270 Win vs 308 Win: ONE Clear Winner On Mild Steel
This video compares the .270 Winchester and .308 Winchester cartridges by testing their penetration on mild steel targets. While the .270 Win has a higher velocity and sectional density, the .308 Win ultimately penetrates a 1/2 inch steel plate due to its greater kinetic energy. The test highlights that kinetic energy is a crucial factor for steel penetration, not just velocity or bullet weight alone.
