6.5 Grendel VS 50 Beowulf | The Grendel Matches Big Bore At 100 Yards

Published on February 7, 2026
Duration: 5:12

This video provides a detailed 100-yard ballistics comparison between the 6.5 Grendel and 50 Beowulf cartridges, utilizing a LabRadar for precise velocity and energy measurements. The analysis, conducted by an instructor with high authority, highlights the 6.5 Grendel's superior aerodynamic efficiency, showing it nearly matches the 50 Beowulf in kinetic energy at 100 yards despite a significant muzzle velocity difference, suggesting potential for greater energy retention at longer distances with less recoil.

Quick Summary

At 100 yards, the 6.5 Grendel (1343 ft-lbs) nearly matches the 50 Beowulf (1366 ft-lbs) in kinetic energy, despite the 50 Beowulf's higher muzzle energy. This demonstrates the 6.5 Grendel's superior aerodynamic efficiency, suggesting it may retain more energy at longer distances with less recoil.

Frequently Asked Questions

How does the 6.5 Grendel compare to the 50 Beowulf in kinetic energy at 100 yards?

At 100 yards, the 6.5 Grendel with a 120-grain CX bullet delivers approximately 1343 ft-lbs of kinetic energy, while the 50 Beowulf with a 300-grain FTX bullet provides about 1366 ft-lbs. This shows the 6.5 Grendel nearly matches the 50 Beowulf in energy at this distance.

What are the muzzle velocities for the 6.5 Grendel and 50 Beowulf in this test?

The 6.5 Grendel achieved a muzzle velocity of 2423 fps with its 120-grain load. The 50 Beowulf recorded a muzzle velocity of 1848 fps with its 300-grain load. Both rifles used 16-inch barrels for the comparison.

Which cartridge retains more energy at 100 yards, 6.5 Grendel or 50 Beowulf?

While the 50 Beowulf starts with significantly more energy, the 6.5 Grendel demonstrates superior aerodynamic efficiency. At 100 yards, their kinetic energies are nearly identical, suggesting the 6.5 Grendel may retain more energy beyond this distance and offers lower recoil.

What equipment was used to measure ballistics in the 6.5 Grendel vs 50 Beowulf comparison?

A LabRadar ballistic velocity radar was used to precisely measure the muzzle velocity and velocity at 50 and 100 yards for both the 6.5 Grendel and 50 Beowulf cartridges. This ensured accurate data collection for the comparison.
