The general size (OAL) of the .243 Winchester cartridge can be necessary by way of journal compatibility.
Let’s immediately evaluate the scale of those two cartridges, making issues simpler to know.
- 6.5 Creedmoor:
- Bullet Diameter: 6.5mm (.264 inches)
- Case Size: Roughly 1.92 inches
- Total Size (OAL): Roughly 2.82 inches (varies with bullet)
- .243 Winchester:
- Bullet Diameter: 6mm (.243 inches)
- Case Size: Roughly 2.045 inches
- Total Size (OAL): Roughly 2.71 inches (varies with bullet)
From a easy measurement perspective, the 6.5 Creedmoor certainly makes use of a bigger bullet diameter. Though the case lengths and total lengths are comparable, the 6.5 Creedmoor fires a bullet that’s barely bigger in diameter than the .243 Winchester. Nonetheless, merely judging based mostly on this dimension can be an excessively easy method.
Ballistic Efficiency Past Measurement
Measurement alone, nevertheless, would not inform the total story. To actually perceive these two cartridges, we should take into account their ballistic efficiency, which is essential to creating an knowledgeable resolution.
Bullet weight is a crucial element of a cartridge’s efficiency, considerably affecting the bullet’s trajectory, retained power, and its capabilities at lengthy distances.
The 6.5 Creedmoor is usually used with bullets that weigh between 120 and 150 grains. This can be a appreciable issue when put next with .243 Winchester. The extra mass enhances sectional density and ballistic coefficients, leading to better power retention and resistance to wind drift.

The .243 Winchester is greatest suited to use with bullets starting from 55 to 105 grains. The lighter bullets will be accelerated to unbelievable velocities, resulting in extraordinarily flat trajectories over shorter distances, a bonus for varmint searching.
Muzzle velocity and power are two key efficiency points that outline a cartridge’s capabilities. Muzzle velocity is the velocity at which a bullet exits the barrel, measured in ft per second (fps). Muzzle power is the kinetic power of the bullet on the muzzle, measured in foot-pounds.
The 6.5 Creedmoor, because of its bigger case capability and the power to make use of heavier bullets, sometimes produces a muzzle velocity within the vary of two,600 to three,100 fps. The muzzle power will fluctuate based mostly on the particular load.
The .243 Winchester, utilizing its lighter bullets and a barely smaller case capability, produces excessive muzzle velocities, often between 3,000 and three,900 fps.
The ballistic coefficient (BC) is a quantity that describes how successfully a bullet resists air resistance. The next BC signifies that the bullet is healthier at retaining its velocity over distance, resulting in flatter trajectories, diminished wind drift, and higher long-range efficiency.
The 6.5 Creedmoor sometimes has larger BCs than the .243 Winchester, due to its bigger diameter and talent to accommodate longer, extra streamlined bullets. This is likely one of the keys to the 6.5 Creedmoor’s reputation for long-range capturing.
