The process of a bullet expanding on impact with a target is commonly referred to as mushrooming, due to the resulting shape resembling a mushroom. Hollow-point bullets, soft-point bullets, and ballistic-tipped bullets are some of the types of bullets that mushroom. The expansion of the bullet increases its frontal surface area, limiting its depth of penetration and causing more extensive tissue damage. This makes mushrooming bullets ideal for hunting and police use, as they increase the chance of a quick kill and reduce the risk of accidental injury to bystanders.

Hollow-point bullets are a common type of bullet that expands on impact, creating a mushroom shape
Hollow-point bullets are designed to expand upon impact with a soft target, transferring the projectile's energy into the target over a shorter distance. This controlled penetration is particularly useful in situations where over-penetration could cause collateral damage, such as aboard an aircraft. The expansion also slows down the bullet, further reducing the risk of accidental penetration through an exit wound.
The design of hollow-point bullets varies to achieve controlled expansion. Some have jackets that are thinner at the front than the rear, allowing for easy initial expansion followed by a reduced expansion rate. Others use partitions in the middle of the bullet core to control the expansion or bond the lead core to the copper jacket to prevent separation and fragmentation.
Hollow-point bullets are widely used by civilians and police due to their reduced risk of bystander injury and increased speed of incapacitation. They are particularly effective for hunting thin-skinned game, providing quick kills and reducing the risk of blood trails. However, they may not be suitable for larger game, as they can come apart, resulting in insufficient penetration.
While hollow-point bullets offer advantages in certain situations, they also have some drawbacks. They may not always expand reliably, especially when passing through thick clothing or tough hides, as the material can clog the cavity. Additionally, they may experience accuracy issues at extreme distances due to aerodynamic considerations.

Soft-point bullets are another type of expanding bullet, flattening out to create a mushroom pattern
Soft-point bullets are a type of expanding bullet, designed to flatten out and create a mushroom pattern upon impact with a target. This is in contrast to non-expanding projectiles, which are what people generally think of when they hear the word "bullet". These non-expanding bullets are typically used in target shooting and are made from a lead core with a hard metal exterior, which helps them retain their shape.
Expanding bullets, on the other hand, are designed to increase in diameter upon impact, resulting in a larger wound and more damage to the target. This increased diameter also slows the bullet down, reducing the risk of accidental injury to bystanders. Soft-point bullets are one of the two main types of expanding bullets, the other being hollow-point bullets.
Hollow-point bullets are the more common type of expanding bullet and feature a concave tip. They are widely used by civilians and police due to their reduced risk of bystander injury and increased speed of incapacitation. Hollow-point bullets are also more accurate than other types of ammunition, making them useful for target shooting. However, they are banned from wartime use due to the extensive tissue damage they cause.
Soft-point bullets, meanwhile, typically have a lead core surrounded by a soft metal case. When they hit a target, they flatten out to create a mushroom shape, in contrast to hollow-point bullets, which collapse. The speed of the bullet also affects the expansion; at different velocities, a bullet will expand to a different extent.
While soft-point bullets are less common than hollow-point bullets, they offer a unique set of advantages. By flattening out upon impact, soft-point bullets create a wider frontal surface area, limiting their penetration depth and causing more extensive tissue damage. This makes them particularly effective for hunting, as their increased stopping power results in a quicker kill.

Full Metal Jacket (FMJ) bullets are fully encased in metal and do not mushroom on impact
Full Metal Jacket (FMJ) bullets are fully encased in metal and do not mushroom upon impact. They are designed to penetrate targets without significant expansion, maintaining their shape and allowing for deeper penetration. This makes them ideal for target shooting, as they provide a straight passage through the target and a neat entry, but less ideal for self-defence scenarios.
FMJ bullets are characterised by a soft lead core that is fully encased in a harder metal jacket, typically copper or a copper alloy, though other materials can be used. This design ensures the lead core is protected, resulting in reduced barrel fouling and consistent ballistics. The metal casing prevents the lead from depositing in the gun barrel as the bullet is fired, reducing barrel wear and improving feeding reliability in semi-automatic firearms.
The non-expanding nature of FMJ bullets means they can pass through a target without causing as much tissue damage as expanding bullets, such as hollow point or soft point bullets. This can limit their effectiveness for hunting or self-defence purposes, as they may not cause enough damage to incapacitate an attacker or bring down prey. Additionally, their ability to penetrate targets without mushrooming can pose a risk of over-penetration, potentially striking an unintended target.
FMJ bullets were designed in the late 1800s for use in military rifles. The Hague Convention of 1899 made it illegal to use bullets that easily expand or flatten inside the body, and FMJ bullets were likely to cause a "through and through" wound instead of mushrooming and causing more grievous harm. Today, FMJ ammunition is commonly used for target shooting, training, and in some military and law enforcement operations. It is also used for hunting small game, though hunters generally prefer bullets that expand to cause more internal damage and reduce blood trails.

Round nose flat-point bullets are similar to FMJs but have a flat tip. They also do not mushroom
Bullets are typically categorized into two types: expanding and non-expanding. Expanding projectiles are designed to collapse and expand outward upon impact, imparting more force onto the target. Non-expanding projectiles, on the other hand, maintain their shape and do not mushroom. One such example of a non-expanding projectile is the round nose flat-point bullet.
Round nose flat-point bullets are fully encased in a metal jacket but feature a distinct flat tip that resembles a hollow point. Unlike other expanding bullets, round nose flat-point bullets do not mushroom upon impact. Instead, they retain their shape, making them a popular choice for target shooters. These bullets are often used by individuals seeking an old-school experience with firearms such as lever-action rifles or single-action revolvers.
While round nose flat-point bullets share similarities with Full Metal Jacket (FMJ) bullets, they differ in their tip design. FMJ bullets are the most common type of projectile and are extensively used in training and target practice. In contrast, round nose flat-point bullets offer improved stopping power, making them suitable for revolver and pistol ammunition.
The versatility of round nose flat-point bullets is highlighted by their ability to adapt to various calibers and their compatibility with a wide range of casings and jackets. This adaptability contributes to their reputation as a "jack of all trades, master of none." Despite their versatility, these bullets are primarily chosen for target shooting due to their accuracy and ability to create clean, easily visible holes in paper targets.
In summary, round nose flat-point bullets are unique in their ability to maintain their shape upon impact, setting them apart from expanding projectiles that mushroom. Their flat-tip design, versatility, and accuracy make them a preferred choice for target shooters and enthusiasts seeking an authentic, old-school shooting experience.

Ballistic tip bullets are related to hollow points but have inserts that help them mushroom
Hollow-point bullets are designed to expand or "mushroom" upon impact with a target. They have a cavity or depression in their tip, which causes them to expand outward, increasing the axial diameter of the projectile as it passes through. This process is called mushrooming because the resulting shape resembles a mushroom, with a widened, rounded nose on top of a cylindrical base. Hollow-point bullets are used for controlled penetration, where over-penetration could cause collateral damage. They are also more accurate than other types of ammunition due to their reduced sensitivity to wind deflection and bullet harmonic characteristics.
Ballistic tip bullets are a type of projectile related to hollow points. They feature a special insert, typically made of polymer or plastic, that assists in the mushrooming process when the bullet hits a target. These inserts address a key issue with traditional hollow points: inconsistent expansion when passing through barriers like clothing. The insert acts as a wedge, ensuring reliable expansion and improving the bullet's aerodynamic efficiency, resulting in flatter trajectories.
While hollow-point bullets are commonly used in civilian and law enforcement contexts due to their effectiveness and safety advantages, ballistic tip bullets are often chosen for hunting applications. Hunters seek to maximize internal damage to their targets, which is achieved through the reliable expansion and increased penetration depth provided by the inserts in ballistic tip bullets.
The choice between hollow-point and ballistic tip bullets depends on the specific needs of the user. Hollow-point bullets are versatile and suitable for self-defense, hunting, and law enforcement applications. They offer improved stopping power and reduced risk of over-penetration. On the other hand, ballistic tip bullets excel in hunting scenarios, providing consistent expansion and deeper penetration, resulting in more internal damage to the target.
In summary, both hollow-point and ballistic tip bullets are designed to mushroom upon impact. Ballistic tip bullets build upon the design of hollow points by incorporating inserts that enhance their expansion capabilities and improve their aerodynamic performance. This refinement makes them particularly effective in hunting situations where maximizing internal damage to the target is a priority.
