If you are researching on short action rifles, then you might find some of them using 6.5 Creedmoor, but others go with 308 Winchester. Are they different much?
While the 308 Winchester is ideal and reliable for mid-range in term of a drop, the 6.5 Creedmoor is lighter and popular for medium to long range shooting. However, we cannot conclude one is better than another only by this.
You can find many biased discussion on the internet, but in this article, we want to offer something more valuable to our readers. We will compare the two types based on their
- Ammo, rifle selection, and availability
- Ballistic performance
- Trajectory drop and Recoil
- Barrel life
- Subsonic transition
Our goal is to provide everything you need to make the decision yourself. Now let’s get started.
When looking at these two cartridges, you will notice that they are almost identical, and both are extremely solid and reliable. However, there is a slight difference in the making.
The case design of the 6.5 Creedmoor is based on that of.30 TC. This is what you need to know if you are going to reload your rifle with this brass.
Now take a closer look at the two cartridge shoulder angles. Do you see the 308 Winchester has a blunt shoulder at 20 degrees, while at 30 degrees, the 6.5 Creedmoor has a sharper one?
In long range shooting, It is crucial to know that the shaper the shoulder, the more accurate the shot, and this also explains why the 6.5 Creedmoor generally last longer than the other.
However, the bad news is that this 6.5 Creedmoor brass is very limited. There are only a few companies such as Norma or Hornady offering this.
The 308 Winchester, on the other hand, is available nearly everywhere, and it also proves itself to provide more reliable and accurate. If you plan to reload your semi-automatic, the 308 Winchester brass is your best option.
Ammo, Rifle Selection, and Availability
When we say that the 6.5 Creedmoor brass is quite limited, we don’t mean it’s hard to obtain. When it comes to availability, the research shows that these two cartridges are easy to find.
You will be surprised to see that sometimes the 6.5 Creedmoor is offered at a lower price than the other, and it’s not so often in the sale at the local hunting stores.
However, you can buy them on the internet at online retail stores, but you should note that the price of them are various from different regions.
The 308 Winchester is rather easy to look for because it is favorable among hunters. The cartridge is continuously ranked as one of the best sellers in the US. You can find them at every store in your area, but it’s slightly more expensive than the 6.5 Creedmoor.
The 6.5 Creedmoor has an increment in popularity recently, but the .308 Winchester still hold the advantage and get stocked on every gun shop.
Besides, another reason why shooters favor the .308 Winchester than another is because it is compatible with almost every bolt action rifle.
While both of these two cartridges are designed to suit for hunting small to medium size animals such as mule deer or whitetail deer, the .308 Winchester particularly goes well with a lot bigger game.
If you prefer to use a semi-automatic rifle, you cannot go wrong with the .308 Winchester because there are many good rifles out there available for this cartridge.
When it comes to long-range shooting, the 6.5 Creedmoor has been outstanding for decades comparing to its counterpart, and it also provides better resistance wind drift.
However, there is no best choice of cartridge for shooting scenarios. We just consider the pros and cons of each and make a decision.
The 6.5 Creedmoor might give you a better result in long-range shooting, but the .308 Winchester brass is heavier which is an advantage regarding kinetic energy.
Trajectory Drop and Recoil
The 6.5 Creedmoor outperforms its counterpart in this respect. Trajectory drop of a bullet occurs as a result of gravity and air friction.
Being with faster velocity and lighter weight than the .308 Winchester, the 6.5 Creedmoor no doubt has less influence on its bullet path.
Every rifle has recoil, and it is clear that the heavier the bullet, the more recoil you will get.
For that reason, the .308 Winchester will give you more recoil than the other. A hard kickback from your rifle is not a pleasant experience.
Barrel life is one important thing you need to consider. It tells you how many shots you can fire before losing accuracy.
A high-quality barrel with well-maintain can expect to last up to more than 5000 rounds.
In this case, we believe that the 308 Winchester has a longer lifespan than the other due the high speed and small bore. Hunters do not usually see the 6.5 Creedmoor last more than 2,500 – 3000 rounds so far.
A subsonic transition is how well the bullet maintains its stability when it enters transonic speed and becomes subsonic in long range shooting.
The good news is that both of two brasses perform excellently at maintaining its speed. However, the 6.5 Creedmoor shows significant advantage than the 308 Winchester when it enters subsonic velocities.
It is not easy to say which one is the best for every shooting scenario as each of them has its advantage and disadvantage.
