When performance in close quarters matters most, SIG SAUER delivers. Our 120-grain Solid Copper .300 Blackout cartridge is purpose-built for short barrel rifles, maximizing terminal effect and reliability where every inch—and every shot—counts.
- Annealed Copper Tip- Advanced thermal treatment enhances expansion upon impact, delivering devastating terminal performance and consistent energy transfer.
- Optimized for SBRs- Tuned powder charge and projectile design ensure full powder burn and velocity efficiency in barrels as short as 7 inches.
- Barrier Blind Performance- Solid copper construction retains weight through glass, drywall, and light auto sheet metal, making it ideal for tactical and defensive use.
- Lead-Free Projectile- Meets environmental and training requirements without sacrificing performance.
From the breach to the barrel’s edge, this is the .300 BLK redefined.
