Frontier Cartridge FR400 Military Grade 300 Blackout 125 gr FMJ Ammunition: Precision, Reliability, and Performance

For serious shooters, competitive marksmen, and small game hunters, finding ammunition that consistently delivers precision and reliability is paramount. The Frontier Cartridge FR400 Military Grade Centerfire Rifle ammunition, specifically chambered in .300 Blackout with a 125-grain Full Metal Jacket (FMJ) bullet, stands out as a top-tier choice designed to meet rigorous demands. Manufactured in the USA, this ammunition offers a blend of performance characteristics typically associated with military-grade standards, making it an excellent option for a diverse range of applications, from intensive range sessions to responsible varmint management.

Why Choose Frontier Cartridge FR400 for Your .300 Blackout Rifle?

When you’re considering ammunition for your .300 Blackout platform, whether it’s an AR-15 pistol, an SBR, or a full-size rifle, several factors come into play: consistent feeding, reliable ignition, accurate bullet flight, and appropriate terminal performance for your intended use. The Frontier Cartridge FR400 is engineered to excel in these critical areas, providing peace of mind and enhanced shooting experiences.

Target Shooters and Range Enthusiasts: Are you looking for dependable ammunition for practice, plinking, or maintaining your marksmanship skills? The FR400’s 125-grain FMJ bullet is ideal for high-volume shooting. Its consistent muzzle velocity of 2175 feet per second (fps) translates into predictable trajectories, helping you achieve tighter groups on paper or steel targets. The Full Metal Jacket design ensures reliable feeding in a wide array of firearms, reducing the likelihood of malfunctions that can interrupt training or competitive sessions. Furthermore, the brass cartridge cases are a significant advantage for those who reload their ammunition, offering durability for multiple reloads and maximizing your investment.

Small Game and Varmint Hunters: Is this ammunition suitable for hunting small game or varmints? With a muzzle energy of 1313 foot-pounds (ft-lbs), the 125 gr FMJ bullet delivers sufficient energy for ethical dispatch of small to medium-sized varmints. While FMJ bullets are generally not designed for maximum expansion, their deep penetration can be effective for precise shot placement on smaller animals. It's crucial for hunters to understand local regulations regarding bullet types for hunting, but for species where FMJ is permitted and effective, the FR400 provides a reliable and accurate solution. Its consistent performance means you can trust your shot when it counts most in the field.

What Does "Military Grade" Mean for Your Ammunition?

The term "military grade" isn't just a marketing slogan; it signifies a commitment to stringent manufacturing standards and quality control processes. For Frontier Cartridge, it means:

• Exceptional Reliability: Each round is manufactured to precise specifications to ensure consistent ignition and reliable feeding, even under less-than-ideal conditions. This is crucial for both defensive training and field applications where a malfunction can have serious consequences.
• Durable Components: The use of high-quality brass for cartridge cases and military-grade boxer primers contributes to the overall robustness of each round. Boxer primers are highly desirable for their reliability and ease of reloading, a significant benefit for ammunition enthusiasts.
• Consistent Performance: From one box to the next, you can expect uniform ballistic performance. This consistency is vital for maintaining accuracy, especially when shooting at varying distances or under different environmental conditions. It allows shooters to accurately predict bullet drop and wind drift, enhancing their ability to make precise shots.

Understanding the .300 Blackout Caliber

The .300 Blackout (300 BLK) has rapidly gained popularity due to its versatility and performance in short-barreled rifles and suppressed firearms. It was designed to offer .30 caliber performance from an AR-15 platform with minimal changes to the firearm itself, often requiring just a barrel swap. This caliber is unique because it performs exceptionally well in both supersonic (like the 125 gr FR400) and subsonic configurations, offering a wide range of applications.

• Supersonic Performance: The Frontier Cartridge FR400 125 gr FMJ is a supersonic load, meaning the bullet travels faster than the speed of sound. This makes it ideal for maximizing effective range and delivering full energy at impact for targets at a distance or for the hunting of small game. The 2175 fps muzzle velocity is impressive for the .300 Blackout, ensuring a flat trajectory over common shooting distances.
• Compatibility: Designed specifically for modern sporting rifles, including popular AR-15 variations, the FR400 ensures seamless compatibility and reliable cycling, making it a go-to choice for training and general use.

Key Features and Benefits of Frontier Cartridge FR400

Let's delve deeper into the specific attributes that make this ammunition a standout choice:

• Full Metal Jacket (FMJ) Bullet: The 125-grain FMJ bullet is characterized by its lead core encased in a copper jacket. This design minimizes lead fouling in your barrel, promoting cleaner operation and easier maintenance. FMJ bullets are renowned for their excellent penetration capabilities and consistent flight characteristics, making them perfect for target shooting and situations where over-penetration is not a primary concern. They are also generally more affordable, allowing for more extensive practice sessions without breaking the bank.
• Brass Casing Material: The use of brass casings is a hallmark of quality ammunition. Brass is durable, resists corrosion, and, most importantly, is highly suitable for reloading. For shooters who save their spent casings, the Frontier Cartridge FR400 offers significant value, extending the life of your ammunition investment through personal reloading. This also speaks to the brand’s commitment to providing a premium product.
• American Made Quality: Produced entirely in the United States, Frontier Cartridge ammunition adheres to rigorous domestic manufacturing standards. This commitment to American craftsmanship ensures a high level of quality control, supporting domestic industry, and delivering a product that shooters can trust for its consistency and performance.
• Optimized Packaging: Each box contains 20 rounds, and cases come with 10 boxes, totaling 200 rounds. This bulk packaging is convenient for storage, transport, and ensures you have an ample supply for extended range sessions or hunting trips without constant restocking. This configuration also makes it easier for retailers like DEGuns to offer this product efficiently to consumers.

How Does Frontier Cartridge Ammunition Enhance Your Shooting Experience?

Choosing the right ammunition can profoundly impact your shooting accuracy, the longevity of your firearm, and your overall enjoyment.

• Improved Accuracy: The consistent manufacturing processes behind Frontier Cartridge FR400 result in uniform bullet weight, consistent powder charges, and precisely seated primers. This translates directly to improved accuracy downrange, allowing you to tighten your groups and become a more proficient shooter.
• Enhanced Firearm Reliability: Ammunition that is manufactured to tight tolerances ensures smooth feeding, extraction, and ejection, minimizing the risk of costly and frustrating malfunctions. This is particularly important for semi-automatic firearms like the AR-15, which rely on consistent ammunition dimensions for reliable cycling.
• Cost-Effectiveness for Practice: While offering "military-grade" performance, the 125 gr FMJ load is also a practical choice for everyday training. Its robust construction means it performs reliably without the premium cost often associated with specialized hunting or match-grade ammunition. This balance of quality and affordability allows shooters to hone their skills without excessive financial burden.
• Versatility: Whether you're zeroing in a new optic, participating in a casual shooting competition, or preparing for small game season, the Frontier Cartridge FR400 provides the versatility needed to cover various scenarios with a single, dependable ammunition type.
