This video tests the penetration depth of .22LR ammunition in water. It demonstrates that CCI Mini Mag hollow points and Winchester Wildcat rounds can penetrate wood at 1 foot deep but fail to penetrate at 15 inches. The test highlights how ammunition type and depth significantly affect penetration capabilities.

Quick Summary

A .22LR bullet's penetration depth in water is significantly limited. In tests, .22LR ammunition penetrated wood at 1 foot deep, but failed to penetrate at 15 inches. Factors like water depth and ammunition type (hollow point vs. round nose) greatly influence how far a bullet will travel and penetrate.

Frequently Asked Questions

How deep can a .22LR bullet penetrate in water?

In this test, .22LR ammunition showed significant variation in water penetration. At a depth of 1 foot, both CCI Mini Mag hollow points and Winchester Wildcat rounds penetrated wood. However, at 15 inches, neither round could penetrate the wood, indicating that even a small increase in depth drastically reduces penetration.

Does hollow point or round nose .22LR ammo penetrate better in water?

The test suggests that for penetrating wood at a depth of 1 foot in water, both CCI Mini Mag hollow points and Winchester Wildcat round nose .22LR performed similarly, creating entry and exit holes. However, the hollow point showed expansion. At greater depths, neither type could penetrate.

What factors affect .22LR penetration in water?

The primary factors affecting .22LR penetration in water, as demonstrated in this test, are the depth of the water and the type of ammunition used (hollow point vs. round nose). The resistance of the target material, in this case wood, also plays a crucial role.

Can a .22LR bullet travel indefinitely in water?

No, a .22LR bullet will not travel indefinitely in water. Its energy is rapidly dissipated by the water's resistance. This test showed that penetration depth is limited, with significant drops in performance occurring with even slight increases in water depth beyond a certain point.
