Types of Bullets: FMJ, Hollow Point, Soft Point, Slugs, and More

Different bullet types are designed for different jobs: target practice, hunting, defensive use, competition, and specialized shooting. The right choice depends on the firearm, caliber, barrel, local law, target type, backstop, and manufacturer guidance.

This guide explains common bullet styles in plain language. It does not cover handloading recipes, pressure data, or tactical advice. Always use ammunition that matches the firearm marking and owner’s manual, and follow all range and hunting rules.

Bullet Basics

The bullet is the projectile that leaves the barrel. It is only one part of a cartridge, which also includes the case, primer, and powder. Hunter Ed’s firearm ammunition overview is a useful starting point for understanding those parts.

Bullet design can affect feeding, accuracy, expansion, penetration, recoil feel, and the type of backstop needed. Do not assume that two bullets with the same caliber marking behave the same way. Bullet weight, shape, jacket material, construction, and velocity all matter.

For a broad technical overview, see the general reference on bullets. For real use, the firearm manual and ammunition maker’s guidance matter more than general descriptions.

Full Metal Jacket Bullets

Full metal jacket bullets, often called FMJ, usually have a lead core covered by a harder metal jacket. They are common for range practice because they feed well in many firearms and are widely available.

• Common use: target practice, training, and some competition formats.
• Strength: reliable feeding and consistent range performance in many firearms.
• Watch point: FMJ bullets may penetrate more than some expanding designs, so a safe backstop matters.

FMJ is not automatically the best choice for every use. Match the ammunition to the firearm, range rules, and purpose.

Hollow Point Bullets

Hollow point bullets have a cavity in the nose. Many are designed to expand in suitable media, though actual performance depends on design, velocity, barrier, and target conditions. Do not assume every hollow point performs the same way.

• Common use: hunting or defensive ammunition, depending on caliber and law.
• Strength: controlled expansion may be part of the design goal.
• Watch point: reliability and point of impact should be tested safely with the firearm before relying on a load.

Some areas restrict certain ammunition types for hunting, carry, or range use. Check current law and local rules before buying or using hollow points.

Soft Point Bullets

Soft point bullets have exposed lead or a softer nose area with a jacket around much of the bullet. They are often associated with hunting ammunition because many designs are intended to expand while still giving useful penetration.

• Common use: hunting rifles and some older ammunition styles.
• Strength: balance of expansion and penetration in suitable applications.
• Watch point: match bullet construction to game size, distance, and legal requirements.

For hunting, use ammunition that is legal for the species and location. Ethical shot placement, backstop awareness, and range limits matter as much as bullet design.

Polymer Tip and Ballistic Tip Bullets

Polymer tip bullets use a plastic tip to help shape the bullet nose. Depending on design, the tip may improve aerodynamics, protect the nose, or help initiate expansion. These bullets are common in some hunting and long-range target loads.

• Common use: hunting, varmint shooting, and some target loads built for tight groups.
• Strength: streamlined shape and design-specific terminal behavior.
• Watch point: different polymer tip bullets are built for different tasks, so read the ammunition maker’s description carefully.

A polymer tip does not tell the whole story. Jacket thickness, core design, weight, and velocity are part of the performance picture.

Wadcutter and Semi-Wadcutter Bullets

Wadcutter bullets have a flat front that cuts clean holes in paper targets. Semi-wadcutters keep a flat shoulder but have a more tapered nose. These shapes are common in some handgun target and competition contexts.

• Common use: paper target shooting and some revolver loads.
• Strength: clean target holes that are easier to score.
• Watch point: some semi-auto pistols may not feed certain flat-nose designs reliably.

Shotgun Slugs and Specialty Projectiles

A shotgun slug is a single projectile fired from a shotgun. Slugs are different from birdshot or buckshot, and they require the right gauge, chamber length, choke compatibility, and sighting setup. Always check the barrel markings and manual before using slugs.

Other specialty projectiles exist, but they should be treated carefully. Use only ammunition that is safe and legal for your firearm and purpose. If you are unsure, contact the firearm or ammunition maker.

Safety and Selection Tips

Ammunition selection is a safety decision. Use the NSSF firearm safety rules every time you handle ammunition or firearms, and make sure you have a safe backstop for the bullet type and shooting location.

• Match the caliber and cartridge exactly to the firearm marking and manual.
• Follow range rules for allowed bullet types and backstops.
• Use hunting ammunition that is legal for the game and location.
• Test reliability and point of impact safely before relying on a load.
• Do not use damaged, corroded, unknown, or reloaded ammunition unless you fully trust the source and data.
• Store ammunition away from heat, moisture, and unauthorized access.

FAQ

What is the difference between a bullet and a cartridge?

The bullet is the projectile. The cartridge is the complete round, including the bullet, case, primer, and powder.

Are FMJ bullets good for practice?

FMJ bullets are commonly used for practice because they are widely available and feed well in many firearms. Use them only where the range and backstop allow them.

Are hollow points only for handguns?

No. Hollow point designs exist for both handgun and rifle ammunition. The use depends on the cartridge, bullet construction, firearm, law, and purpose.

Can I use any bullet type in my firearm?

No. Use only ammunition that matches the firearm marking and manual. Bullet shape, pressure, chambering, and firearm design all matter.

Which bullet type is best for hunting?

It depends on game size, caliber, distance, local law, and bullet construction. Use legal hunting ammunition designed for the species and verify performance safely before the hunt.
