The terms "300 AAC Blackout" and "300 Blackout" are often used interchangeably, leading to confusion among firearm enthusiasts. While practically identical in terms of ballistics and functionality, a subtle distinction exists rooted in their origins and nomenclature. This article clarifies the difference and helps you understand why both names are used.
The Origin Story: From AAC to 300 Blackout
The cartridge we know today as the 300 Blackout began its life as the brainchild of Advanced Armament Corporation (AAC), a prominent manufacturer of firearm accessories and suppressors. AAC developed this cartridge, initially marketed as the 300 AAC Blackout, specifically to be used with their suppressors. The "AAC" in the name clearly indicated its origins.
The Transition to 300 Blackout: A Matter of Branding and Adoption
As the cartridge gained popularity and widespread adoption by both civilian and military users, the name gradually simplified. The industry, and subsequently many consumers, began referring to it simply as the 300 Blackout. This transition was a natural progression – a shortening of the original name, highlighting the cartridge's caliber and overall purpose.
Are There Practical Differences? No.
It’s crucial to understand that there is no functional difference between ammunition labeled "300 AAC Blackout" and "300 Blackout." Both cartridges use the same dimensions, projectile weights, and powder charges. They function identically in any firearm chambered for 300 Blackout. The only difference lies in the branding, reflecting the evolution of the cartridge's nomenclature.
Why the Two Names Persist
The persistence of both names is a testament to the cartridge's history. Some manufacturers and enthusiasts continue to use the original "300 AAC Blackout" to acknowledge AAC's pioneering role in its development. Others prefer the shorter, more streamlined "300 Blackout" as it’s become the more common designation.
Choosing Your Ammunition: Focus on Quality, Not Name
When purchasing ammunition, focus on the quality of the manufacturer, the projectile type (e.g., full metal jacket, subsonic, supersonic), and intended application. The difference between "300 AAC Blackout" and "300 Blackout" is purely semantic; both represent the same potent and versatile cartridge.
Conclusion: Semantics Over Substance
In conclusion, while the names differ slightly, the ammunition is essentially the same. Whether you see "300 AAC Blackout" or "300 Blackout," you can be confident that you're dealing with the same high-performing cartridge. Choosing your ammunition should be based on quality, intended use, and the specific features of the round itself, not on the subtle nuance in its name.
