Shotgun gel tests look nothing like pistol or rifle tests. Instead of one bullet, you may see eight, nine or fifteen pellets tunnel through the block. Or you may see one big slug. That makes 12 gauge ballistic gel results harder to read, and easier to misread. This guide shows you what to look at, so you can choose a home-defense or hunting shell with clear eyes.
Bulk Ammo Vault has not run its own gel tests. We don’t publish penetration or spread numbers for specific shells. Below, you’ll find how gel testing works for shotguns, what changes the results, and how the defensive 12 gauge loads on our shelf compare on build and listed velocity.
How Gel Testing Works With a Shotgun
The gel itself is the same: calibrated 10% ordnance gelatin, chilled and checked with a steel BB before use. What changes is what you measure.
- Buckshot: testers count how many pellets hit the block, then measure how deep each one went. Some note the spread on the face of the block.
- Slugs: testers measure depth, expanded width and recovered weight, like a rifle bullet.
- Combo loads: shells that hold a slug plus buckshot pellets are judged on both.
The FBI protocol calls for 12 to 18 inches of penetration. It was built for handgun ammo, but many shotgun testers use the same window as a benchmark for each pellet.
Reading Buckshot Results
Pellet size matters most
Buckshot sizes run from #4 Buck, the smallest common size, up through #1, #0, 00 and 000. Bigger pellets carry more mass each, so they tend to drive deeper. Smaller pellets put more holes in the target but each one carries less. That’s the core trade-off you’ll see in any gel chart.
Birdshot is much smaller still. Its pellets are light and lose speed fast in gel. That’s why most defense instructors steer people toward buckshot or slugs for home defense.
Pellet count and spread
A standard 2-3/4 inch 00 Buck shell holds 8 or 9 pellets. A 3-inch shell may hold 12 to 15. More pellets is not always better. Every pellet that misses the target is still going somewhere. Pattern your gun at home-defense distances to see where they land.
Wads that tighten patterns
Some shells use special wads that hold the pellets together longer. Federal’s FliteControl wad is one example. Hornady uses its Versatite wad. Tighter patterns make it easier to keep every pellet on target.

Look at the velocity column. The Hornady Critical Defense 00 Buck lists 1,600 fps. The Federal Reduced Recoil 00 Buck lists 1,145 fps. Reduced recoil loads trade some speed for faster follow-up shots and easier handling. In gel, slower pellets may stop a bit sooner. Many shooters accept that for better control.
Plated pellets matter too. The Federal Force X2 00 Buck uses copper-plated lead pellets. Plating helps pellets hold their shape. Rounder pellets tend to fly straighter and push deeper.
Reading Slug Results
A 1-ounce slug is about 437 grains. It hits hard and pushes deep. That’s the strength and the risk. In a home, a slug that misses or passes through can travel a long way. Read slug gel results with walls and neighbors in mind.
| Load | Bullet | Payload | Shell | Velocity |
|---|---|---|---|---|
| Winchester PDX1 Slug 12 Gauge Defender 1 oz Segmenting | Segmenting (fragmenting) rifled slug | 1 oz slug | 2-3/4 in. | 1,600 fps |
| Fiocchi Aero Slug 12 Gauge High Velocity 1 oz | Rifled slug | 1 oz slug | 2-3/4 in. | 1,560 fps |
| Brenneke Tactical Home Defense 12 Gauge Reduced Recoil 1 oz Slug | Slug | 1 oz slug | 2-3/4 in. | 1,378 fps |
| Winchester PDX1 Defender 12 Gauge Slug and 00 Buck 2-3/4″ | 1 oz rifled slug + 3 #00 buckshot pellets | #00 Buck (3 pellets) | 2-3/4 in. | 1,150 fps |
The Winchester PDX1 Segmenting Slug lists 1,600 fps. It’s designed to break into segments on impact. The Winchester PDX1 Defender slug and 00 Buck combines a 1-ounce slug with three 00 pellets, at 1,150 fps. The Brenneke Tactical Home Defense Reduced Recoil Slug lists 1,378 fps.

What Throws Off Shotgun Gel Results
- Distance. Pellets spread and slow as range grows. A test at 7 yards won’t match one at 25.
- Barrel and choke. A tight choke holds patterns together. Check the choke used in any test. Some loads say to use cylinder or improved cylinder.
- Heavy clothing. Layers of denim and fleece can slow pellets. Look for tests that include clothing.
- Shell length. A 3-inch shell needs a 3-inch chamber. Never fire a longer shell than your gun is marked for.
- Sample size. One shot shows little. Good tests fire several.
Choosing a 12 Gauge Home-Defense Load
- Start with a 2-3/4 inch 00 Buck defense load from a known maker.
- If recoil is a problem, try a reduced recoil version.
- Pattern it at the distances inside your home.
- Run a box through your gun to make sure it cycles, especially in a semi-auto.
Laws on self-defense and on hunting with buckshot or slugs vary. Check your state and local rules. For hunting, also check which shot types are allowed for each species. For a full buckshot overview, read our 12 gauge buckshot ammo guide.

Frequently Asked Questions
How many pellets in 00 buckshot?
It depends on the shell. A standard 2-3/4 inch 12 gauge 00 Buck load holds 8 or 9 pellets. Some 2-3/4 inch magnums hold 12. A 3-inch shell often holds 12 to 15, and a 3-1/2 inch shell can hold 18. The box lists the count.
What is buckshot used for?
Buckshot is used for home defense, law enforcement and hunting larger game such as deer or coyotes where the law allows it. Its large pellets carry more energy each than birdshot. Hunting rules on buckshot vary, so check your state’s regulations first.
What choke for buckshot?
Many buckshot loads pattern well from cylinder or improved cylinder chokes. Some loads with special wads, like FliteControl, are designed for open chokes and can pattern tighter than you expect. Pattern your shotgun with your chosen load at the distances you plan to shoot.
Is ballistic gel accurate for shotgun loads?
Calibrated gel gives a fair, repeatable way to compare pellet depth and slug behavior. It does not show bone, distance changes or pattern spread on a real target. Use gel results to compare loads, then pattern your own shotgun.
Is birdshot good for home defense?
Most defense trainers recommend buckshot or slugs over birdshot. Birdshot pellets are small and light, so they lose speed quickly in tissue-like material. Laws on self-defense vary, so check your state and local rules.
