Description
The Brenneke Close Encounter 410 GA Slug turns a revolver chambered for .410/.45 Colt into a far more serious tool. Brenneke designed this round for the popular 2-1/2 inch .410 revolvers that many owners keep for the truck, the trail and the nightstand. Instead of a spread of small pellets, it sends a single 1/4 oz (109 grain) solid lead slug downrange at a rated 1500 feet per second, producing about 578 foot-pounds of energy. The large frontal area and heavy mass deliver far more power than a typical shotshell while recoil stays manageable in a handgun.

Why Shooters Pick This 410 Revolver Slug

Solid lead Brenneke slug with angled ribs that help it pass smoothly through chokes
Patented design in which the rear portion slides into the point on impact for deep, controlled performance
Packed 5 rounds per box, a practical quantity for testing point of impact and stocking a carry gun
Brenneke Close Encounter 410 GA Slug Performance
Rated muzzle velocity of 1500 fps from the factory
About 578 ft-lbs of muzzle energy from a 1/4 oz projectile
Large frontal area for a wide wound channel
Tight groups at typical defensive and small game distances
If you have been searching for a 45 colt 410 slug that is worth carrying, this one is designed around exactly that platform. Brenneke tuned the payload and the 2-1/2 inch shell length so the round fits standard revolver cylinders without binding, and the rimmed hull extracts cleanly when you dump empties. Because the slug is a solid lead design rather than a sabot, there is no plastic sleeve that has to separate before the projectile stabilizes, which helps from a short barrel.
Store these shells in a cool, dry place in their original box so the lot number stays with the ammunition. Check local regulations before using slugs for hunting, and confirm your firearm is marked for 2-1/2 inch .410 shells. A short session at the range with a few targets set at 10, 15 and 25 yards will show you exactly where the slug prints from your gun and how quickly you can recover between shots.

Why Choose a Slug for Home Defense 410 Guns
Birdshot from a short revolver barrel spreads quickly and carries little energy, which limits its value when a threat is close. A single heavy slug concentrates all of that energy into one projectile, giving a .410 revolver or shotgun a much stronger answer for snakes, predators or an intruder. Brenneke has made slugs for well over a century, and the Close Encounter carries the same quality control and consistent lot-to-lot performance the company is known for.
Many owners also like this load as trail gun ammo. A revolver that can fire .45 Colt or .410 shells is already versatile, and a box of these slugs lets you carry one gun that covers pests, small game and personal protection. Keep a cylinder of slugs loaded and a few shotshells in reserve for whatever the day brings.
Owners of Taurus Judge, Smith & Wesson Governor, Bond Arms and similar .410/.45 Colt handguns will appreciate what this load adds to their gun. It is equally at home in a single-shot or pump 410 shotgun kept by the back door on a farm or ranch. As with any defensive round, fire a few through your own gun first to confirm point of impact and reliable function before you depend on it.
