Product Details

The Sig Sauer Max Expansion 300 Blackout 194 Gr Subsonic ammunition delivers exceptional terminal performance through advanced Lehigh Defense Maximum Expansion technology. Featuring a 194-grain solid monolithic copper bullet with cavernous hollow point design, this subsonic load achieves optimal expansion and wound channel creation while maintaining suppressor-friendly velocities.

  • Sig Sauer Max Expansion 300 Blackout 194 Gr Subsonic ammunition
  • 20 rounds per box
  • Lehigh Defense Maximum Expansion BTHP bullets
  • Subsonic velocity (approximately 1,000-1,050 fps)
  • Premium brass cases with Boxer primers
  • Suppressor optimized performance

The Maximum Expansion technology creates razor-sharp petals that expand to an average diameter of 1.203 inches upon contact with fluid-based mediums, while penetrating an average of 15.6 inches in ballistic gelatin. Ideal for hunting, self-defense, and tactical applications, this ammunition functions reliably in AR-15 platforms and standard 5.56/.223 magazines while delivering superior terminal ballistics in suppressed firearms.
