The 30-30 Winchester and 30-06 Springfield are two of the most popular big game hunting cartridges in North America and have been in production for well over a century. One was forged on the battlefield while the other cut its teeth in the woods, but both are nothing short of Second Amendment legends.

Both rifle cartridges have a long and illustrious heritage in the field, but they each fill their niche when it comes to hunting.

The 30-06 is well known for its exceptional range, stopping power, and versatility. In contrast, the 30-30 is perhaps the oldest hunting cartridge still in production and has arguably put more venison on the table than any other cartridge in history.

The 30-06 and 30-30 have remained relatively unchanged over the past 100 years, which speaks volumes to their effectiveness and reliability, especially in deer hunting.

In this article, we will take a deep dive into the history, ballistics, and benefits of each cartridge so you can make a more informed decision on your next hunting rifle. Although there’s no way to declare a “winner” between these two rifle cartridges, we can evaluate the advantages and disadvantages of each.

The Difference Between .30-30 and .30-06

When it comes to 30-06 vs 30-30, there are considerably more differences than similarities. The fact that both cartridges fire the same 30 caliber bullets is one of the few similarities between the two as each cartridge was designed to fill a different role.

Released in 1895, the 30-30 was specifically designed to be a sporting cartridge and used in lever-action rifles. It is a rimmed, centerfire rifle cartridge that has low recoil that allows for quick follow-up shots. This combination is extremely potent in a lever-action rifle as you can easily fire multiple rounds in quick succession.

One downside to a lever action is the need for a tubular magazine. This means that bullets are loaded into the magazine one at a time, end-to-end. Therefore, the bullets used for a lever-action rifle must either be a flat point design or a round nose. If a pointed, Spitzer-style bullet was used it could impact the primer of the round in front of it in the magazine. This could set off a chain reaction that would seriously damage the firearm and shooter.

In contrast, the 30-06 was developed as an instrument of war and carried the U.S. Military to victory in both World Wars, Korea, and to a lesser extent, Vietnam (before being replaced by the 308 Winchester). It is a bigger, heavier cartridge that was designed initially for bolt action rifles and then later was adapted to the semi-automatic M1 Garand.

Although the genesis of each cartridge was significantly different, their potency against North American game animals is second to none.

Cartridge Specs

When analyzing rifle cartridges, it’s prudent to look at the cartridge case to ascertain what differences exist inside the cartridge.

30-30 vs 30-06 dimension chart

The first thing that you should notice is that both rifle cartridges fire the same bullet diameter, 0.308”. This is about the only similarity we will see when it comes to 30-30 vs 30-06!

The first major difference you’ll notice is the case length as the 30-06 dwarfs the 30-30 by over 0.4”. This drastic difference means that the action type for each cartridge will be different. As the 30-30 is a shorter case, it will fit into a short action rifle. This means that the distance the bolt needs to be thrown to eject the spent case will be shorter.

By contrast, the 30-06 has a longer case and fits into long action rifles.

In theory, a short action and shorter case “could” allow for faster follow-up shots as it takes less movement to eject a fired cartridge case from the chamber. However, with a little time working on your bolt throw at the range, most deer hunters will not notice any difference between a short action vs long action rifles in terms of reload speeds.

The next major difference is the case capacity of each cartridge. The 30-06 is a cavernous case that can hold 68 gr of propellant, while the 30-30 has about 30% less case capacity at 45 gr. This means that the 30-06 will be able to fire heavier bullets at a higher muzzle velocity than the 30-30.

Lastly, the base diameter for 30-30 is considerably smaller than 30-06 (0.422” vs 0.471”, respectively). This relates to both case capacity and the SAAMI spec maximum pressure. The 30-30 can withstand about 33% less pressure at 42,000 PSI as compared to the 30-06 at 60,200 PSI.

All that case capacity comes at a cost though…And that cost is felt recoil.

Recoil

When it comes to recoil, the 30-30 has considerably less felt recoil than the 30-06. The 30-30 was specifically designed to have less recoil than other hunting rounds of the day, such as the 45-70 Government.

As both cartridges fire the same bullet, we can do an apples-to-apples comparison. For this example, we will examine the Remington Core-Lokt with a 150-grain bullet as this is a popular loading for both cartridges.

Assuming a 7-pound rifle, a 150-grain Remington Core-Lokt fired in 30-06 will have a felt recoil of about 23 ft-lbs slapping your shoulder. In contrast, the 30-30 will only impart about 14 ft-lbs of force into the shooter. And trust me, when you shoot these two rifles side-by-side, you can tell the difference!

The reason for this drastic difference is due to the differences in case capacity and muzzle velocity. As the 30-06 has a longer case length and higher case capacity, the addition propellant will allow for higher muzzle velocity when compared to the 30-30, even though the bullet weight is the same.

In the example above, the muzzle velocity 30-06 is 2,910 FPS and 2,390 FPS for 30-30 according to Remington’s ballistic data.

Newton taught us in high school physics that every action has an equal and opposite reaction. Henceforth, as the bullet fired from the 30-06 has more force used to push it out the barrel at a higher velocity, it, therefore, must push back on the shooter equally hard.

Therefore the 30-30 will always have less recoil than 30-06 because 30-30 has a shorter case and less case capacity.

But does this matter? For many marksmen and hunters, it won’t.

As hunters rarely have long strings of fire, it is unlikely that recoil will be much of a deciding factor for seasoned whitetail stalkers.

However, for new or inexperienced shooters, heavy recoil can cause them to throw their shots as they anticipate the recoil. Therefore, for newer or recoil-sensitive shooters, the 30-30 is the obvious choice. But for those marksmen who have trained their fundamentals of shooting, the recoil of the 30-06 should not be an issue.

Trajectory

Trajectory is how we quantify a bullet’s flight path to its target measured in inches of bullet drop. As a bullet travels downrange, it is constantly being pulled back towards the earth due to gravity. And in terms of long range shooting, a flatter trajectory is preferred.

When comparing the 30-06 and the 30-30, the 30-06 reigns supreme when it comes to trajectory. Take for example the 150-grain bullet we discussed earlier, at 400 yards the 30-06 will experience a reasonable bullet drop of -19” while the 30-30 is crashing back to the earth with a bullet drop of -63”. That’s a difference of 44”, which is 3.66 feet. That can mean the difference between nailing a double lung shot on a whitetail deer at range or sailing the round well below his belly (or worse, injuring the animal).

This is primarily due to the bullet designs dictated by the tubular magazine of the 30-30. As pointed, more aerodynamic bullets cannot be used in the 30-30, less aerodynamic bullets like flat points or round noses must be utilized. These bullets will hemorrhage FPS downrange at a ridiculous rate. As the bullets slow down, the forces of gravity and air resistance have a more profound effect on their trajectory.

This makes the 30-06 the preferred cartridge for long range target shooting or hunting shots as it has a flatter trajectory and more aerodynamic bullets that maintain their velocity for greater distances.

Accuracy

Accuracy is a very subjective comparison point as it depends more on the shooting platform and the individual shooter more so than the cartridge itself.

There’s no denying that the 30-30 is an accurate cartridge, given its whitetail slaying legacy. However, we must call into question the effective range of the 30-30 and its general trajectory (as discussed above).

Looking at the ballistics tables below, we can see that within 200 yards there is very little difference in the trajectory between 30-30 and 30-06. However, the further you go downrange with the 30-30 the worse things get.

This is due to the massive loss in velocity experienced by the less aerodynamic 30-30 as it travels to the target.

The range at which a bullet goes below the speed of sound is referred to as its supersonic limit. For the 30-30, this is around 400 yards…that’s not very good compared to the 30-06 that can remain supersonic up to just over 1000 yards.

Once a bullet dips below the speed of sound, accuracy suffers considerably as the bullet is affected by environmental conditions (gravity, wind, air resistance) more.

Therefore, within 200 yards you should experience virtually no difference in accuracy. However, as the 30-30 begins to slow down faster once it passes 200 yards, the bullet drop calculations become considerably more difficult. This makes it more difficult to maintain accuracy over 300 yards for the 30-30.

At ranges over 300 yards, the 30-06 will be the more accurate cartridge. And the snipers of WWII will attest to that!

Ballistic Coefficient

Ballistic Coefficient (BC) is a numerical representation of how well a bullet resists wind and air resistance. It’s a measure of how aerodynamic a bullet is, a high BC is preferred and means the bullet will buck the wind easier.

The way a BC is calculated is rather complicated and irrelevant for this article, however, heavier bullets will typically have a higher ballistic coefficient.

As I’m sure you’ve guessed by now, the bullet design for 30-30 plays a huge role in its Ballistic Coefficient as they are generally less aerodynamic.

And this shows in the numbers as the 30-06 absolutely runs away with it in terms of BC. On average, 30-06 will have an SD of around 0.427 compared to 0.231 for 30-30, which is just short of being a 2x difference.

The 30-06 simply dominates in terms of Sectional Density, even though 30-30 fires the same bullet diameter as 30-06.

Sectional Density

Sectional Density (SD) is the measure of how well a bullet penetrates a target. This is extremely important when hunting big game, as you need a bullet that can punch through thick hide, bone, and sinew.

Sectional density is calculated by comparing the bullet weight and the bullet diameter, the higher the number the more effective it will be at penetrating a target. The higher the SD the deeper the bullet will penetrate the target.

As the 30-06 and 30-30 shoot the same caliber bullet, the only determining factor is bullet weight. If more penetration is needed, a heavier bullet should be used.

As such, Sectional Density is virtually identical between 30-06 and 30-30. Furthermore, it is unlikely a whitetail deer will be able to feel any minuscule differences in SD between these two hunting cartridges.

Hunting

And now we come to the biggest comparison of them all, 30-30 vs 30-06 for hunting.

When it comes to hunting, shot placement is the key to successfully and humanely harvesting a game animal. It doesn’t matter how many ft-lbs your bullet has, the exotic moon rock extruded propellant your handloads use, or what type of HALO-inspired projectiles you are using if your shot placement is terrible.

Effective practice at the range is the key to accuracy, so make sure that you can put the bullet where it needs to go when the moment of truth arrives.

Phew! Ok, we got that out of the way, now let’s talk hunting.

There’s no denying that the 30-30 is a North American deer hunting all-star cartridge as it’s been consistently sending whitetail to the freezer for well over a century.

However, there is one thing to consider when using 30-30 for hunting, and that’s its effective range.

As a rule of thumb, 1,000 ft-lbs of energy is needed to effectively harvest a deer. After looking at the 30-30 ballistics table below, I’m sure you can see the issue.

The 30-30 starts to come dangerously close to 1,000 ft-lbs of energy once it crosses the 200-yard marker. The one exception to this is the Hornady LEVERevolution. The LEVERevolution bullet uses an extremely flexible elastomer tip that is safe to use in tubular magazines. This allows Hornady to use more aerodynamic bullets for 30-30, extending its effective range to about 300 yards.

And how about the 30-06? Pfft! 200 yards is mere child’s play!

The 30-06 will still be way over 1,000 ft-lbs of force even past 500 yards, greatly extending the range of your hunting rifle.

But the big question is: “Does effective range really matter?”

And the answer is, “It depends on where you want to go deer hunting.”

If you plan on hunting out of a tree stand in a heavily wooded area where 100 yards is considered a long shot, then 30-30 will be more than enough to meet your needs. However, if you’re going to be hunting mule deer up in Montana where 400+ yard shots are commonplace, then you’ll need to bring your favorite 30-06 hunting rifle to ensure you have enough range to claim your trophy.

Now let’s talk large game, and by that, I mean elk, black bear, and moose.

For black bear, conventional wisdom states that 1,000 ft-lbs is needed for a clean kill, the same as whitetail. For this, 30-30 and 30-06 are both sufficient provided you do your part.

However, elk and moose are something else entirely. For these large game animals, you’ll need to hit with 1,500 ft-lbs of energy for elk and 2,200 ft-lbs for moose. By these numbers, you’ll need to be within 100 yards to take an elk with 30-30. For moose, you’ll need to be at point blank range with a bit of a sprint towards the moose for some extra FPS (that’s not advisable).

However, this is where the numbers somewhat diverge from reality and actual field reports. Many Canadian hunters report taking moose with 1 shot of 30-30 every year. But by the numbers, this shouldn’t happen. Along that same line, I’m sure you’ve heard the stories of deer being taken with .22 LR as well.

When you hear stories like this, you must remember that it all comes down to shot placement. If you know exactly where you need to hit and you are accurate enough to do it, then I have no doubt you can take a moose with 30-30.

However, just because you “can” do a thing, doesn’t mean you “should” do that thing.

To that end, many states and territories have regulations requiring the use of specific calibers on certain large game animals. Always ensure that you are following all local and state hunting regulations whenever you head out into the woods (and yes, that means caliber restrictions too).

When hunting big game, the 30-06 is a clear choice as it offers the range, penetration, and stopping power you need to effectively harvest these large game animals. For these hunts, I’d recommend the 180 grain Barnes TTSX or Nosler Accubond Trophy Grade ammo for best results.

To summarize, the 30-30 is an extremely effective hunting round and is an excellent low recoil option for whitetail deer, mule deer, feral hogs, and black bears across North America. Engagement ranges should be under 200 yards to ensure you have enough ft-lbs of energy to harvest the animal humanely.

For large game, like elk and moose, the 30-06 is preferred as it brings more stopping power and FPS that allows you to engage at longer distances. Keen marksmen have claimed these game animals using the 30-30, but this is not recommended as it lacks the necessary ft-lbs of force to harvest larger game consistently and humanely. Furthermore, many local hunting regulations prohibit it.

Reloading

When it comes to reloading and crafting your own handloads for 30-06 and 30-30, you have many different bullets and powders at your disposal.

Both cartridges require a large rifle primer and they both fire the same 30-caliber bullets like the 308 Winchester and 300 Win Mag. Therefore, you could potentially craft handloads for 4+ different calibers and only have to purchase one caliber of bullet and primer size, which is very helpful if you like to stock up on reloading components.

All the major bullet manufacturers have a plethora of 30 caliber projectiles for you to choose from in various bullet weights and designs. Manufactures such as Hornady, Nosler, Barnes, Federal, Sierra, and Speer are more than happy to keep your reloading table stocked with 30-cal bullets that will make short work of any game animal you’re aiming to hunt.

Reloading for 30-06 and 30-30 is a breeze and you can really dial in your handload to get that sub-MOA accuracy you need to win bragging rights at deer camp later this hunting season!
