Frequently Asked Questions

What are the key terminal ballistics of the Speer 75gr Gold Dot in 5.56mm NATO?

The Speer 75gr Gold Dot shows impressive performance. From an 11.5" SBR, it achieved 2,370 FPS, 19.5" penetration, and retained 73.0 GR with significant expansion. A 20" rifle yielded 2,774 FPS, 15.2" penetration, and retained 66.2 GR with greater expansion.

How does the Speer 75gr Gold Dot perform through barriers like a windshield?

In a windshield test from an 11.5" SBR at 2,328 FPS, the 75gr Gold Dot penetrated approximately 22 inches, retained 60.9 GR, and expanded to 0.426", demonstrating effective barrier performance for defensive scenarios.

What is a critical consideration for using Speer 75gr Gold Dot ammunition?

A crucial factor is ensuring your rifle's twist rate can adequately stabilize the heavy 75-grain bullet. Faster twist rates, such as 1:7 or 1:8 inches, are generally recommended for optimal accuracy and performance with this ammunition.

What makes the Speer 75gr Gold Dot unusual compared to other 5.56mm rounds?

The 75gr weight is heavier than many common 5.56mm rounds, which typically range from 62-65 grains. It also utilizes a bonded soft point design, differing from more common Open Tip Match (OTM) configurations.
