6.5 Creedmoor, 130 Gr Maker T-Rex (Tipped Rapid EXpanding) – 20 Rounds

6.5 Creedmoor 130gr Maker T-REX – High-BC Supersonic Hunting Ammunition

The Just Cause Solutions 6.5 Creedmoor 130gr Maker T-REX combines the flat-shooting characteristics of the 6.5 Creedmoor with the terminal performance of Maker's Tipped Rapid EXpanding solid copper projectile. With an impressive .550 G1 ballistic coefficient, this load retains velocity exceptionally well at distance, making it one of the most capable hunting loads we offer for medium to large game. Whether you're running a bolt gun from a blind or reaching out across an open field, the T-REX delivers the accuracy and terminal performance you need for a clean, ethical harvest.

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 6.5 Creedmoor has earned its reputation as one of the most versatile hunting cartridges available, and the 130gr T-REX takes full advantage of that platform. The .550 G1 BC means this load bucks wind and retains energy exceptionally well at extended ranges, making it well-suited for whitetail, mule deer, pronghorn, hogs, and similarly sized game. 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 130gr T-REX in 6.5 Creedmoor is well-suited for medium to large game including whitetail deer, mule deer, pronghorn, 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: Is the 6.5 Creedmoor a good suppressor cartridge?
A: Yes. While this is a supersonic load, the 6.5 Creedmoor is widely used with suppressors. The suppressor reduces the muzzle blast significantly, though a supersonic crack will still be present downrange.

Q: What twist rate does my barrel need?
A: A 1:9 or faster twist rate is recommended to properly stabilize the 130gr T-REX projectile. Most modern 6.5 Creedmoor rifles ship with 1:8 twist barrels, which is ideal for this load.

Q: How is Just Cause USA's ammunition tested?
A: Every batch we produce is pressure tested using our own PCB PIEZOTRONICS 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.
