Your source for the best ammunition made in Lone Star State

For more than 15 years, Parabellum Research (PBR) has manufactured premium small arms ammunition in Central Texas. As a family-owned and operated company, we’ve earned the trust of shooters, firearms professionals, law enforcement agencies, commercial ranges, and contract customers across the Lone Star State by delivering dependable performance, consistent quality, and exceptional value.

Unlike many high-volume manufacturers focused solely on output, PBR prioritizes consistency, reliability, and real-world performance for shooters who demand more from their ammunition. We build ammunition the right way — using premium components, commercial-grade processing and loading equipment, and rigorous inspection standards at every stage of production. The result is clean, accurate, and reliable ammunition trusted for everything from casual range use to demanding professional applications.

Perfect Practice Ammunition™ was designed to deliver what most bulk-range ammunition does not; reliable ignition, consistent velocities, clean burning powders, and repeatable accuracy at an affordable price. Available in both our Premium Line using new-brass and the Value Line using professionally processed brass, PBR ammunition offers dependable training performance without sacrificing quality.

Over the years, we have produced ammunition in numerous calibers and configurations for applications including:

• Recreational and high-volume range training
• Hunting and varmint control
• Cowboy Action
• Supressor optimized subsonic
• USPSA, IPSC, and 3-Gun competition
• Lead-free frangible training
• Precision long-range shooting
• Firearm testing and evaluation
• Law enforcement and defensive training
• Custom load development for rare or specialized firearms

In addition to manufacturing our own ammunition, PBR provides contract loading and production support services for companies seeking scalable, professional ammunition manufacturing without the overhead of building an in-house operation. From brass processing and priming to loading, sealing, and inspection, we provide the equipment, experience, and production capacity needed to help bring ammunition products to market efficiently and reliably.

We’re still family owned, still Texas made, and still committed to producing ammunition shooters can trust every time they pull the trigger.
