20 Gauge Slug Ammo

20 gauge slugs turn a light, easy-handling 20-gauge shotgun into a capable short-range deer rifle — with noticeably less recoil than a 12 gauge slug and more than enough energy to cleanly take whitetail inside typical woods ranges. For youth and recoil-sensitive hunters, shotgun-only deer zones, and anyone who wants a softer-shooting slug gun, the 20 gauge has become a genuinely popular choice. This page covers the slug types, which barrel each needs, how the 20 stacks up against the 12, and what to expect on accuracy and range.

Tatted Tacticals stocks 20 gauge slugs from Federal, Hornady, Remington, Brenneke, and Lightfield — rifled Foster slugs for smoothbores and sabot slugs for rifled barrels, in 2-3/4″ and 3″ shells. These are part of our full 20 gauge shotgun shells selection.

Slug Types: Foster, Sabot, and Brenneke

As with any gauge, the slug type dictates the barrel. Rifled Foster slugs are designed for smoothbore barrels and shoot accurately to moderate range. Sabot slugs ride a plastic sleeve that engages a rifled barrel for spin-stabilized, rifle-like accuracy at longer distance. Brenneke slugs deliver deep penetration for smoothbores, and rubber slugs serve specialized less-lethal roles. Match the slug to your barrel: smoothbore takes Foster and Brenneke; rifled takes sabot. Our 20 gauge slug guide compares the types load by load.

20 Gauge vs. 12 Gauge Slugs

The trade is recoil for raw energy. A 20-gauge slug typically launches a 5/8- to 3/4-ounce projectile, versus the roughly one-ounce slug of a 12 gauge. The 12 hits harder and reaches a bit farther, but the 20 kicks far less and remains entirely adequate for deer inside 100 yards from a smoothbore, or farther with a rifled barrel and sabot. For many hunters, that lighter recoil means better shot placement — which matters more than paper energy. Standards follow SAAMI specifications.

Range, Accuracy, and Deer Hunting

From a smoothbore with Foster slugs, expect dependable deer accuracy to roughly 75 yards; a rifled barrel and quality sabot slug extend that to 150-plus yards with an optic. Slugs are heavy and drop quickly, so zero your specific gun-and-slug combination before the season. On whitetail, a well-placed 20-gauge slug is plenty — it has cleanly taken deer for generations. For close-range work some hunters instead choose 20 gauge buckshot, and those wanting the lightest recoil of all look to the .410.

Buying 20 Gauge Slugs

Buy the slug type your barrel is built for and pattern it before hunting — point of impact varies widely between brands. Federal law sets the minimum age for shotgun ammunition at 18; some states and cities add restrictions, so per ATF guidance, confirm federal rules and review our ammunition shipping rules and state restrictions before ordering.

20 Gauge Slugs — Frequently Asked Questions

Do they make slugs for 20 gauge?

Yes, widely. Federal, Hornady, Remington, Brenneke, and Lightfield all produce 20-gauge slugs in both rifled Foster designs for smoothbores and sabot slugs for rifled barrels. They’re a popular, readily available choice for deer hunting, especially in shotgun-only zones and for recoil-sensitive hunters.

Will a 20 gauge slug drop a deer?

Yes. A 20-gauge slug delivers ample energy to cleanly take whitetail at typical ranges — out to about 75 yards from a smoothbore and farther with a rifled barrel and sabot slug. Shot placement matters more than gauge, and the 20’s lighter recoil often helps hunters shoot more accurately. It’s a proven deer load.

How far can you accurately shoot a 20 gauge slug?

From a smoothbore with Foster slugs, roughly 75 yards is a dependable maximum for deer. A dedicated rifled barrel firing sabot slugs, paired with a scope, stretches accuracy to 150 yards or more. Slugs drop quickly due to their weight, so always zero your specific gun and slug combination for the range you’ll hunt.

What hits harder, a 12 or 20 gauge slug?

The 12 gauge hits harder, launching a heavier roughly one-ounce slug with more energy and slightly more range. The 20 gauge fires a lighter 5/8- to 3/4-ounce slug with much less recoil. For deer inside 100 yards the difference is academic — both work — so many hunters choose the 20 for its comfort and easier shot placement.

What slug do I use in a smoothbore 20 gauge?

Use rifled Foster slugs or Brenneke slugs in a smoothbore barrel — they’re designed to pass safely through it and shoot accurately to about 75 yards. Do not use sabot slugs in a smoothbore; sabots require a rifled barrel to stabilize. If your barrel is smooth, Foster and Brenneke are your loads.
