Published on December 21, 2018
Duration: 19:47

This video details the reloading process for 6.5 Grendel cartridges using 107gr Sierra Match King bullets. It explores two powder choices: Alliant Power Pro Varmint and Alliant Power Pro 2000-MR, presenting load data, seating procedures, and live-fire results with chronograph readings and group sizes. The instructor, Johnny, provides insights into the performance of lighter bullets in the Grendel platform and discusses potential powder suitability.

Quick Summary

The 107gr Sierra Match King is a lighter bullet option for the 6.5 Grendel, offering potential for high velocity and accuracy. Alliant Power Pro Varmint proved effective, yielding velocities around 2500-2570 fps and good groups. Alliant Power Pro 2000-MR was less suitable for this bullet weight and an 18-inch barrel, producing lower velocities and less consistent results.

Frequently Asked Questions

What are the recommended powders for reloading 6.5 Grendel with 107gr Sierra Match King bullets?

The presenter found Alliant Power Pro Varmint to be a suitable powder, achieving good accuracy and velocities around 2500-2570 fps. Alliant Power Pro 2000-MR was less effective for this bullet weight and barrel length, yielding lower velocities and less consistent groups.

What is the optimal overall cartridge length (OAL) for 6.5 Grendel with 107gr Sierra Match King bullets in this setup?

An overall cartridge length of 2.280 inches was used to ensure magazine compatibility. This resulted in approximately 0.085 inches of bullet jump to the rifling in the 18-inch Faxon barrel.

What were the key findings from testing Alliant Power Pro 2000-MR with 107gr Sierra Match King bullets in 6.5 Grendel?

Testing indicated that Power Pro 2000-MR is likely too slow for this bullet weight in an 18-inch barrel, resulting in lower velocities and less impressive accuracy compared to Power Pro Varmint. While brass showed no pressure signs, the performance was not optimal.

What are the benefits of using lighter bullets like the 107gr Sierra Match King in a 6.5 Grendel?

Lighter bullets in the 6.5 Grendel can potentially achieve higher velocities, which may translate to better accuracy and flatter trajectories. The presenter found the 107gr Match King to be a promising option for his specific rifle.
