Brenneke Magnum 20 GA 3 in Slug – Powerful 1 oz Deer Slug, 1476 fps, 5 Rounds

Description

The Brenneke Magnum 20 GA 3 in Slug lets a three-inch 20 gauge hit like many 12 gauge loads. Brenneke loads a full 1 oz (437 grain) solid lead slug on top of three inches of magnum powder, and the result is a rated 1476 feet per second with roughly 2120 foot-pounds of muzzle energy. That is one of the heaviest and most powerful slugs available for the 20 gauge. Velocity and energy both stay strong to 100 yards and beyond, and the flat trajectory means you rarely need to think about holding high or low at typical deer distances.

Brenneke Magnum 20 GA 3 in Slug Performance

Rated muzzle velocity of 1476 fps

About 2120 ft-lbs of muzzle energy

Flat trajectory slug that stays on target past 100 yards

Strong knockdown power on deer and hogs

Clean the bore between range sessions, since lead and plastic fouling can open up groups. Let the barrel cool between strings of shots so heat does not shift your point of impact, and always confirm your chamber is marked for 3 inch shells before loading.

A 100 Yard Shotgun Slug for the 20 Gauge

A 20 gauge is lighter to carry and easier on the shoulder than a 12, which is why so many hunters choose one for long days on stand. The usual trade-off has been range and power. This load closes much of that gap. With a heavy deer slug moving this fast, a well-sighted 20 gauge can make clean shots across a field edge or a cut line where lighter loads would drop off quickly.

Brenneke has made slugs in Germany since 1898, and consistent weight from round to round is a big part of why these loads group well. Because the slug is a full-bore lead design with an attached wad, it does not rely on a sabot to stabilize, so it can be fired through smooth or rifled barrels.

Deer and hog hunters who carry a 20 gauge with a 3 inch chamber will get the most from this load, especially in shotgun-only zones where shots can stretch out. It is a strong upgrade for anyone who wants more reach without moving to a heavier 12 gauge. Follow all federal, state and local hunting regulations when using this ammunition.

Store these shells in a cool, dry place in the original box so the lot number stays with the ammunition. Before the season, confirm point of impact at 50, 75 and 100 yards with the same lot you plan to hunt with, and note any change from your usual load.

Shot placement still matters more than raw power. A set of rifle-style sights or a low-power optic makes precise aiming far easier than a bead, and a steady rest at the range shows what your barrel and this load can really do. Recoil from a 3 inch load in a light 20 gauge is noticeable, so a good recoil pad helps.
