Frequently Asked Questions

What makes the Gorilla GF-10 in 8.6mm Blackout suitable for suppressed hunting?

The Gorilla GF-10 is ideal for suppressed hunting due to its ability to fire heavy subsonic 8.6mm Blackout projectiles quietly. This setup minimizes noise, potentially allowing shooting without hearing protection, and delivers significant terminal energy despite low velocity.

How does the 8.6mm Blackout cartridge achieve compatibility with standard .308 magazines?

The 8.6mm Blackout cartridge is specifically engineered so its bullet diameter at the case mouth matches the outside diameter of a .308 case. This allows the cartridge to stack correctly within standard .308 PMAGs, ensuring reliable feeding and full magazine capacity.

What is the significance of the 1:3 inch twist rate in the Gorilla GF-10's 8.6mm Blackout barrel?

The 1:3 inch twist rate imparts extreme rotational energy to the heavy 8.6mm Blackout projectiles. This rapid spin stabilizes the bullet effectively and contributes significantly to its terminal ballistics by creating a devastating wound channel through rotational force, not just linear velocity.

What were the results of the ballistics gel test for the Gorilla GF-10's 8.6mm Blackout round?

Testing with Gorilla's 342-grain expander bullet showed impressive results: 100% weight retention and expansion to nearly an inch in diameter. The high rotational energy from the 1:3 twist rate created a substantial permanent cavity, demonstrating devastating performance even at subsonic speeds.
