This video from Banana Ballistics provides a detailed comparison of the .308 Win, .30-06 Springfield, and .300 Win Mag calibers through various barrier tests. The host, demonstrating high authority and an analytical approach, uses a Garmin Xero C1 Pro chronograph to record velocity data. Key findings include the .300 Win Mag's superior penetration against heavy steel, while the .308 Win shows remarkable efficiency.

Quick Summary

The .300 Win Mag demonstrated superior penetration against heavy steel, piercing a 1/2-inch plate, while .308 Win and .30-06 did not. However, the .308 Win showed remarkable efficiency, matching .30-06 performance with less powder. Velocities recorded were 3257 fps for .300 Win Mag, 2987 fps for .30-06, and 2964 fps for .308 Win.

Frequently Asked Questions

How do .308 Win, .30-06 Springfield, and .300 Win Mag compare in penetration tests?

.300 Win Mag shows superior penetration, notably piercing a 1/2-inch steel plate. The .308 Win and .30-06 Springfield, while creating significant craters, failed to penetrate the same steel plate in the video's tests.

What were the measured velocities for .308 Win, .30-06 Springfield, and .300 Win Mag?

Using a Garmin Xero C1 Pro, the .300 Win Mag averaged 3257 fps. The .30-06 Springfield averaged 2987 fps, and the .308 Win averaged 2964 fps, both using 147 gr FMJ projectiles.

Does the .300 Win Mag always outperform .308 Win and .30-06?

Not necessarily. While the .300 Win Mag excels in heavy steel penetration, the .308 Win demonstrates remarkable efficiency, matching .30-06 performance with less powder in some tests, and all three struggled against 6 inches of sand.
