8.6 Blackout 300gr Makers Extreme Expanding, 20ct

Description

Acri Ammunition 8.6 Blackout – 300gr Extreme Expanding (Maker REX)

The Acri Ammunition 8.6 Blackout 300 Grain Extreme Expanding load featuring the Maker Bullets REX (Rapid EXpanding) projectile is a purpose-built subsonic hunting cartridge designed for maximum terminal performance in suppressed platforms. Engineered specifically for the unique characteristics of the 8.6 Blackout cartridge, this load delivers exceptional expansion, deep penetration, and outstanding sound suppression.

Built around a 300gr solid copper Maker REX bullet, this ammunition is optimized for AR-10 and bolt-action rifles equipped with the required fast twist barrels, most commonly 1:3 twist, which is essential for stabilizing heavy subsonic projectiles and enhancing terminal effectiveness through rotational energy.

Bullet Technology – Maker REX Extreme Expanding

The Maker REX is a CNC-machined, solid copper, lead-free expanding projectile engineered to expand reliably at subsonic velocities. Unlike traditional subsonic bullets that depend on yaw or fragmentation, the REX is designed to open into multiple petals, creating large wound channels while retaining nearly 100% of its original weight.

This combination results in:

• Reliable expansion at low velocities

• Straight-line penetration through hide, muscle, and bone

• Excellent weight retention and structural integrity

• Consistent terminal performance on medium-sized game
