When you’re tracking through Tennessee’s hardwood forests or setting up for a morning hunt along the Mississippi River bottomlands, you need shotgun ammunition that delivers consistent, reliable performance. The Brenneke TKO 12 Gauge, 2.75-inch, lead-free 2/3 ounce slugs, packed in a 5-round box, offer a practical choice for hunters and shooters who want effective stopping power without the environmental concerns of traditional lead projectiles. Whether you’re managing deer populations in the Cumberland Plateau or keeping a defensive option ready near Nashville, these slugs are built to perform in the conditions Tennessee shooters face.
What This Product Is and Who It’s For
The Brenneke TKO (Tactical Knock Out) 12 Gauge slug is a lead-free, 2/3-ounce projectile designed for use in 2.75-inch chambers. This ammunition is intended for hunters focused on deer or other medium-to-large game, as well as for shooters who want a reliable defensive load for home protection. It also appeals to target shooters who practice with slug loads to maintain proficiency, and to collectors who appreciate Brenneke’s engineering heritage. The lead-free construction makes it a suitable option for those who shoot in areas with restrictions on lead ammunition, or who simply prefer to reduce their environmental footprint.

Feature Deep-Dive
The Brenneke TKO slug uses a lead-free alloy construction that provides consistent expansion and penetration across a range of velocities. This is not a frangible round; it is designed to hold together through barriers like light brush or heavy clothing, making it a practical choice for hunting in Tennessee’s varied terrain. The solid construction reduces the risk of core-jacket separation, which can occur with some lead-core slugs, and ensures that the projectile retains its mass for deeper penetration on game.
The 2/3-ounce weight strikes a balance between manageable recoil and effective energy transfer. In a standard 12-gauge pump or semi-automatic shotgun, this load produces recoil that most shooters can handle for multiple rounds at the range or in the field. The velocity profile is optimized for 2.75-inch chambers, so you get consistent performance without the added pressure of magnum loads. This makes the TKO a versatile option for shooters who use a single shotgun for hunting, defense, and practice.
Brenneke’s rifled slug design features a deep, helical pattern that imparts spin on the projectile as it travels through a smoothbore barrel. This spin stabilizes the slug in flight, improving accuracy at typical hunting and defensive distances—out to 75 yards or more with a properly zeroed shotgun. The slug’s ogive shape reduces drag, helping it maintain velocity and energy downrange. For shooters using a rifled barrel, the TKO benefits from the additional stabilization, offering even tighter groups.
The lead-free composition is a notable feature for Tennessee shooters who hunt on public lands or in areas with lead restrictions. The alloy used is dense enough to deliver the same terminal performance as traditional lead slugs, while being non-toxic to wildlife and the environment. This means you can use the TKO in sensitive habitats without concern for secondary poisoning or regulatory issues. The material also resists deformation during feeding in pump-action shotguns, reducing the chance of a jam when you need the gun to cycle reliably.
Each round in the 5-round box is loaded to consistent specifications, with careful attention to powder charge and crimp quality. Brenneke has been manufacturing shotgun ammunition since 1898, and the TKO line reflects their experience in producing slugs that function in a wide range of firearms. The hull is designed to extract cleanly from chambers, even after extended storage or exposure to humidity common in Tennessee’s climate. The non-corrosive primers ensure that your firearm’s bore and action remain free of residue that can lead to rust over time.
For shooters who prioritize reliability, the TKO’s construction includes a reinforced base wad that helps manage recoil forces and keeps the slug aligned with the bore during ignition. This reduces shot-to-shot velocity variation, which translates to more consistent point of impact. Whether you are sighting in your shotgun before deer season or testing defensive loads, this consistency means fewer surprises when you squeeze the trigger.
Ideal Use Cases
- Deer Hunting: The 2/3-ounce slug delivers sufficient energy for clean kills on deer-sized game at typical shotgun ranges.
- Home Defense: The lead-free construction reduces ricochet risk in indoor environments, and the slug’s stopping power is effective against threats.
- Range Practice: Manageable recoil and consistent accuracy make the TKO a good choice for training with slug loads.
- Wilderness Protection: When hiking or camping in bear or wild hog country, a shotgun loaded with TKO slugs provides a reliable deterrent.
Compatibility Notes
This ammunition is designed for use in any 12-gauge firearm with a 2.75-inch chamber, including pump-action, semi-automatic, break-action, and bolt-action shotguns. It functions reliably in smoothbore barrels as well as rifled barrels. For best accuracy, test the TKO in your specific firearm to determine point of impact. This ammunition is not recommended for use in shotguns with 3-inch or 3.5-inch chambers unless the manufacturer specifies 2.75-inch compatibility. No special holsters or magazines are required, as this is a standard shotshell. For storage, keep ammunition in a cool, dry place away from direct sunlight to maintain primer and powder integrity.
