What Does Buckshot Do to a Person?

Buckshot inflicts damage unlike almost any other type of ammunition because it launches multiple large lead pellets simultaneously, each capable of penetrating deep into the body and tearing through tissue, bone, and blood vessels along independent paths. A standard 12-gauge 00 buckshot shell releases roughly eight or nine pellets, each about 8.4 mm in diameter, and the collective energy they carry can cause catastrophic multi-organ injury at close range or a scattered constellation of individual wound channels at longer distances. The way those pellets interact with the human body depends heavily on how far away the shooter is, and the resulting injuries range from survivable peripheral wounds to near-instant death.

How Distance Reshapes the Wound

The single most important variable determining what buckshot does to a person is the distance between the muzzle and the body. At contact or near-contact range, the pellets have not yet had room to spread apart, so they enter the body as a tightly clustered mass. The result is essentially one large, devastating wound rather than many small ones. A case report of a contact shotgun wound to the chin described a split laceration measuring 15 by 2.5 centimeters down to bone, a shattered mandible, multiple broken teeth, fractured nasal bones, and massive skull fractures with pellets scattered throughout the cranial cavity.¹ The plastic wad that normally sits behind the pellets in the shell was found embedded in the brain tissue, and both subarachnoid and subdural hemorrhages covered the entire brain surface. At this range, the wound is less a series of punctures and more an explosion of tissue.

As distance increases, the pellets fan out and begin striking the body separately. Research on pellet spread from 12-gauge buckshot has found that the diameter of the pattern grows with distance, though the exact rate depends on the barrel’s choke. A tighter choke keeps pellets grouped longer; a cylinder bore allows them to spread quickly.² In one forensic case, a victim struck from roughly 3 to 7 meters suffered fatal wounds, while another person hit from 10 to 12 meters survived with multiple but less concentrated injuries to the shoulders and torso.³ That case illustrates how even a few extra meters of distance can mean the difference between a lethal wound cluster and a survivable scattering of pellet strikes.

Close-Range Destruction

When buckshot hits within a few meters, the human body absorbs an enormous amount of energy concentrated in a small area. The pellets arrive together as a single mass, essentially punching a large hole rather than drilling many small ones. Surrounding tissue is subjected to a temporary cavitation effect, where the rapid transfer of kinetic energy stretches tissue outward in a brief but violent pulse, tearing structures well beyond the physical path of the pellets themselves. Bones in the impact zone are not just fractured but comminuted, meaning they shatter into multiple fragments that become secondary projectiles inside the body.

Contact wounds carry additional markers of damage. Muzzle gas and unburned powder follow the pellets into the wound, leaving characteristic blackening and discoloration of tissues. In the case report mentioned earlier, cherry-red discoloration of the underlying tissues was visible in both the entry wound and the oral cavity, and a semicircular muzzle imprint was stamped into the skin beside the wound.¹ That gas injection also forces foreign material deep into the wound track, which creates complications for anyone who survives such an injury.

What Happens at Longer Range

Beyond roughly 10 to 15 meters, the pellet pattern has spread enough that each pellet strikes the body independently, creating its own wound channel. At intermediate distances, victims often show a central defect, a larger wound where several pellets still arrived close together, surrounded by individual “satellite” wounds where outlying pellets struck separately. As distance increases further, the central defect disappears entirely and only scattered satellite lesions remain.⁴

Each individual pellet at distance still carries enough energy to penetrate skin and muscle and, depending on the body region, to reach vital structures. A single 00 buckshot pellet is roughly the diameter of a 9mm handgun bullet, though it weighs less and travels slower at extended range. Multiple pellets hitting the torso can perforate the liver, spleen, intestines, or lungs through separate channels, creating a surgical challenge very different from a single-bullet wound. Surgeons cannot simply trace one wound track; they have to account for several independent paths of destruction, each with its own risk of vascular injury or organ perforation.

Vascular and Organ Damage

The torso is where buckshot injuries are most likely to be fatal, and the mechanism is straightforward: multiple pellets traversing the chest or abdomen can sever or lacerate major blood vessels and perforate multiple organs simultaneously. In the forensic case involving 11/0 buckshot fired from a 12-gauge at 3 to 7 meters, the victim died at the scene from massive bilateral hemothorax and aortic laceration.³ A bilateral hemothorax means both sides of the chest cavity filled with blood, and a torn aorta, the body’s largest artery, produces blood loss that is almost impossible to survive without immediate surgical intervention.

Abdominal wounds are especially treacherous because the pellets can perforate loops of intestine in multiple places, spilling gut contents into the peritoneal cavity and creating a high risk of sepsis. Unlike a single-bullet wound, where surgeons can focus on one track, buckshot forces them to inspect a wide swath of abdominal contents looking for perforations that might be separated by many centimeters. Missing even one perforation can lead to delayed peritonitis, abscess formation, and potentially fatal infection days after the initial injury.

Slug Versus Pellet Injuries

Shotguns can also fire solid slugs, which are single heavy projectiles. The wounding characteristics of slugs and buckshot pellets differ enough that surgeons approach them differently. Slugs tend to create a single, deep, high-energy wound channel with massive tissue destruction along one path, while buckshot distributes its energy across multiple tracks. A comparative review in the Wisconsin Medical Journal found that despite similarities in wound location and overall outcomes between slug and pellet injuries, the ballistic differences led to significantly different wounding characteristics and extent of injury, with important implications for surgical management.⁵ In practice, buckshot injuries tend to involve more widespread tissue exploration because of the scattered pellet paths, while slug injuries concentrate the damage along a single devastating corridor.

The Wadding Problem

A detail that often surprises people is that the pellets are not the only thing entering the body. Shotgun shells contain a plastic or fiber wad that sits between the powder charge and the pellets, serving as a gas seal and a cup that holds the pellets together during the initial moments after firing. At close range, this wad enters the wound along with the pellets. In the contact-wound case report, the plastic wad was recovered from deep within the brain.¹

Wadding is not inert once inside the body. It can trigger a local inflammatory response and carry bacterial contaminants from the barrel and the shell into the wound, making its removal a priority in surgical management.⁶ Because wadding is made of plastic or fiber rather than metal, it does not show up clearly on standard X-rays the way lead pellets do, which means surgeons and radiologists have to actively look for it. Leaving it in place raises the risk of chronic infection and abscess formation around the foreign body.

When Pellets Stay in the Body

Many buckshot survivors carry retained pellets for the rest of their lives. The decision to remove or leave them depends on where they end up. Pellets lodged in soft tissue away from joints are quickly walled off by scar tissue, which limits their interaction with surrounding structures. In these cases, surgical removal can actually cause more tissue damage than leaving them alone.⁷

The calculus changes when pellets land inside a joint, in the palm of the hand, on the sole of the foot, or in contact with a fluid-filled space. In those locations, removal is generally recommended because the ongoing mechanical and chemical interaction between lead and surrounding tissue creates problems. A systematic review of retained bullet management in the pelvis and extremities identified joint location, chronic infection, persistent pain, and lead poisoning as the primary indications for removal.⁸

Lead Poisoning from Retained Pellets

Lead poisoning from retained projectiles is uncommon but real, and it is easily missed because symptoms like fatigue, abdominal pain, cognitive difficulty, and mood changes overlap with many other conditions. Pellets sitting inside joint spaces or fluid-filled pseudocysts are most prone to causing this because the surrounding fluid gradually dissolves the lead surface, releasing it into the bloodstream.⁹ If unrecognized, lead intoxication from retained bullets can be fatal.

A study comparing blood lead levels in emergency department patients who had retained lead projectiles against matched controls found that the patients with retained shrapnel had significantly higher levels, averaging about 17 micrograms per deciliter compared to 7 in controls, with some individuals reaching 50.¹⁰ Time since injury in that group ranged from 1 to 45 years, suggesting that lead exposure is not just an early complication but a lifelong concern. For buckshot victims carrying multiple retained pellets, the combined surface area of lead in contact with body tissues is greater than for someone carrying a single bullet, which raises the theoretical risk further.

How Surgeons and Radiologists Assess These Wounds

CT scanning has become a routine part of evaluating shotgun injuries in both living patients and forensic autopsies. The imaging helps locate every pellet, identify which organs and vessels sit along each wound track, and detect complications like internal bleeding or air leaks that might not be obvious from external examination alone.¹¹ In forensic settings, postmortem CT scanning before autopsy helps characterize the wounds noninvasively and plan the most informative dissection approach.¹²

Lead pellets show up brightly on CT because of their high density, but they also create metallic artifact, a starburst of streaks on the image that can obscure nearby soft-tissue detail. When a victim has a dozen or more pellets in the abdomen, for instance, the overlapping artifacts can make it difficult to read the images around the pellets themselves. Newer dual-energy CT techniques help distinguish pellet material from surrounding tissue more cleanly, which improves both clinical and forensic analysis.

Long-Term Disability and Psychological Aftermath

Surviving a buckshot injury is only the beginning of a long medical journey. A large cohort study tracking over 8,000 firearm injury patients for an average of nearly eight years found that among those who survived intentional injuries, about one in five developed a long-term disability. Even among unintentional injury survivors, about one in ten became disabled.¹³ Those numbers reflect all firearm injuries, not buckshot specifically, but the multi-wound nature of buckshot injuries, the higher likelihood of requiring multiple surgeries, and the complications from retained pellets mean that buckshot survivors face at least comparable challenges.

The psychological toll is enormous. A study screening firearm injury survivors found that roughly 69% screened positive for risk of PTSD and 48% for depression. Most patients reported moderate to severe pain, with about three-quarters falling into those categories. Overall, 86% met criteria for at least one adverse outcome domain spanning PTSD, depression, pain, or substance use.¹⁴ Chronic pain is a particular burden for buckshot survivors, since multiple wound sites and retained pellets can create ongoing discomfort that is difficult to manage with standard pain protocols.

Rubber Buckshot and “Less-Lethal” Alternatives

Some shotgun-platform weapons are loaded with rubber or plastic projectiles intended to incapacitate without killing. These are used by law enforcement and sometimes marketed as non-lethal, but the injuries they cause can still be severe. The Flash-Ball, a rubber-bullet launcher with kinetic energy around 200 joules, was designed to avoid skin penetration, yet case reports documented major trauma to internal organs even without penetration.¹⁵ The blunt force from a high-energy impact can fracture bones, rupture organs, and cause traumatic brain injury. Standard lead buckshot delivers far more energy per pellet than these alternatives, which puts the “less-lethal” label in perspective: if rubber rounds can cause organ damage, conventional buckshot’s capacity for destruction is on a different scale entirely.

Bean-bag rounds, another common less-lethal shotgun load, work on a similar principle: they deliver blunt impact without penetration. But at close range, even bean bags can penetrate skin and cause fatal injuries. The underlying lesson is that any projectile launched from a shotgun barrel at typical muzzle velocities carries enough energy to cause serious harm. The pellet material changes the wound profile, with lead penetrating deeply and rubber spreading its force over a wider area, but the human body’s tolerance for sudden kinetic energy transfer is limited regardless of what is hitting it.

Why Buckshot Wounds Are Surgically Complex

From a surgeon’s perspective, a buckshot wound is not simply “a gunshot wound.” It is a cluster of gunshot wounds arriving simultaneously. Each pellet follows its own trajectory after entering the body, and pellets that enter just centimeters apart on the skin surface can diverge widely once inside, striking different organs, ricocheting off bone, and coming to rest in unpredictable locations. The surgical team cannot trace a single wound track the way they would with a handgun or rifle bullet. Instead, they have to systematically inspect every structure in the zone of injury, sometimes requiring exploratory surgery to rule out hidden perforations.

The infection risk is also higher than with single-bullet wounds. Buckshot carries clothing fragments, skin bacteria, and wadding material deep into tissue through multiple entry points, creating several potential infection foci at once. High-energy wounds generally require debridement, the removal of dead and contaminated tissue, and the multi-track nature of buckshot injuries makes that debridement more extensive. For pellets that have come to rest in soft tissue without joint involvement, surgeons generally leave them in place rather than causing additional tissue trauma to retrieve them, as noted earlier. But the overall management is more resource-intensive and the hospital stays tend to be longer compared with single-projectile injuries.

Estimating shooting distance after the fact is also harder than most people assume. While it is intuitive to think a forensic examiner could simply measure the spread of wound holes and calculate how far away the shooter was, research on this approach has found it to be unreliable, particularly when only a few wound holes are available for measurement. The pattern depends on too many variables, including choke, barrel length, ammunition brand, and intervening barriers, for a simple spread-equals-distance formula to work.² Forensic investigators often turn to experimental test-firing with the same weapon and ammunition to reconstruct the most likely range.³
