.243 Winchester vs 6.5mm Creedmoor
Studying the .243 Winchester vs 6.5mm Creedmoor reveals two modern precision-oriented cartridges with different approaches to long-range performance. The 6.5mm Creedmoor (125gr Extreme Point at 2850 fps) delivers higher energy, maintaining 2121 ft-lbs at 50 yards compared to the .243 Winchester's (95gr Extreme Point at 3100 fps) 1855 ft-lbs. Both cartridges demonstrate substantial penetration for hunting applications, with the .243 Winchester reaching 41.9-42.3 inches and the 6.5mm Creedmoor achieving 36.1-36.4 inches, both well beyond defensive requirements. The recoil comparison favors the .243 Winchester, generating 13.19 ft-lbs of recoil energy versus the 6.5mm Creedmoor's 16.95 ft-lbs. While the .243 starts with higher velocity, the 6.5mm Creedmoor's heavier bullet and superior ballistic coefficient provide better energy retention and long-range ballistic performance, making it increasingly popular for precision shooting applications. Remember that performance varies considerably with different ammunition selections and firearm platforms, so these figures represent typical hunting loadings rather than definitive performance benchmarks.
