AP: armor-piercing Military bullets with steel or tungsten core that penetrates steel armor. Bullet's tip is usually painted black for easier identification. API: armor-piercing incendiary Designed to penetrate armor and set target on fire. Tips are usually painted light blue. BBWC: bevel-base wad cutter Pistol bullet that's flat on both ends; has beveled base to increase accuracy similar to a boat-tail bullet. BEB: brass-enclosed base Pistol bullet with brass plug over exposed lead base to reduce lead exposure. Many indoor ranges now specify use of this bullet to decrease lead contamination. BJHP: brass-jacketed hollow point Defensive pistol bullet that controls mushrooming and energy release over longer distances. BST: Ballistic Silver tip Used with hunting rifles, this Winchester bullet has a soft metal tip that causes rapid expansion and penetration of bullet. Typically used for varminting and hunting light- and medium-size game. BT: boat-tail Rifle bullet with truncated conical shape at base of bullet. Streamlining stabilizes bullet and increases accuracy. BTHP: boat-tail hollow point Same as plain boat-tail but with a hollow point, which generates rapid expansion and penetration. BTSP: boat-tail soft point Like the plain boat-tail but with a soft point to increase penetration and expansion from exposed lead tip.

BRPT: bronze point Bronze insert in tip improves trajectory, velocity and energy transfer at extreme ranges. Tip expands rapidly when driven back through bullet. Excellent design for hunting longrange medium-size game. CC: copper-coated Same as full-metal-jacket. Copper coating prevents bullet deformation in feed mechanism and barrel, reduces misfires and lowers risk of barrel damage. CP: copper-plated Lead bullet dipped in copper; reduces lead fouling and is cheaper than copper coating. CL: Core-Lokt Remington's premier bonded bullet. Retains up to 95% of original weight with maximum penetration and energy transfer. Progressively tapered jacket initiates and controls expansion nearly 2x. Unique design and bonded lead core delivers performance from 50 to 500 yards. ENCAP: encapsulated Totally plated on all sides to decrease environmental lead contamination. Many indoor ranges use this ammunition exclusively to reduce lead clean-up costs. EFMJ: expanding full metal jacket Federal's answer to areas with restrictions on hollow points. A regular full-metal-jacket bullet with front rubber core covered by a copper jacket. When fired into target media, copper jacket collapses along serrations, produces petal-like expansion and delivers energy without over-penetration. EP: Expanding Point Winchester-developed bullet for .25ACP for better stopping power for small calibers. Hollow point with round lead ball inserted into cavity ensures positive feed, increases expansion and transfers energy rapidly. ERBT: Extended-Range Boat-tail Remington bullet that produces long-range accuracy along with superior stopping power required for hunting. FMC: full-metal case Lead core fully enclosed with copper, nickel, brass or steel.

FMJ: full-metal jacket Military round specified by Geneva Convention. Metal surrounds lead or steel core to prevent additional mushrooming of bullet, which may cause inhumane wounding. Usually has lead-exposed base. FMJBT: full-metal-jacket boat-tail Like FMJ but has a boat-tail to reduce turbulence and increase accuracy. FMJE: full-metal-jacket encapsulated Like FMJ but also has covered base and doesn't expose any lead. FPJ: flat-point jacketed FMJ with a flat point. Most .40 S&W and .30-30 Winchester rounds have this design. The .30-30 Winchester has a tubular magazine and uses a flat-point bullet to prevent accidental detonation during recoil, as front round's primer may come in contact with point of round following it. FPPN: Flat Point Penetrator The Flat Point Penetrator was specifically designed to take down big game in Africa. The bullet features a hard lead core that is surrounded by a copper jacket. The bullet is very accurate and produces bone breaking capabilities in one package. FNSP: flat-nose soft-point Similar to the FPJ but has lead-exposed point that expands on impact. Used for hunting. FRAN: frangible Prevents ricochet by breaking apart on contact. Can be made from empty cartridge cases filled with epoxy and compressed bird shot, metal dust or filings. Developed for air marshals to avoid over-penetration and ricochet aboard airplanes. All energy is transferred to the target, making it a devastating defensive bullet. GCK: gas check Metallic cup or disc is attached to bottom of lead-alloy bullet. Decreases gas blow-by, increases velocity and reduces lead fouling. GDHP: Gold Dot hollow point Speer's hollow point bullet with jacket bonded to lead core to prevent separation and control expansion and penetration.

GS: Grand Slam Speer's design for hunting big game. Jacket is 45% bigger at base to prevent rollback and retain bullet's weight. Internal jacket flutes ensure proper expansion. Bullet's core is a ternary (three-part) alloy, which is poured into jacket at 900 degrees F to prevent jacket slippage. HBWC: hollow-base wad cutter Preferred by some target shooters, this flat lead bullet with hollow base punches neat, round holes in paper targets and makes scoring easier. Creates better gas seal to prevent gas blow-by and increase velocity. HSHK: Hydra-Shok Federal's handgun defense bullet. Unique center-post design delivers controlled expansion. Notched jacket transfers energy efficiently and penetrates barriers while retaining stopping power. HP: hollow point Hollow cavity in bullet's nose allows expansion on impact. HPBT: hollow point boat-tail Rifle bullet with a truncated conical shape at base of bullet. Hollow cavity in nose allows expansion on impact. HSP: hollow soft point Exposed lead point and hollow cavity in nose permits expansion on impact. HV: high velocity Ammunition with velocity over 1,200 feet per second. JFP: jacketed flat point Flat lead point and full metal jacket. All .30-30 Winchesters have this bullet design. The .30-30 Winchester has a tubular magazine and uses a flat-point bullet to prevent accidental detonation during recoil, as front round's primer may come in contact with point of round following it. JHC: jacketed hollow cavity Jacketed bullet with hole in tip to promote expansion on impact. JHP: jacketed hollow point Jacketed bullet with hole in tip to promote expansion on impact.

JSP: jacketed soft point Jacketed bullet with hole in tip to promote expansion on impact. L: lead An all-lead bullet. LRN: lead round nose Solid lead bullet with round nose.
