308 Winchester, 168 Gr Maker T-REX – 20 Rounds

.308 Winchester 168gr Maker T-REX – Supersonic Precision Hunting Ammunition

The Just Cause Solutions .308 Winchester 168gr Maker T-REX pairs the proven reach of the .308 Winchester cartridge with the terminal performance of Maker's Tipped Rapid EXpanding solid copper projectile. At 2,650fps from a 24" barrel, this load delivers a flat trajectory and hard-hitting expansion on medium to large game, making it a versatile choice for hunters and precision shooters alike. Whether you're taking shots across an open field or pushing the capability of your suppressed .308 bolt gun, the T-REX delivers consistent performance when it counts.

All of our ammunition is pressure tested using a PCB PIEZOTRONICS Conformal Transducer according to Voluntary Industry Performance Standard as set forth by SAAMI.

The Maker T-REX Advantage

The T-REX builds on Maker's proven REX expanding copper platform by adding a polymer tip for improved ballistic coefficient and more consistent long-range performance. Key features include:

• Polymer tip – Increases BC for a flatter trajectory and improved wind resistance at distance
• Reliable expansion – Engineered to expand consistently across a wide velocity range
• Nearly 100% weight retention – Solid copper construction maintains mass for deep penetration
• CNC-machined precision – Every projectile is machined to exact tolerances for consistent performance
• Lead-free construction – Compliant with lead-free hunting regulations where applicable

Hunting Application

The .308 Winchester remains one of the most widely used hunting cartridges in North America, and the 168gr T-REX takes full advantage of its flat-shooting, hard-hitting nature. With excellent sectional density and a high BC for the platform, this load is well-suited for whitetail deer, mule deer, hogs, black bear, and similarly sized game at appropriate ranges. The T-REX's expanding copper construction delivers a wide wound channel with deep penetration — without the lead core separation concerns of traditional bonded bullets.

It is the hunter's responsibility to adequately test their rifle system at distance prior to hunting wild game!

Frequently Asked Questions

Q: What game is this load appropriate for?
A: The 168gr T-REX in .308 Winchester is well-suited for medium to large game including whitetail deer, mule deer, hogs, and black bear at appropriate ranges. Shot placement and distance remain the hunter's responsibility.

Q: What makes the T-REX different from the standard REX?
A: The T-REX adds a polymer tip to Maker's proven REX design. This improves the ballistic coefficient for a flatter trajectory and more consistent expansion initiation on impact, particularly at longer ranges where velocity has decreased.

Q: Can I use this in a suppressed .308?
A: Yes. This supersonic load pairs well with a suppressor to reduce muzzle blast. Keep in mind a supersonic crack will still be present downrange. For a fully suppressed, hearing-safe experience, a subsonic load would be required.

Q: What twist rate does my barrel need?
A: A 1:12 or faster twist rate is required to properly stabilize the 168gr T-REX. Most modern .308 Winchester rifles are manufactured with twist rates between 1:10 and 1:12, making them well-suited for this load.

Q: How is Just Cause USA's ammunition tested?
A: Every batch we produce is pressure tested using our own PCB PIERZOTRONICS Conformal Transducer according to Voluntary Industry Performance Standard as set forth by SAAMI. This level of in-house testing is uncommon in the industry and reflects our commitment to safety and consistency in every round we release.
