This video conducts a rigorous barrier test comparing .308 Win, .30-06 Springfield, and .300 Win Mag. While all calibers performed similarly through lumber, steel, and sand, the .300 Win Mag eventually proved superior in penetrating a 1/2-inch steel plate. The .308 Winchester demonstrated remarkable efficiency, matching .30-06 performance with less powder.

Quick Summary

The .300 Win Mag proved superior in barrier penetration, being the only caliber to pierce a 1/2-inch steel plate. The .308 Winchester showed impressive efficiency, matching .30-06 performance with less powder, averaging 2964 fps compared to the .30-06's 2987 fps.

Frequently Asked Questions

Which rifle caliber performed best in the barrier tests?

The .300 Win Mag ultimately proved superior, being the only caliber to successfully penetrate a 1/2-inch mild steel plate. While all calibers performed similarly through initial barriers like wood and sand, the magnum's power became evident against tougher materials.

How did the .308 Winchester compare to the .30-06 Springfield?

The .308 Winchester demonstrated remarkable efficiency, achieving nearly identical performance to the .30-06 Springfield in barrier tests despite using significantly less powder. Their average velocities were very close, with the .308 at 2964 fps and the .30-06 at 2987 fps.

What were the average velocities recorded for each caliber?

The .300 Win Mag averaged 3257 fps. The .308 Winchester averaged 2964 fps, and the .30-06 Springfield averaged 2987 fps. These velocities were measured using a Garmin Xero C1 Pro chronograph.

Did the magnum advantage of the .300 Win Mag show in all tests?

Not initially. Against lumber, steel, and sand, all three calibers performed very similarly. The .300 Win Mag's advantage in penetration power only became distinct when facing heavier steel plates.
