Our ammunition casings are inspected using optical lasers to verify wall thickness and primer pocket alignment. This ensures that every round cycles smoothly through high-capacity magazines without jams or extractor failures.
We load our cartridges using primers that are sensitive enough for light firing pin strikes but highly resistant to accidental drops. This guarantees absolute reliability in defensive situations when you need it most.
The bullet jackets are engineered to engage the rifling lands perfectly, reducing barrel wear and maximizing muzzle velocity. This results in flatter trajectories and tighter groupings at long distance shooting ranges.
Every batch of ammo undergoes temperature testing to verify velocities in freezing conditions and extreme summer heat. We are committed to supplying ammunition you can trust in any environmental condition.
Our powders are formulated to burn completely within the barrel, minimizing muzzle flash and keeping your position hidden in low-light environments. This is a critical feature for tactical teams and night operations.
We utilize low-friction coatings on the projectiles to reduce copper fouling inside the bore. This keeps your rifling clean for longer periods and decreases the amount of solvent needed during cleaning.
Each box of ammunition is sealed in heavy-duty cardboard with moisture-absorbent packets to ensure a long shelf life. Keep your stockpile in a cool, dry place for maximum longevity and reliability.
Our projectiles are weight-sorted to a tolerance of plus or minus one-tenth of a grain. This extreme consistency is what allows precision marksmen to achieve repeatable accuracy at distance.
We match our bullet designs to standard twist rates, ensuring optimal stabilization in flight. This prevents bullet tumbling and keyholing, delivering clean round holes on paper targets every time.
The nickel-plated brass cases offer superior corrosion resistance compared to standard brass, making them ideal for duty carry in humid environments or coastal patrol applications.
We provide full ballistics charts and drop data for all of our loads on our website, allowing you to dial in your optics before heading out to the range.
Our ammunition utilizes flash-suppressed propellants that keep your night vision gear from blooming during low-light training drills. This makes it the ideal choice for tactical law enforcement teams conducting night searches and defensive actions.
Safety Warnings and Ammo Disclaimer
Ammunition is dangerous if mishandled. Use only in firearms in good condition chambered for this exact caliber. Discharge in poorly ventilated areas may result in lead exposure. For shipping restrictions, state compliance, and SDS sheets, visit our official page for more information.
