This is particularly advantageous in long-range shooting, where even small errors in range estimation can result in significant misses.
The 6.5 Creedmoor’s performance in windy conditions is another key strength. The high BC bullets used in the cartridge are less affected by wind drift than bullets with lower BCs. This makes it easier to hit targets in challenging conditions, where wind can significantly impact bullet flight.
Furthermore, while offering outstanding ballistic performance, the 6.5 Creedmoor features moderate recoil. The recoil impulse is more manageable than cartridges like the .308 Winchester, making it easier to maintain sight picture and make follow-up shots. This also makes the rifle more comfortable to shoot over extended periods.
Finally, the accuracy potential of the 6.5 Creedmoor is legendary. The cartridge is known for its ability to consistently produce tight groups at long ranges, making it a favorite among competitive shooters and precision rifle enthusiasts.
Disadvantages of 6.5 Creedmoor
However, the 6.5 Creedmoor is not without its drawbacks. The barrel life of a 6.5 Creedmoor rifle, like that of any high-performance cartridge, is often shorter than that of cartridges like the .308 Winchester. This is because the high pressures and temperatures generated during firing contribute to barrel wear. This means that barrels will eventually need to be replaced more frequently, a factor to consider when weighing costs.
Although the popularity of the 6.5 Creedmoor has soared, availability of ammunition and components has seen fluctuations, though things are rapidly improving.
