  • Why the 352gr or the 350gr?

We developed the 352gr Maker REX to address specific feeding challenges in semi-automatic 8.6 Blackout rifles. Key improvements include:

  • Pointed tip design - Dramatically improved feeding reliability in gas-operated rifles
  • Better ballistic coefficient - .61 G1 BC (nearly 10% increase over 350gr's .53 BC)

Terminal Performance - Proven on Dangerous Game

The 352gr Maker REX has been successfully used to harvest:

  • Cape Buffalo in Africa - Proven dangerous game performance
  • Whitetail deer, elk, wild hogs, and black bear across North America
  • Exotic game including kudu and nilgai

The Maker REX bullet is precision CNC-machined from solid copper with engineered expansion channels. Upon impact, the REX projectile expands to nearly three times its original diameter (.338" to approximately 2.0") while maintaining nearly 100% weight retention. This combination delivers maximum energy transfer and deep penetration.

Best Applications

Perfect For:

  • Semi-automatic 8.6 Blackout rifles
  • Bolt-action platforms requiring maximum terminal performance
  • Suppressed hunting (whitetail, elk, hogs, black bear)
  • Dangerous game hunting where deep penetration is critical
  • Situations requiring both reliability and stopping power

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

Frequently Asked Questions

Q: What's the main advantage over the 350gr?
A: The pointed tip design dramatically improves feeding reliability in semi-automatic rifles, and the higher BC (.61 vs .53)

Q: Is this suitable for dangerous game?
A: Yes. The 352gr has been proven on Cape Buffalo and other dangerous game. The deep penetration and massive expansion make it suitable for large, tough animals.

Q: Can I use this for whitetail deer?
A: Absolutely. While it's capable of dangerous game, it performs excellently on whitetail, delivering one-shot stops with minimal meat damage despite the massive wound channel.
