This video details the reloading and range testing of the 130gr Sierra GameChanger bullet in 6.5 Creedmoor, utilizing Alliant Reloader 16 powder. Accuracy results from both a T/C Compass bolt-action and an Aero Precision AR-10 were mixed, with the GameChanger showing significant expansion but notable weight loss in ballistic gel. While Reloader 16 provided excellent velocity consistency, the bullet's performance did not meet expectations for accuracy or weight retention in this specific test.

Quick Summary

The 130gr Sierra GameChanger in 6.5 Creedmoor yielded mediocre accuracy (over 1 MOA) and significant weight loss (retaining 67.5-87.2gr) after expansion in ballistic gel. Alliant Reloader 16 powder provided excellent velocity consistency, but overall performance was mixed.

Frequently Asked Questions

What were the key findings from testing the 130gr Sierra GameChanger in 6.5 Creedmoor?

The 130gr Sierra GameChanger in 6.5 Creedmoor showed mediocre accuracy (over 1 MOA) and significant weight loss (retaining 67.5-87.2gr) after expansion in ballistic gel. Alliant Reloader 16 powder provided excellent velocity consistency, but overall performance was mixed.

How did the 130gr Sierra GameChanger perform in ballistic gel tests?

The 130gr Sierra GameChanger expanded violently in ballistic gel, but it lost a substantial amount of weight, retaining only between 67.5gr and 87.2gr. This indicates significant fragmentation, unlike bonded bullets.

What role did OAL play in the reloading process for the 6.5 Creedmoor test?

Overall Length (OAL) was critical, especially for the AR-10 platform, which was limited to 2.810" for magazine compatibility. This shorter OAL resulted in a different bullet jump compared to the T/C Compass, which allowed for a longer 2.950" OAL.

Which brass types were used, and what differences were noted?

Peterson Small Rifle Primer (SRP) brass was used for the bolt gun, and Starline SRP brass for the AR-10. Peterson brass has a smaller .060" flash hole and slightly less internal capacity, leading to more compressed loads at higher charge weights.
