🔹 Reinforced Primer Cup

• Heavy brass cup engineered to withstand high bolt forces and extreme chamber pressure (over 50,000–60,000 PSI typical in .50 BMG loads)

• Very hot ignition flame to ensure consistent burn of massive powder charges, often up to 240 grains or more of slow-burning powders like H50BMG or WC860

🔹 Thick-Walled Primer Body

• Reduces risk of slam-fire, primer flow, or deformation in heavy bolt-action rifles and semi-automatic .50 BMG platforms
