.223 Remington vs .243 Winchester
Studying the .223 Remington vs .243 Winchester comparison demonstrates the significant performance difference between these popular rifle cartridges. The .243 Winchester (95gr Extreme Point at 3100 fps) delivers substantially higher energy, maintaining 1855 ft-lbs at 50 yards compared to the .223 Remington's (64gr Extreme Point at 3020 fps) 1155 ft-lbs. Both cartridges demonstrate deep penetration characteristics well-suited for hunting applications, with the .243 Winchester reaching 41.9-42.3 inches and the .223 Remington achieving 27.0-27.4 inches, both far exceeding defensive requirements. The recoil comparison strongly favors the .223 Remington, generating 5.19 ft-lbs of recoil energy versus the .243's 13.19 ft-lbs. Despite similar muzzle velocities, the .243's heavier bullet weight provides significantly greater energy transfer and penetration for medium game hunting scenarios. Remember that performance varies considerably with different ammunition selections and firearm platforms, so these figures represent typical hunting loadings rather than definitive performance benchmarks.
