.270 Winchester vs .308 Winchester
Contrasting the .270 Winchester vs .308 Winchester highlights two classic hunting cartridges with different approaches to big game performance. The .270 Winchester (130gr Extreme Point at 3060 fps) delivers higher energy, maintaining 2516 ft-lbs at 50 yards compared to the .308 Winchester's (150gr Extreme Point at 2820 fps) 2433 ft-lbs. Both cartridges demonstrate substantial penetration for hunting applications, with the .270 Winchester reaching 45.8-46.2 inches and the .308 Winchester achieving 31.5-31.8 inches, both well beyond defensive requirements. The recoil comparison slightly favors the .308 Winchester, generating 22.2 ft-lbs of recoil energy versus the .270's 25.01 ft-lbs. While the .270 Winchester provides higher velocity and marginally better energy retention, the .308 Winchester's widespread military heritage and ammunition availability make it a popular choice for hunters seeking proven big game performance. Remember that performance varies considerably with different ammunition selections and firearm platforms, so these figures represent typical hunting loadings rather than definitive performance benchmarks.
