Bullet Technology – Maker T-REX (Tipped Rapid EXpanding)

At the core of this round is the Maker Bullets 150gr T-REX, a precision CNC-machined, solid copper, lead-free projectile purpose-built for the .300 AAC Blackout cartridge.

Key design features include:

• Polymer tip to improve ballistic coefficient and initiate expansion

• Monolithic copper construction for structural integrity

• Aggressive expansion up to nearly 3× original diameter

• Near-100% weight retention for deep, straight-line penetration

Unlike traditional jacketed bullets, the T-REX expands reliably without fragmenting, allowing it to drive through bone and dense tissue while creating large wound channels and consistent terminal results.

Performance Characteristics:

Expansion & Penetration

The polymer tip initiates rapid expansion upon impact, forming a large mushroom while the solid copper body maintains nearly full mass. This results in excellent penetration with dramatic terminal effect, making it highly effective for hunting and defensive roles.

Accuracy

The Maker 150gr T-REX is designed specifically for .300 Blackout and is widely reported to deliver MOA-capable accuracy in properly configured rifles, even from short barrels.

Terminal Performance

Field reports indicate reliable pass-throughs on medium game, with consistent expansion and energy transfer at typical .300 BLK hunting distances.

---

Ideal Applications:

• Hunting: Deer, hogs, and similar game (where legal)

• Short-barrel rifles & pistols

• Suppressed or unsuppressed platforms

• Tactical and defensive use

• Shooters requiring expansion at lower velocities
