Description
Built for Shooters Who Demand Maximum Big-Bore Performance
The 600gr Hard Cast LFNGC load occupies a unique position within the 12.7x42mm platform. While lighter than our 700-grain Omega load, it offers a significant increase in velocity while maintaining the heavy-for-caliber characteristics that make the cartridge so effective.
At 1,280 FPS from a 16-inch barrel, this load generates over 2,100 ft-lbs. of energy, delivering substantial impact on steel targets and exceptional momentum compared to conventional AR-15 cartridges.
We’ve paired this bullet with a clean-burning powder from Shooters World that produces consistent ignition, manageable recoil, and reliable cycling in properly tuned AR-15 platforms. While this isn’t a long-range performer, it excels in delivering repeatable accuracy and thumping performance within its effective range. Whether you’re experimenting on steel, testing barriers, or simply running big-bore rounds through your 12.7×42 upper, this load makes itself known.
Loaded in new brass and inspected for quality, Steinel’s 12.7x42mm 600gr Hard Cast ammo is a dependable option for shooters who appreciate big bore performance without the punishing recoil.
LFNGC Bullet Design

- Excellent structural integrity during impact
- Consistent performance across a wide range of velocity
- Reduced bullet deformation
- Improved stability compared to traditional round nose designs
The wide meplat (flat nose) also contributes to impressive energy transfer on target while maintaining dependable feeding characteristics.
