Byrna® Kinetic Less-Lethal 12-Gauge Shotgun Ammunition – .61 Caliber Fin-Tailed Projectile – 2.5" Primer-Actuated Shotshell – 20 Joules Kinetic Impact – 10-Round Box – SS61301
Product Description
The Byrna® Kinetic Less-Lethal 12-Gauge Shotgun Ammunition (SS61301) represents a monumental, paradigm-shifting technological breakthrough in personal asset defense, home protection logistics, and low-consequence intervention tactics, masterfully engineered in the USA to deliver absolute stopping power without resorting to lethal force. Representing the most radical advancement in civilian shotshell engineering in over three decades, this state-of-the-art defensive tool seamlessly bridges the massive operational divide between standard non-lethal aerosol sprays and traditional lethal firearms. While legacy defensive options require specialized compressed-gas launchers or platform-specific mechanical frames, this innovative array operates natively inside the 12-gauge shotgun you already own. This high-efficiency ammunition package (810042113350) establishes an indispensable primary security asset to manage perimeter threat profiles, safeguard close-quarter residential boundaries, and optimize intermediate tactical staging lines.
The foundational performance triumph of this innovative Less-Lethal shotshell relies on its proprietary, aerodynamically superior .61 caliber fin-tailed polymer projectile nested inside a 2.5-inch protective sabot shell. Upon firing, a custom-designed clamshell sabot and internal wad separation loop ensure absolute, concentric bore-line alignment while clearing the muzzle exit. Once free of the barrel, the sabot automatically peels away, allowing the projectile's integrated cantilevered fin tails to capture air currents and spin the round into high-velocity gyroscopic stabilization. Driven by this patented aerodynamic tracking engine, the Byrna Kinetic round eliminates the severe accuracy limitations common to traditional law enforcement beanbags or erratic rubber slugs, maintaining surgical point-of-aim accuracy at distances **exceeding 100 feet** from the firing line.
Despite passing minimal physical recoil into the shooter’s shoulder, this primer-actuated projectile leaves the barrel at a blistering muzzle velocity of 312 feet per second (FPS). Due to the dense, structurally optimized weight profile of the .61 caliber polymer slug, it transfers an intense, bone-shattering **20 Joules of raw kinetic energy** straight into an active aggressor. This immense payload yields devastating stopping power—sufficient to shatter automotive glass and completely halt a dynamic threat—yet distributes the force upon impact to rebound safely rather than penetrate tissue, permitting safe defensive deployment at close-combat distances down to 5 or 6 feet. Operating with **absolutely zero gunpowder, driven solely by a high-output ignition primer**, the firing signature registers under 117 decibels. This whisper-quiet performance profile is 16 times quieter than a traditional shotgun blast, entirely removing the need for hearing protection during indoor home defense scenarios while making backyard training completely accessible.
Includes: (1) Factory-Original Box of (10) Byrna 12-Gauge Less-Lethal Kinetic Shotgun Shells (.61 Caliber Finned Polymer Slugs, 2.5-Inch Primer-Powered Hull Configuration), Complete Safety Information Guide insert, enclosed in Branded Factory Sealed Retail Staging Packaging.
*Critical Safety, Bore Compatibility & Regulatory Warning: The Byrna SS61301 Less-Lethal round is engineered strictly for standard 12-gauge shotguns utilizing Cylinder Bore or Improved Cylinder choke profiles only; never attempt to fire this ammunition through Modified Chokes, Full Chokes, Rifled Choke Tubes, or Rifled Barrels, as doing so will induce internal sabot deformation, catastrophic barrel obstructions, and severe physical harm. These specialized shells contain no gunpowder and are powered solely by a primer; consequently, they will NOT cycle the action of semi-automatic shotguns automatically. While safe to manually cycle and fire single-shot through semi-autos, they are optimized for flawless running inside pump-action and single-shot actions. Never fire at targets at ranges closer than 5 feet. For proper threat management, always aim for lower body structures (from the thorax down) to mitigate the risk of serious injury. Store ammunition exclusively inside a dry, temperate climate locker to preserve its 3-year factory warranty. Visually and physically verify your firearm is completely clear before administrative manipulation.
Key Features
- Patented Fin-Tailed Aerodynamics: Integrated cantilevered tail fins spin-stabilize the .61 caliber projectile in flight, providing pinpoint tactical accuracy up to and beyond 100 feet.
- Devastating 20-Joule Energy Transfer: Delivers nearly double the striking impact force of standard .68 caliber round launcher balls, providing intense blunt force to break auto glass and stop attackers.
- 16x Quieter Primer Activation: Completely free of gunpowder and propelled solely by a premium primer, the firing signature registers at under 117 dB to prevent acoustic disorientation indoors.
- Zero Perceived Recoil Profile: Low-pressure primer ignition entirely cures defensive weapon jump and shoulder fatigue, allowing rapid target reacquisition for users of any skill level.
- Non-Penetrating Kinetic Cushioning: Engineered to dump its entire energy payload upon impact and bounce off the target, eliminating the threat of dangerous over-penetration inside drywall boundaries.
- Universal 2.5" 12-Gauge Footprint: Dimensionally optimized to load cleanly into standard 2.5-inch, 2.75-inch, and 3.0-inch shotgun chambers across standard civilian defensive platforms.
