Comprehensive Glossary of Bullet Construction Types

TermManufacturerDescriptionPurposeApplications
FMJ (Full Metal Jacket)GenericA soft core (often lead) encased in a harder metal shell.Reliable feeding, reduced barrel fouling, non-expanding.Military, training, target shooting.
JHP (Jacketed Hollow Point)GenericA jacketed bullet with a hollow cavity in the nose for controlled expansion.Expands on impact, increasing stopping power.Self-defense, law enforcement, hunting.
SJHP (Semi-Jacketed Hollow Point)GenericPartial jacket with an exposed lead hollow point for rapid expansion.Greater expansion and energy transfer.Hunting and self-defense.
SP (Soft Point)GenericJacketed bullet with an exposed soft lead tip.Controlled expansion and deeper penetration.Hunting medium-to-large game.
BT (Boat Tail)GenericA bullet with a tapered rear end for improved aerodynamics.Enhances ballistic coefficient and long-range accuracy.Long-range shooting.
AP (Armor Piercing)GenericHardened steel or tungsten core for penetrating armor.Designed to defeat armored targets.Military and law enforcement.
MatchVariousPrecision bullets optimized for consistent accuracy.Competitive shooting and long-range precision.Match shooting and sniping.
Polymer TipVariousBullet with a polymer tip to improve aerodynamics and initiate expansion.Enhances accuracy and terminal performance.Hunting and precision shooting.
Bonded CoreGenericA chemically or mechanically bonded core and jacket.Retains weight and ensures deep penetration.Big game hunting, law enforcement.
SolidGenericMade entirely of a single material, often brass or copper.High weight retention, straight penetration.Dangerous game hunting.
FrangibleGenericDesigned to break apart on impact with hard surfaces.Reduces ricochet and over-penetration.Training, close-quarters combat.
OTM (Open Tip Match)GenericMatch-grade bullet with a small hollow point, not designed for expansion.Maximized precision and aerodynamics.Competitive shooting, military sniping.
VarmintGenericLightweight, thin-jacketed bullet designed to fragment on impact.Causes massive tissue damage on small game.Varmint and predator control.
LRX (Long Range X-Bullet)Barnes BulletsSolid copper with a polymer tip and optimized boat-tail for long-range performance.Reliable expansion at long range and lower velocities.Long-range hunting.
TTSX (Tipped Triple Shock X)Barnes BulletsSolid copper bullet with a polymer tip and expansion grooves.Combines accuracy, penetration, and weight retention.Hunting large game, precision shooting.
TSX (Triple Shock X)Barnes BulletsSolid copper hollow-point bullet with expansion grooves.Deep penetration and consistent expansion.Dangerous game and large game hunting.
ELD-X (Extremely Low Drag – Expanding)HornadyPolymer-tipped bullet with heat-shield tip for long-range precision and expansion.Maximizes accuracy and terminal energy.Long-range hunting.
ELD-M (Extremely Low Drag – Match)HornadySimilar to ELD-X, but designed purely for match shooting without controlled expansion.Extreme accuracy for long-range competition.Precision matches.
VLD (Very Low Drag)Berger BulletsBullet with an aerodynamic design for superior drag reduction.Improves velocity retention and accuracy over distance.Long-range shooting, competitions.
AccuBondNoslerBonded-core bullet with a polymer tip and boat-tail for controlled expansion.Combines penetration and accuracy.Medium-to-large game hunting.
PartitionNoslerDual-core bullet with a solid partition for controlled expansion and deep penetration.Reliable performance on tough game animals.Hunting dangerous game.
A-FrameSwift BulletsBonded dual-core bullet similar to Nosler’s Partition.High weight retention and controlled expansion.Dangerous game hunting.
