Bullet Types Explained

Nosler's bonded polymer-tipped hunting bullet. Bonded core for near 100% weight retention. Polymer tip for high BC and consistent expansion.

ConstructionBonded lead-alloy core with copper jacket. White polymer tip. Bonding process ensures jacket-core integrity through barriers and bone. Controlled mushrooming to 2x original diameter.

Hardened steel or tungsten core projectile designed to penetrate body armor and light vehicle armor. Heavily regulated and largely prohibited for civilian handgun use (GCA 1968).

ConstructionSteel, tungsten carbide, or tungsten alloy penetrator core, sometimes with copper or aluminum jacket. The hard core concentrates force on a small area to defeat armor.

Inceptor's polymer-copper composite bullet. No hollow point — instead, fluted channels in the nose redirect fluid and tissue outward on impact. Extremely light and fast. Lead-free, frangible, and safe for close-range training. The ARX design produces terminal performance from radial energy transfer rather than expansion.

ConstructionInjection-molded polymer-copper matrix. No expansion — fluid dynamics redirect energy radially. Four fluted channels create hydraulic pressure. Lead-free design.

Combines tangent and secant ogive sections for reduced sensitivity to seating depth variation while retaining high BC. Dominant in PRS competition.

ConstructionHybrid ogive design: tangent nose section at base of bullet transitions to secant ogive toward tip. Reduces seating depth sensitivity vs. pure VLD. Same thin J4 jacket.

Very Low Drag projectile from Berger Bullets. Extremely secant ogive (sharp nose) for minimum drag and maximum BC. Widely used in PRS and F-Class competition.

ConstructionThin J4 jacket drawn to near-zero tip. Secant ogive with extremely low form factor. High BC (Ballistic Coefficient) for flat trajectory at long range. VLD Hunting variant expands on game.

Match-grade precision rifle bullet with a boat tail base and open tip. The open tip is a manufacturing artifact from drawing the jacket, not designed to expand (unlike defensive JHPs).

ConstructionGilding metal jacket drawn from the nose, leaving a small opening at the tip. Boat tail base reduces drag. Lead core. Open tip improves concentricity for accuracy.

Hollow point where the lead core is chemically or mechanically bonded to the jacket. Prevents core-jacket separation at high velocity or through intermediate barriers.

ConstructionLead core is bonded to the copper jacket via electrochemical process or mechanical bonding, ensuring jacket and core expand together as a single unit. Retains near 100% weight.

Lead bullet with thin copper electroplating and a hollow point cavity. Common in .22 LR and rimfire loads. The plating reduces bore fouling versus bare lead but is thinner than a true copper jacket — lower cost, suitable for small game and pest control.

ConstructionLead core with a thin electroplated copper coat. Hollow point cavity initiates expansion. Copper plating is thinner than drawn jacketing — may separate at high velocity.

Hornady's civilian defensive hollow point. Flex Tip eXpanding technology uses a soft polymer tip to prevent clogging and ensure reliable expansion from short barrels.

ConstructionPolymer-tipped hollow point. The red Flex Tip fills the hollow cavity to prevent clothing and debris clogging. On impact, tip is pushed in, initiating expansion.

Hornady's law enforcement grade barrier-blind hollow point. Heavier than Critical Defense for superior barrier penetration while passing FBI protocol.

ConstructionInterlock band mechanically locks the core to the jacket preventing separation through barriers. Polymer Flex Tip. Passes all FBI protocol barriers including auto glass and plywood.

Barnes all-copper solid hollow point for handgun calibers. Expands reliably at pistol velocities, retains approximately 100% weight, and produces no lead fragments. Popular for hunting and bear defense in handguns.

ConstructionSolid copper hollow point (Barnes X-Bullet design). Lead-free. Four petals open reliably through barriers. Deep penetration due to solid copper weight retention.

Nosler's lead-free all-copper hunting bullet. Polymer tip, relief grooves, and polymer tip for consistent expansion. Required in California and other lead-restricted areas.

Hornady's Extremely Low Drag – Match bullet. Same Heat Shield polymer tip as the ELD-X, but optimized for competition accuracy rather than terminal expansion. Very high BC. Used in Hornady ELD Match factory loads for PRS and long-range competition.

ConstructionExtremely Low Drag Match bullet. Heat Shield polymer tip (same material as ELD-X but non-expanding profile). AMP jacket for precision. Designed purely for long-range accuracy, not terminal performance.

Hornady's Extremely Low Drag eXpanding bullet. Heat Shield polymer tip resists aerodynamic heating that melts standard polymer tips at long range. Excellent BC.

ConstructionInterlock mechanically locks jacket to core. Heat Shield tip is a new polymer formulation that maintains shape at supersonic velocities unlike standard ABS polymer tips. High BC for long-range hunting.

Hornady's jacketed hollow point bullet used in their Custom and American Gunner lines. Designed for controlled, uniform expansion. Popular for handgun hunting.

ConstructionCannelured copper jacket with a serrated hollow point nose. Controlled expansion at various velocities. Weight retention typically 95%+.

US military 5.56mm standard ball projectile (SS109 design). Steel penetrator tip over lead core with mild steel penetrator. Penetrates body armor at close range. Controversial ATF classification history.

Construction62-grain FMJ with a mild steel penetrator tip over a lead core. Gilding metal jacket. Designed to penetrate Soviet steel helmets and body armor. Longer than M193, requires 1:9 or faster twist.

Lead alloyed with antimony and tin for significantly greater hardness than soft cast lead. Resists deformation and barrel leading at higher velocities. Standard for hunting and bear defense loads in revolvers and lever guns — the wide flat nose (WFN) variant maximizes wound channel diameter.

ConstructionLead alloy hardened with antimony (typically 2-8%) and sometimes tin. Does not expand. Maintains diameter through deep penetration. Preferred for dangerous game and bear defense.

Generic hollow point — an open cavity in the nose that causes the bullet to expand on impact. Covers unjacketed lead HP (.22 LR, revolver), lightly jacketed, and plated variants. For fully jacketed defensive loads, see JHP.

ConstructionLead or lead-alloy bullet with a hollow cavity in the nose. Hydraulic pressure on impact causes the cavity to expand, increasing diameter. Unjacketed HP expands at lower velocities.

Defensive and hunting projectile with a hollow cavity in the nose that causes the bullet to expand upon impact. Increases diameter and transfers energy efficiently while reducing over-penetration.

ConstructionLead core with a copper jacket that has a hollow cavity at the nose. Upon impact with soft tissue, hydraulic pressure forces the jacket petals to peel back, dramatically increasing diameter.

Similar to SP — a partially jacketed bullet with exposed lead at the nose. Common in revolver and pistol hunting loads as well as rifle hunting.

ConstructionLead core fully jacketed on the sides and base, with a partial jacket that stops short of the nose, leaving a soft lead point exposed.

Flat-nosed lead bullet for lever-action tubular magazines. Flat nose prevents recoil-initiated primer strikes in tubes. Also used for cowboy action.

ConstructionLead alloy with a flat or truncated cone nose profile. Designed for tubular magazines where pointed bullets could cause chain-fire if a recoil initiates primer contact.

All-lead hollow point projectile. Expands at low velocity without a jacket. Used in .22 LR and low-velocity revolver loads.

ConstructionLead alloy bullet with a hollow cavity in the nose. Expands at lower velocities than jacketed bullets, making it suitable for rimfire and low-pressure revolver cartridges.

Traditional all-lead pistol bullet without a copper jacket. Used for cowboy action and low-velocity range shooting. Not recommended for polygonal-rifled barrels (Glock warning).

ConstructionUncoated or wax-lubricated lead alloy bullet. Soft, low-pressure applications. Round nose profile for reliable feeding in semi-autos.

Non-expanding solid copper bullet used for deep penetration, especially on thick-skinned dangerous game. Does not deform significantly on impact.

ConstructionSolid copper (unalloyed) or copper-nickel projectile. Maintains its shape through thick hide and bone. Popular for Cape buffalo, elephant, and other thick-skinned African game.

ConstructionSingle material construction — usually C10100 copper, gilding metal, or copper-nickel alloy. Lathe-turned or swaged. Heat-treated in some designs. Relief grooves to reduce fouling.

Catch-all term for precision match bullets where the jacket is drawn from the nose end, leaving a small open tip. Accurate due to uniform jacket thickness. Common in military sniper use.

ConstructionJacket drawn from the nose to ensure uniform wall thickness and concentricity. Boat tail base. Not intended to expand — the open tip is an artifact of manufacture.

Nosler's iconic dual-core hunting bullet invented in 1946. A partition in the jacket separates two lead cores. Front core expands; rear core retains for deep penetration.

ConstructionTwo lead cores separated by a copper partition (wall). Front core is exposed and expands on impact. Rear core is fully enclosed and drives deep penetration after front expansion.

Hunting rifle bullet with a plastic tip that improves BC, initiates expansion, and protects the hollow cavity from deformation in magazines.

ConstructionHollow point jacketed bullet with a plastic tip inserted into the hollow cavity. The tip streamlines the nose for improved BC. Upon impact, the tip is driven into the hollow point to initiate expansion.

G2 Research copper projectile machined with trocar-shaped petals designed to separate and create multiple wound channels while a base slug continues for penetration.

ConstructionSingle piece machined copper. Upon impact, eight pre-cut trocar petals separate and penetrate radially while the base plug continues forward. Creates multiple simultaneous wound cavities.

Variant of the boat tail design where the boat tail diameter is reduced below the projectile body. Used in some long-range precision designs.

ConstructionLead core with a copper jacket featuring a boat tail base where the tail diameter is smaller than the body. Reduces drag while maintaining bullet stability.

Tungsten sub-caliber penetrator in a plastic sabot. Fired from standard rifle, the sabot falls away revealing a smaller, denser penetrator. Dramatically higher velocity and penetration.

ConstructionSub-caliber tungsten carbide penetrator enclosed in a plastic sabot that provides a bore-diameter fit. Sabot discards at the muzzle. Penetrator achieves much higher velocity due to lower mass.

Partial copper jacket with a lead hollow point cavity exposed at the nose. An older design — the jacket does not extend to the tip, so expansion is less controlled than modern JHP. Still effective and common in revolver and older pistol loads.

ConstructionPartial copper jacket covering the base and sides, leaving the hollow-point nose exposed. Jacket controls expansion and retains the core longer than unjacketed bullets.

Compromise between round-nose (for feeding) and wadcutter (for target cutting). Truncated cone profile punches cleaner holes than RN without wadcutter feeding issues.

ConstructionLead bullet with a forward truncated-cone shoulder and flat nose. Can be used in semi-automatic pistols unlike pure wadcutters. Cleaner target holes than round-nose bullets.

Sierra Bullets' flagship match projectile. BTHP design with extremely tight quality control. Used in world record long-range accuracy achievements and military sniper programs.

ConstructionExceptionally uniform jacket thickness and bullet diameter. Boat tail base. Open tip from the nose-first draw process. Available in a wide range of calibers and weights.

Hunting bullet with lead core exposed at the tip. Lower cost than jacketed hollow points. Reliable expansion at hunting velocities. Classic deer and general hunting bullet.

ConstructionLead core with a copper jacket that leaves the tip of the lead core exposed. Exposed soft lead tip initiates expansion upon impact with tissue.

Projectile or load loaded to remain below the speed of sound (~1,125 fps). Eliminates the ballistic crack (sonic boom) for quieter operation when used with a suppressor.

ConstructionCan be any bullet construction (FMJ, HP, solid) loaded to remain subsonic. Typically heavier-for-caliber projectiles. Most effective when paired with a suppressor.

Hornady polymer-tipped hunting bullet. Polymer tip initiates reliable expansion at a wide range of velocities. High BC for flat trajectory. Excellent deer hunting bullet.

ConstructionLead core with copper jacket. Polymer tip (same polymer as the V-MAX) fills the hollow point to initiate reliable expansion and streamline the ogive for high BC.

Federal's flagship long-range hunting bullet. Slipstream polymer tip, bonded lead core, AccuChannel groove. Designed to expand reliably from point-blank to extreme range.

ConstructionBonded lead core with a nickel-plated jacket. Slipstream polymer tip. AccuChannel groove for reduced fouling. High BC design for long-range hunting applications.

Barnes TSX with a polymer tip for improved BC and more reliable expansion at lower impact velocities. The most common Barnes hunting bullet.

ConstructionSame solid copper construction as TSX. Addition of polymer tip to streamline the ogive, improve BC, and ensure expansion initiation at low velocity impacts (250+ fps minimum).

Lead core completely enclosed in copper including the base — unlike FMJ, which leaves the lead base exposed. Eliminates airborne lead at indoor ranges. Does not expand. Speer's Lawman line is the most common example.

ConstructionLead core fully enclosed by a copper jacket including the base — unlike FMJ which leaves the base exposed. Eliminates lead vaporization at the base, reducing airborne lead in indoor ranges.

Military-spec projectile with a pyrotechnic compound in the base that burns during flight, leaving a visible trace. Used for fire adjustment and communication in military use. Civilian use restricted.
