Frequently Asked Questions

What are the key components for reloading 130gr Sierra GameChanger bullets in 6.5 Creedmoor?

This process involves 130gr Sierra GameChanger bullets, Alliant Reloader 16 powder, CCI No. 41 primers, and either Peterson or Starline 6.5 Creedmoor brass. Reloading tools like a press and dies are also essential.

How does Peterson brass differ from Starline brass for 6.5 Creedmoor reloading?

Peterson 6.5 Creedmoor brass features a smaller .060" flash hole, requiring a specific decapping pin. It also has slightly less internal capacity than Starline brass, which can lead to more compressed powder loads at maximum charge weights.

What are the recommended Overall Length (OAL) settings for 6.5 Creedmoor in a T/C Compass and an AR-10?

For a T/C Compass bolt action, a longer OAL of 2.950" is possible. For an AR-10 using Magpul magazines, the OAL is limited to 2.810" to ensure reliable feeding.

What were the terminal ballistics results for the 130gr Sierra GameChanger in 6.5 Creedmoor?

In ballistic gel, the 130gr Sierra GameChanger expanded significantly but lost substantial weight, retaining only 67.5gr to 87.2gr, indicating less robust construction compared to bonded bullets.
