This video from Demolition Ranch features an expert-level demonstration of lumber penetration using a .308 Winchester round fired from an Armalite AR-10 equipped with a Primary Arms 1-8x24 scope. The test highlights the significant penetration capabilities of the .308, even through multiple layers of wood, and explores factors affecting bullet performance like board spacing. The instructor provides clear explanations of optic features like Front Focal Plane reticles.

Quick Summary

A .308 Winchester round exhibits substantial penetration through wood, capable of passing through multiple 2-inch boards and 4x4 posts. Factors like board spacing significantly influence bullet stability and the depth of penetration, with spaced boards causing faster tumbling and reduced effectiveness.

Frequently Asked Questions

How does a .308 Winchester round perform against wood?

In a Demolition Ranch test, a .308 Winchester round demonstrated significant penetration through multiple stacked 2-inch boards and 4x4 posts. The bullet's performance was influenced by factors like board spacing, which affected its stability and tumbling.

What is a Front Focal Plane (FFP) optic and why is it useful?

A Front Focal Plane (FFP) optic features a reticle that scales with magnification. This means holdover points remain proportionally accurate at all zoom levels, making it easier to make precise shots at varying distances without recalculating.

What is the difference between .308 Winchester and .300 Winchester Magnum ballistics?

.300 Winchester Magnum cartridges are generally faster and more powerful than .308 Winchester. The .300 Win Mag travels about 500 fps faster and carries 50% more energy, even with bullets of similar weight.
