7mm-08, as well as 6.5 Creedmoor, has developed a great position in the department of ammunitions considered the best cartridge discovery ever. Although both of the cartridges possess a lot of similarities the differences between them still cannot be denied at any cost. There is a lot of misconception among the hunters regarding the functions and structure of 6.5 Creedmoor and 7mm-08 that should be cleared and understand all the strengths as well as weaknesses if one wants to use the ammunition efficiently.
As good and efficient ammunition is as important as a good gun, so hunters must get as much information about the ammunitions and then chose accordingly according to their requirements to get the desired results while hunting. Also, during the shooting competitions, there is no space for a mistake so you should preferably choose the best ammunition for the task.
Historical Background of 6.5 Creedmoor and 7mm-08:
All of the competition of accuracy among the cartridges started with a .308 Winchester that developed a legendary reputation in the ammunition world with its power and accuracy and competition started wildcatter and gun designers started to modify the .308 Winchester to develop more specialized cartridges.
7mm-08 cartridges seemingly 7mm-08 ballistics are also a derivation of .308 essentially a modified .308 Winchester case necked down to shoot 7mm bullets. While talking about .308 vs 7mm-08, a 7mm-08 Remington provides higher velocity, less recoil, a flatter trajectory, and effectively more resistance to wind drift. Although .260 Remington, .338 Federal, and .358 Winchester are all derived from .308 Winchester and are somehow a modified version of it when considering 260 Remington vs 7mm-08 cartridges, 7mm-08 has proved to be very popular among the hunters for a very long time till the 6.5 Creedmoor came into existence.
6.5 Creedmoor was developed by Dave Emary and Dennis DeMille of Hornady Manufacturing to gain more efficiency for high-power rifle shooting competition. With a relatively fast 1:8″ rifle twist rate, an efficient 6.5 Creedmoor load shoots 140-grain bullets at about 2700 fps providing extreme accuracy, minimal recoil, and uses high BC bullets that retain energy and resist wind drift.
Either it is 6.5 Creedmoor vs 243 or 6.5 Creedmoor vs 7mm, the 6.5 ballistics provide more resistance to wind drift, less recoil, and a flatter trajectory as compared to the .308 Winchester. Although, both of the cartridges are derived from .308 Winchester yet are modified in a way that has made them very popular and efficient.

Similarities Between 6.5 Creedmoor and 7mm-08
From the above-mentioned history, we can see that both 6.5 Creedmoor and 7mm-08 are related to history as both are modified from .308 Winchester. This derivation gives them an edge on a lot of similarities that they possess. As 7mm-08 Remington is descended from .308 Winchester and is much closely related to .260 Remington that is also derived from a .308 cartridge.
Also based on the length of .308 Winchester, the 6.5 Creedmoor is a modified version of the 3.0 Thompson center.
Therefore, a lot of similarities can be observed between both of the ammunitions including their recognition for accuracy and precision. Both of the cartridges are also budget-friendly and possess the ability to fit into short-action rifles. Moreover, both have rimless, bottleneck case types.
6.5 Creedmoor vs 7mm-08: Cartridge sizes
Both of the cartridges possess a very similar size with similar case lengths and overall lengths. Moreover, both of the cartridges also tend to have the same rim diameter of .473″. The only difference that can be analyzed regarding the size of the cartridges is the size of the bullets. A 6.5 Creedmoor uses a bullet of diameter .264″ (6.5 mm) while the diameter of the bullets used by 7mm-08 Remington is .284″ (7mm). But an overlap in the weights of the bullets used by both cartridges can be observed. The 6.5 Creedmoor utilizes bullets in a grain range of 95-160 grain range while that utilized by 7mm-08 Remington ranges from 120 -160 grain range.
A frequently asked question is that ‘how big is 7mm?’, the answer is that it has an overall length of 3.29.

6.5 Creedmoor vs 7mm-08 Cartridge Differences
|Cartridge||6.5 Creedmoor||7mm-08 Remington|
|Free Recoil Energy||18.51ft-lbs||22.38ft-lbs|
Both of the cartridges have almost similar trajectories but the 7mm-08 Remington retains more kinetic energy than the 6.5 Creedmoor while 6.5 Creedmoor has less recoil and fires smaller diameter and more aerodynamic bullets.
7mm-08 Remington has a major advantage over 6.5 Creedmoor in terms of bullet diameter as it uses bullets with larger diameters. The .284″ diameter bullets used by the 7mm-08 cartridges have more cross-sectional area than the .264″ diameter bullets used by the 6.5 Creedmoor. Moreover, a bigger bullet tends to cause more tissue damage and create a bigger hole. But when the facts regarding the more kinetic energy downrange of 7mm-08 are considered, it is believed that t is specifically helpful if larger hunting games.
Although, the lower diameter bullets used by 6.5 Creedmoor help manufacture bullets that are not heavy with a better aerodynamic projectile motion and more wind drift resistance. Moreover, 6.5 Creedmoor has an edge over the 7mm-08 in bullet sectional density especially in the case of heavier bullets. Sectional density (SD) is the measure of the ratio of the diameter of a projectile to its mass. Therefore, a projectile with ab higher sectional density can penetrate deeper than the projectile with a lower sectional density. So, the higher sectional density bullets used by 6.5 Creedmoor helps in penetration to help the cartridge punch above its weight.

Considering the above-mentioned analysis of 6.5 Creedmoor, it provides excellent penetration, less recoil, and longer shooting range. It also tends to give maximum average pressure in a better way. Moreover, it is ideal for small-framed shooters and may not be as efficient in big hunting. Also, it provides a lower velocity than the 7mm-08 Remington.
