The 30-06 bullet typically travels around 2800 fps or 1909 mph, making it a powerful and versatile cartridge widely used in America before the AR15 became popular. According to experts at TRAVELS.EDU.VN, understanding bullet velocity is crucial for hunters and shooting enthusiasts alike. Let’s explore the factors influencing this speed and why it matters.
1. Understanding Bullet Speed: An Overview
Speed can be measured in various ways, but in the US, bullet speed is usually measured in feet per second (fps). Since most people do not have a good feeling about how fast a foot per second is, we have converted all the bullet speeds to miles per hour (mph).
A bullet achieves its highest speed just as it exits the barrel of a gun. After this, gravity and the drag from the air immediately start to slow it down until it falls to the ground or hits something. There are a lot of other factors that affect a bullet’s speed and trajectory once it leaves the barrel. Humidity, ballistic coefficient, and wind all come into play.
So that I won’t bore you with the physics of ballistic calculations, we will just concentrate on muzzle velocity – or the speed of the bullet as it exits the barrel.
The bullet speed you typically see on an ammo box is muzzle velocity. This is measured with a chronograph.
A chronograph has two light sensors set at a known distance apart. It works very quickly to calculate the speed from the time it takes a bullet to pass from one sensor to another.
Chronograph is a useful way to measure bullet speed
A chronograph is an important instrument for people like myself who reload their own ammo. I measure the speed of my bullets at about 4-6 feet from my gun. In my experience, it gives me more accurate readings and protects my chronograph from damage from the muzzle blast. While there is a slight drop in speed, for my purposes of checking the speed of my ammo, it works well.
For the speeds in this guide, I used my Lyman Reloading Handbook as a reference.

2. Typical Velocity of a 30-06 Bullet
A 30-06 bullet typically travels around 2800 fps or 1909 mph.
The 30-06 Springfield was the most popular rifle in America before the AR15. This is probably because it was used by the military for the famous M1 Garand. My reloading handbook lists speeds from 3350 fps (2284 mph) to 2500 fps (1705 mph).
3. Rifle Bullet Speeds Compared
Rifle bullets are the fastest bullets since they have a larger cartridge that can hold more gunpowder. More gunpowder also means more recoil, and rifles are easier than handguns for the shooter to control.

Rifles also have longer barrels than handguns, which increases the bullet’s speed.
| Caliber | Muzzle Velocity (fps) | Muzzle Velocity (mph) |
|---|---|---|
| .22LR | 1070 fps | 730 mph |
| 5.7 x 28mm | 2034 fps | 1387 mph |
| .223 Rem | 3020 fps | 2059 mph |
| .243 | 3100 fps | 2114 mph |
| 5.56 M193 | 3180 fps | 2168 mph |
| 30-06 | 2800 fps | 1909 mph |
| 30-30 | 2200 fps | 1500 mph |
| .308 | 2820 fps | 1922 mph |
| 300 Win Mag | 2960 fps | 2018 mph |
| 7.62 x 39 | 2250 fps | 1534 mph |
4. Factors Influencing Bullet Speed
Below we will review the factors that affect a bullet’s speed. Some have a greater effect than others. We will mainly concentrate on what affects the bullets’ muzzle velocity and not the speed downrange.
All of these are interrelated with a lot of overlap.
To boil it down into one simple statement, a smaller bullet with more gunpowder in the cartridge will travel faster than a larger bullet with less gunpowder.
4.1. Caliber and Cartridge Type
This has the biggest effect on the speed of a bullet. In general, smaller calibers with long cartridges will travel faster than larger calibers with short cartridges. There are two reasons for this.
A 30-30 rifle cartridge compared to a 9mm handgun cartridge
Smaller caliber bullets weigh less. Since they weigh less, it takes less force to make them move. So, they travel faster. Smaller calibers also have smaller bullet sizes.
Rifle Cartridges are usually longer than a handgun and pistol cartridges. This allows more gunpowder to be loaded. More powder means more power to make the bullet travel faster.
4.2. Bullet Weight
Similarly to how a smaller bullet will travel faster than a larger bullet, a heavier bullet of the same caliber will travel slower than a lighter bullet.
Bullet weight is measured in grains. Grains is a very old unit of measure and one of the smallest. Each caliber of bullet will usually have different bullet weights to choose from.
For years I experimented with my handgun competition ammo to find what worked best for me. For 9mm, there are 90, 115, 125, 135, and 147 grain bullets available.
For example, I can load a 115-grain bullet to achieve a certain speed. If I simply change to a 135 or 147 grain bullet, the resulting speed will be slower.
4.3. Gun Powder Amount and Type
It is obvious that the more gunpowder there is in a cartridge, the faster a bullet will go. But the type of powder also makes a difference.
The type of gunpowder used is an important consideration that affects how fast a bullet travels
While the speed gunpowder burns is a complicated subject, we can say that in most cases, a slower burning powder in a rifle will make the same bullet go faster than a faster burning powder. This is because as the bullet travels down the barrel, the gunpowder continues to burn and continues to accelerate the bullet.
This is mainly useful for people who reload their own rifle ammo for competitions. Handgun shooters and anyone who buys their ammo really don’t need to worry about the type of gunpowder. Often, ammo manufacturers don’t disclose the type of gunpowder they use.
4.4. Barrel Length
Barrell length will affect how fast a bullet travels. As we mentioned earlier, as soon as a bullet leaves the gun barrel, it begins to slow down.
A bullet fired from the longer barrel will travel faster than the same bullet fired from the shorter barrel
As the bullet travels down the gun barrel, it continues to accelerate as the combustion gasses from the burning gunpowder expand. This is dramatically more true between a handgun and a pistol.
Some cartridges, like 9mm and 5.7mm, have guns made for them in handgun and rifle configurations. The same bullets shot from the rifle will be faster than the bullets from the handgun.
But, even between rifles and handguns themselves, there can be different barrel lengths. For example, common rifle barrels range from 16” to 20”, while handguns usually range from 3” to 6”.
4.5. Bullet Type
While not as much of a factor inside the barrel as it is after the bullet leaves the barrel, bullet type and shape affect the speed of a bullet.
As the bullet travels down the gun barrel, it fits very tightly. There is a considerable amount of friction between the bullet and the inside of the barrel. More friction means a slower bullet.
Most bullets are coated with either a copper or polymer coating to reduce friction. This helps lubricate and allows them to slide through the barrel with less friction. A pure lead bullet with no coating will travel slower because of the added friction.
Once the bullet is in the air, a more aerodynamic bullet shape will travel farther than a less aerodynamic bullet. For example, a pointed boat tail bullet will travel farther than a hollow point bullet (but I digress).
5. Why Bullet Speed Matters
There is always a great debate over what is better for hunting and self-defense. A larger bullet or a faster bullet. Well, as with most answers to a debatable question, it depends.
Basic physics gives us a simple equation. Force = Mass * Velocity(squared). We can consider this for a bullet, with the mass and speed of the bullet exerting a force on a target.
Just looking at this, we can see that mass certainly has an effect on the force. But the speed has a much greater influence since it is squared.
However, there is a practical aspect to consider. You can’t just load up a .223 cartridge with a ton of powder to make it super-fast and deliver more force than any bullet known to man. The action and the barrel of a gun can only withstand so much pressure.
Using this equation, you can see why the US military adopted the 5.56 cartridge as the choice round. It is a smaller caliber but was designed to be faster than most other cartridges. In the end, it will deliver more force to the target.
6. Exploring 30-06 Cartridge Variations
The 30-06 Springfield cartridge is known for its versatility, accommodating a range of bullet weights and designs. According to “American Rifleman,” bullet weights typically vary from 110 to 220 grains, each suited for different purposes, from varmint hunting to taking down large game.

| 220 | 2400-2600 | Extremely Large Game, Dangerous Game |
6.2. The Role of Bullet Design
Bullet design significantly influences its ballistic coefficient and how it performs upon impact. Spitzer bullets, with their pointed tips, are favored for long-range shooting due to their aerodynamic efficiency. Soft-point bullets, designed to expand upon impact, are preferred for hunting to deliver maximum energy transfer to the target.
