game.

The important point is that today’s .45-70 is not the same proposition as the cartridge’s original 19th-century loading.

It’s a modern hunting cartridge built around an old design philosophy.

Where the .45-70 Starts to Give Up Ground

The tradeoff becomes obvious when the range increases.

Heavy .45-70 bullets can hit hard, but they generally don’t retain velocity as efficiently as the smaller, more aerodynamic bullets used by the .30-06.

That produces more drop and greater sensitivity to wind as distance increases.

A modern .45-70 load can certainly extend the cartridge’s useful range compared with traditional ammunition, but that doesn’t turn it into a flat-shooting western hunting cartridge.

If you’re glassing across a broad valley and aren’t sure whether the next opportunity will be 100 yards or considerably farther, the .30-06 is simply the easier cartridge to work with.

That’s not a criticism of the .45-70.

It’s a consequence of what the cartridge was designed to do.

Where the .30-06 Pulls Ahead

The .30-06’s greatest advantage is what happens when the hunt doesn’t go according to a neat plan.

Maybe you’re hunting whitetails in timber in the morning and sitting over an open field in the afternoon.

Maybe you’re chasing elk in the mountains and could encounter an animal in thick timber or across an open basin.

Maybe you’re traveling for a hunt and want one rifle and one cartridge that can handle several species.

The .30-06 is exceptionally good at those situations.

Its trajectory gives the hunter more flexibility, while its enormous selection of bullets means there are plenty of ways to tailor ammunition to the animal and hunting conditions.

This is why the .30-06 is still such a strong “one rifle” cartridge.

.45-70 vs .30-06 for Deer

For deer, either cartridge is an excellent choice.

The better one depends largely on the terrain.

If you’re hunting whitetails in dense eastern woods where most shots are relatively close, the .45-70 is a very natural fit. Its big bullet and compact lever-action rifles are particularly well suited to that style of hunting.

If you’re hunting mule deer in western country, or whitetails where fields and longer sightlines are common, the .30-06 has a clear practical advantage.

The .30-06 also gives you more room to grow as a hunter. If your deer rifle eventually becomes your elk rifle, you don’t have to replace it simply because your hunting plans changed.

For a dedicated close-range deer rifle, I’d have no hesitation choosing a .45-70.

For a general-purpose deer rifle, I’d take the .30-06.

.45-70 vs .30-06 for Elk

Elk are where both cartridges become particularly interesting.

The .45-70 has a legitimate place in elk country, especially where terrain keeps shots relatively close. A heavy .45-70 bullet is well suited to the kind of short- and moderate-range hunting often encountered in timber and heavy cover.

The .30-06, however, gives you considerably more flexibility.

Elk aren’t always standing at 75 yards in the timber. A hunt can just as easily put you on the edge of a meadow, across a burn, or looking into an open basin.

When that happens, the .30-06’s flatter trajectory becomes a meaningful advantage.

So if I knew I would be hunting elk exclusively in thick country, the .45-70 would be a perfectly sensible choice.

If I wanted one elk rifle for a mixture of terrain, I’d choose the .30-06.

What About Bear Hunting?

The .45-70 has a particularly strong case for bear hunting in thick cover.

A compact lever-action rifle and a heavy .45-caliber bullet make a natural combination when the terrain limits visibility and shooting distances.

The .30-06 is equally legitimate, particularly when hunting black bear in more open country. Its greater reach can become useful when a bear is spotted at a distance or when the hunt involves mixed terrain.

So again, the terrain matters as much as the animal.

Thick cover favors the .45-70. Open or mixed country favors the .30-06.

What About Moose?

Both cartridges have enough capability for moose when paired with appropriate hunting ammunition and used within sensible distances.

The .45-70 has obvious appeal in close-range moose hunting. Its heavy bullets fit the cartridge’s traditional role extremely well.

The .30-06 has the advantage if the hunt may involve longer sightlines.

That’s the recurring theme here: the .45-70 becomes increasingly attractive as the distance decreases, while the .30-06 becomes increasingly attractive as the terrain opens up.

Which Has More Recoil?

There isn’t a single recoil number that tells the whole story.

A .45-70 can be loaded fairly mildly, or it can be loaded with very heavy bullets and substantial velocity. The rifle’s weight also makes a major difference.

In general, though, a typical heavy .45-70 hunting load will produce more noticeable recoil than a conventional .30-06 hunting load.

The .30-06 is not a featherweight cartridge. Anyone who has spent an afternoon shooting full-power hunting ammunition knows it can kick.

But the .45-70’s heavy bullets can make recoil particularly noticeable.

That’s worth considering if you’re choosing a rifle you’ll practice with regularly.

The best cartridge isn’t much use if you dislike shooting it.

Which Has the Flatter Trajectory?

The .30-06 wins this one easily.

Its smaller, faster, more aerodynamic bullets give it a much flatter trajectory than traditional .45-70 loads.

Modern .45-70 ammunition has improved the situation significantly, but it hasn’t changed the fundamental character of the cartridge.

That’s why the .45-70 works so well when the hunter knows the shots will be relatively close.

The .30-06 gives you considerably more forgiveness when distance increases.

And that forgiveness matters.

You don’t have to be an expert long-range shooter to appreciate a cartridge that doesn’t require as much elevation correction as range increases.

Which Has the Better Bullet Selection?

This depends on what you want from the bullet.

The .45-70 has the advantage if your priority is large, heavy projectiles.

The .30-06 wins if you’re looking for the broadest overall selection.

The .30-caliber bullet market is enormous. Hunters can choose from a wide variety of weights, designs, construction methods, and ballistic profiles.

That makes the .30-06 easier to configure for different animals and hunting environments.

The .45-70 is more specialized, but its specialization is useful.

If you specifically want a large-diameter, heavy bullet for close-range big game, there aren’t many traditional cartridges that make a stronger case.

Which Is Better for Long-Range Hunting?

The .30-06.

This isn’t really controversial.

The .45-70 can be accurate at distance, but accuracy and trajectory are different things.

A rifle can group very well while its bullets still require substantial elevation correction as range increases.

The .30-06’s faster and more aerodynamic bullets retain velocity better and provide a much more forgiving trajectory.

That makes the .30-06 the better choice for open-country hunting where the distance to the animal can vary substantially.

If long-range capability is high on your list, however, neither cartridge should be selected simply because it appears on a list of “long-range calibers.” Modern cartridges can offer significant advantages in trajectory and wind performance.

Between these two, though, the .30-06 is the obvious choice.

Which Is More Versatile?

The .30-06.

This is where the comparison ultimately becomes easiest.

The .45-70 can handle an impressive range of big game, but it does so best within a particular style of hunting.

The .30-06 has fewer compromises.

It can hunt deer in timber, mule deer in open country, elk in the mountains, and a wide variety of other North American game. It has an enormous selection of factory ammunition and can be configured around different hunting needs.

That’s what makes it such a good general-purpose cartridge.

The .45-70 is the cartridge I’d choose because I specifically want what it does.

The .30-06 is the cartridge I’d choose because I don’t know exactly what I’ll ask it to do.

Which One Should You Choose?

The answer becomes much easier when you forget the cartridge names for a moment and think about your hunting.

If your typical hunt looks like thick timber, short sightlines, lever-action rifles, black bear, hogs, or close-range elk, the .45-70 makes a lot of sense.

If your hunting involves mixed terrain, deer and elk, open country, longer sightlines, or several different species, the .30-06 is the more practical choice.

I’d also consider how much you value the rifle itself.

A hunter who loves a compact lever-action and wants a classic big-bore experience may get considerably more satisfaction from a .45-70 than from a .30-06 bolt gun.

That’s not something a ballistic chart can measure.

.45-70 or .30-06: My Pick

If I could own only one of the two for general North American big-game hunting, I’d choose the .30-06.

It is simply harder to outgrow.

Its trajectory is more forgiving, its ammunition selection is enormous, and it covers more hunting situations without requiring the hunter to work around the cartridge’s limitations.

But if I knew my hunting would consistently take place in thick country and I wanted a short, handy lever-action rifle, I’d be perfectly happy with the .45-70.

In that environment, the .45-70 isn’t a compromise.

It’s arguably the better tool.

That’s what makes this comparison more interesting than a simple “which cartridge is more powerful?” argument.

The .45-70 doesn’t need to beat the .30-06 at long range.

The .30-06 doesn’t need to beat the .45-70 in close-range big-bore performance.

They were built around different ideas.

The .45-70 is the specialist: big bullet, close range, heavy game.

The .30-06 is the generalist: broad game selection, flatter trajectory, and fewer compromises.

For most hunters looking for one big-game rifle, I’d take the .30-06.

For the hunter whose terrain and hunting style specifically favor a .45-70, I’d take the .45-70 without hesitation.
