The 6.5 Creedmoor has become popular and a favorite of many long range shooters. If you are a long range shooter who hasn’t given this cartridge a thought, probably by the end of this review, you will really want to consider going the 6.5 Creedmoor way.

Many have used the 300 Win Mag for decades and they believe that it is the best long range cartridge out there. Yes, it has always been. But the introduction of the 6.5 Creedmoor into play a few years back has completely revolutionized the game. To be fair, let us do a detailed scientific and practical analysis of the 6.5 Creedmoor vs. 300 win Mag.

The 300 Win Mag has a better downrange power than the Creedmoor unfortunately, it burns barrels like crazy. I won't make a final judgment that it is the 6.5 Creedmoor that we need as there are roles that a better downrange power found in the 300 Win Mag will do, but most of the activities we are engaged in can comfortably and more effectively be carried out by the 6.5 Creedmoor, thanks to its accuracy and reasonable power even at long range distances.

The 6.5 Creedmoor Vs 300 Win Mag Ballistics in a Nutshell

  • The 6.5 Creedmoor comes with less recoil as compared to the 300 Win Mag
  • It also comes with shorter actions as opposed to the 300 Win Mag
  • The Cost of purchasing it and running the corresponding guns is lower than the cost associated with the 300 Win Mag
  • The 6.5 Creedmoor comfortably uses lower weight calibers at about 50 and 55 grains, whereas the 300 Win Mag uses up to around 80-grain weights.

Choosing Between the 6.5 Creedmoor Vs the 300 Win Mag

The main two methods followed when making a comparison between the two calibers are:

  • Gather a number of calibers within the two classes, put them together and go ahead to do the testing by yourself as you may desire.
  • Secondly, you have the option of going through a review with calibers that have been tested. Buy these calibers and go ahead to do your verification tests.

The Real Comparison

All in all, for those who may not have the resources, time inclusive, to do their own verification tests, the following summary can guide them to make an informed decision if this argument of 6.5 Creedmoor vs. 300 Win Mag continues to linger on their minds.

a) Elevation Drop

Just from the term, elevation drop refers to the gravitational pull on the bullet towards the earth. Tests and calculations have found out that when making a comparison between the two caliber types, the 6.5 Creedmoor has a flatter trajectory than the 300 Win Mag. In other words, it will not easily be pulled to the earth. This makes it a more accurate thus a better platform choice for the beginners.

b) Sectional Density

This can be defined as the ration of a bullet weight in pounds to the diameter in square inches. The sectional density is an important parameter when it comes to penetration of the target. The higher the sectional density it has, the higher the penetration power thus enabling the bullet to easily be lodged into the animal. Ideally, the 300 Win Mag has a higher sectional density, especially for short-range targets. However, when it gets to long range targets, the 6.5 Creedmoor has a better sectional density. In summary, the Win Mag starts with morale but gets tired faster. The 6.5 Creedmoor may not be very aggressive at first but its force is constantly high for a longer distance and period.

c) Velocity Degradation

This provides an analysis on how fast a bullet velocity is lost over a given distance. With a starting velocity of around 3025 fps and 2950 fps for the 6.5 Creedmoor and the 300 Win Mag respectively, the former will lose about 1200 fps at the 1000 yard mark, with the latter losing about 1253 fps. This implies that the 6.5 Creedmoor remains with a higher velocity over distance, hence more power.

d) Wind Deflection

Whereas the elevation drop is the measure of the vertical bullet displacement, the wind deflection measures the horizontal aspects of the bullet displacement. In other words, how far will your bullet travel right or left away from the main intended original trajectory in the event that there is wind blowing to alter its path? Because of the larger surface area of the 300 Win Mag, the wind affects it more than it affects the smaller 6.5 Creedmoor, another accuracy boosting feature of the latter.

e) Terminal Energy

Terminal energy comes from a combination of the wind deflection, sectional density, elevation drop as well as the velocity degradation. It is also referred to as the kinetic energy at the target. With all these factors combined, the Creedmoor starts with a higher energy level over 1000 yards and ends up losing just 1809 ft/lb energy. On the contrary, the 300 Win Mag ends up losing about 2456 ft/lbs.

The consistency of how the bullet performs on hitting the target within the 1000 yard range is better in the 6.5 Creedmoor category than it is the case with the 300 Win Mag. Within this range, you expect the Creedmoor to break apart so well and cause maximum tissue damage. This means it will be much harder for you to find the most appropriate ammo for long distances within the .300 platform than it will be to find the best ammo within the 6.5-284 platforms.

And though at 1000 yards both the bullets still retain a considerably higher energy, the smaller bullets will have a higher penetration capacity upon hitting the medium sized game. My conclusion would, therefore, be that if you do long range hunting, the chances that you will not only hit the target but also produce a lethal wound are higher when you are using the 6.5 Creedmoor than when you go for the 300 Win Mag brothers.

f) Human Factors

Human factors play an important role in determining how accurate the end result of anything will be. Just as in the case of fuel consumption in a motor vehicle that is highly determined by the human factors, there are human factors that come in to play when it comes to arms and ammo operations.

Though there are so many human factors that are involved, most of them are in tandem within the two platforms. Because of comparison making, only the distinct factors are considered here.

The most important human factor that comes with a difference in the two platforms is the recoil. This is one of the most important ballistic features that will affect the comfort of the shooter as well as interfering with their ability to produce accurate performances. It is no argument that the 300 Win Mag kicks the gun barrel much harder as opposed to the 6.5 Creedmoor. In fact, even before ever shooting the 6.5 Creedmoor, you already know how much rocky the Win Mag can become.

The free recoil, which must never be confused for the felt recoil is constant. On the other hand, the felt recoil varies from person to person. Some console themselves that recoil never affects their abilities to shoot. The truth is that it does. In fact, no sane human being will prefer a gun that comes with felt or free recoil as opposed to that which doesn’t have. The winner when it comes to human factors is, therefore, the 6.5 Creedmoor. And it seems the Creedmoor is winning everything.

User Reviews

In one of the popular ammo forums, a concerned user asked to know which between the 6.5 Creedmoor vs. 300 win Mag would produce the best target shooting within the 600-1000 target range. The answer the user gets is absolute that the 6.5 Creedmoor would be the outright winner not only over the 300 Win Mag but across all the rifles platforms within its range.

The 6.5 cartridge is easier to shoot, not forgetting that it is also economical as its projectiles are much cheaper to buy. The economic aspect of this caliber type is not only because of the cheap cost of buying it but also due to the fact that it uses approximately 40% less powder. This affects both the capital cost as well as the recurrent cost in the sense that the cost and time of cleaning your gun will highly be reduced.


The main reasons why I would advocate for the 6.5 Creedmoor the fact that it is cheaper to buy and to run, its accurately and fatality hits the target even at 1000 yards, which the 300 Win Mag hardly does and it doesn’t burn barrels as can be seen with the other Win Mag option. The only challenge would be to get the right caliber for your rifle. If you therefore can readily access the 6.5 Creedmoor, this ammo comfortably wins the battle between the 6.5 Creedmoor Vs 300 Win Mag.



  1. I continue to dislike these “which one is nest” articles, there are so many variables and then those variables go out the window depending on what kind of shooting people do. For a avg 300 yd shot on elk the 300wm dominates the 6.5 cm, and that’s the last shot I took, practically ripped both lungs apart.

  2. The hell? “its accurately and fatality hits the target even at 1000 yards, which the 300 Win Mag hardly does and it doesn’t burn barrels as can be seen with the other Win Mag option.” When fanboying overrides facts. I have both btw.

  3. I own both and like both but with equal ammo say hornady eldx in both or gmx the 300 wm dominates the creedmoor .love the creedmoor but apples to apples i get 7″ more wind dift and 44″ more drop with the creedmoor and the 300wm has over 100 lb KE more energy at 300 yards than creedmoor has at the muzzle.this article was so funny i thought it was put out by CNN

  4. I particularly like the “elevation drop” section. Sorry to break it to you, but all objects are pulled to to the earth at the same rate. Bullets do not have lift and the explanation provided here is just another example of how misinformation gets spread. Flatter trajectory, ummm, no. If bullet “1” is traveling at a higher speed than bullet “2”, it’s covering more distance in a set amount of time. Gravity has let time to pull it to the earth if you measure drop from point A to point B.
