Duration: 11:27

This video details the process of finding an accuracy node for 6.5 Grendel ammunition using H335 powder and 123gr ELD-M bullets from factory seconds. The instructor chronographs various powder charges fired from an 18-inch Bear Creek Arsenal barrel to identify a velocity node, then selects a charge weight for load development and accuracy testing. Initial results indicate the barrel may not be inherently accurate, prompting a discussion about potential future load development with different powders.

Quick Summary

The process of finding an accuracy node for 6.5 Grendel involves chronographing various H335 powder charges with 123gr ELD-M bullets. A velocity node, where muzzle velocity increases minimally across charge weights, is identified for optimal accuracy. Initial tests with an 18-inch Bear Creek Arsenal barrel showed disappointing results, typical for this barrel.

Frequently Asked Questions

What is the process for finding an accuracy node for 6.5 Grendel ammunition?

To find an accuracy node, you chronograph various powder charges with your chosen bullet. Look for a range where muzzle velocity increases minimally across several charge weights. This consistency often correlates with better accuracy. Select a charge within this node for further load development and testing.

What components were used in the 6.5 Grendel accuracy test?

The test utilized an 18-inch Bear Creek Arsenal 6.5 Grendel barrel, H335 powder, and 123-grain ELD-M bullets that were factory seconds from MidwayUSA. The goal was to find an accurate load for this specific rifle configuration.

What were the results of the accuracy testing with the 18-inch Bear Creek Arsenal barrel?

The initial accuracy testing with the developed load yielded disappointing results. The speaker indicated that this performance was typical for this particular 18-inch barrel, suggesting it may not be inherently accurate.

How does the 18-inch Bear Creek Arsenal barrel compare to other barrels?

The speaker noted that their 18-inch Bear Creek Arsenal barrel seems to run slower than expected and performs significantly worse than a 16-inch Parker Hale carbon barrel, which shoots 'lights out' in comparison.
