Custom 7PRC Hunting Rifle - Different Powders Tested

Published on November 23, 2024
Duration: 10:09

This video details the process of zeroing a custom 7 PRC hunting rifle and testing various handloads against factory ammunition. The instructor demonstrates load development with different powders (H1000 and Ramshot LRT) and bullet seating depths, followed by live-fire testing at 100 and 600 yards. The focus is on achieving optimal velocity and accuracy for hunting applications, with practical advice on windage adjustments for long-range shots.

Quick Summary

The custom 7 PRC hunting rifle features a 25-inch barrel, Terminus Zeus action, Grybow stock, and Maven RS optic. Load development tested H1000 and Ramshot LRT powders, with H1000 yielding approximately 2850 ft/s. The presenter considers 650 yards an ethical hunting distance for this cartridge.

Frequently Asked Questions

What are the key components of the custom 7 PRC hunting rifle featured in the video?

The custom 7 PRC rifle is built on a Terminus Zeus long action, features a Grybow stock, an MDT Sky Pod bipod, and a Maven RS optic. It is equipped with a 25-inch barrel and a Cora tuner brake for recoil reduction.

What powders were tested for the 7 PRC handloads, and what were the results?

The video tested Hodgdon H1000 and Ramshot LRT powders. With H1000 (67.4 grains), velocities around 2850 ft/s were achieved. Ramshot LRT at 70 grains yielded lower velocities (2614 ft/s), suggesting it may require higher charges or be less suitable for high-velocity loads in this configuration.

How does bullet jump affect 7 PRC handloads?

The presenter tested handloads with a bullet jump of 0.040 inches, compared to the factory load's 0.020-inch jump. This increased jump was part of the handload development to see its effect on consistency and performance, though it requires careful testing to optimize.

What are the recommended velocities and ethical hunting distances for a 7 PRC?

For hunting applications with a 7 PRC, velocities between 2850 and 2900 ft/s are considered desirable. The presenter considers 650 yards to be an ethical maximum hunting distance for this cartridge.
