6.5 Grendel vs 6.5 Creedmoor: Similar on Steel?

Published on November 27, 2022
Duration: 4:56

This video compares the steel penetration capabilities of the 6.5 Grendel and 6.5 Creedmoor calibers using the same 120-grain ELD bullet. The test involved shooting at mild steel plates ranging from 1/4 inch to 1 inch thick. While both calibers are chambered in rifles with 20-inch Ballistic Advantage barrels, the 6.5 Creedmoor demonstrated superior penetration due to its larger case capacity and higher velocity.

Quick Summary

The 6.5 Creedmoor demonstrates superior steel penetration compared to the 6.5 Grendel, primarily due to its larger case capacity leading to higher velocities. In tests with 120-grain ELD bullets and 20-inch barrels, neither caliber penetrated 3/8 inch steel, but the Creedmoor achieved significantly deeper penetration (0.281" vs 0.17").

Frequently Asked Questions

What is the difference in case capacity between 6.5 Grendel and 6.5 Creedmoor?

The 6.5 Creedmoor has a larger case capacity than the 6.5 Grendel. This greater capacity allows it to hold more gunpowder, which directly contributes to higher muzzle velocities when fired.

Did the 6.5 Grendel or 6.5 Creedmoor penetrate 3/8 inch steel plate?

Neither the 6.5 Grendel nor the 6.5 Creedmoor, when fired with a 120-grain ELD bullet from a 20-inch barrel, were able to penetrate a 3/8 inch (0.375 inch) mild steel plate in this test.

How much deeper did the 6.5 Creedmoor penetrate than the 6.5 Grendel?

In the test on 3/8 inch steel, the 6.5 Creedmoor penetrated 0.281 inches, while the 6.5 Grendel penetrated 0.17 inches. This means the Creedmoor achieved over 0.100 inches more penetration.

What factors influence the steel penetration of 6.5 Grendel and 6.5 Creedmoor?

Key factors include the cartridge's case capacity (affecting velocity), bullet weight and construction (like jacket and lead composition), and barrel length. Higher velocity and more robust bullet construction generally lead to deeper penetration.
