While posting about various cartridges in the revolver thread at OT it occured to me that some folks might have no clue what 'FMJ' or 'JHP' means or how they differ amongst others. So a quick search for said terms came up with a reference I found at the Cheaper Than Dirt forum.
I'm going to repost here what 'RendonRedneck' compiled an age ago that is very complete and should more than answer anyones question toward what do those alpha code conventions mean at the end of cartridge names.

Here are a few more...

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.

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 long-range medium-size game.

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.

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.

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 birdshot, 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.

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.

JHC: jacketed hollow cavity
Jacketed bullet with hole in tip to promote expansion on impact.

MK: MatchKing
Made to exact tolerances by Sierra. Delivers record-breaking accuracy at long ranges.

MOLY: moly-coated
Bullet is coated with molybdenum disulfide to reduce friction and increase velocity.

NBT: Nosler Ballistic Tip
Nosler developed this bullet with a polycarbonate tip that protects the bullet from damage in the magazine resulting from recoil. The tip also stabilizes the bullet for long-range shooting and insures reliable expansion when the bullet hits its target.

NP: Nosler Partition
Has two lead cores separated by bullet jacket. Top part of jacket is thin and promotes expansion of bullet. Bottom part of bullet has thicker jacket that retains bullet’s weight, stops fragmentation and increases penetration.

PEP: Positive Expanding Point
Specially designed by Winchester for extreme accuracy and maximum impact on varmints and medium-size game.

PG: Partition Gold
Winchester's proprietary design delivers expansion and penetration on medium- and large-size game at wide range of impact velocities. Rear core is hard lead alloy, locked in place with a heel crimp to prevent core slippage and maximize penetration. Patented steel cup reinforces prevents core distortion at high-impact velocities.

PL: Power-Lokt
Remington's revolutionary varmint and small-game bullet produces benchrest-level accuracy. Copper jacket is electrolytically bonded to lead core, producing near-perfect concentricity and gyroscopic balance, once available only in custom-made match bullets. Exceptional sub-minute-of-angle accuracy for small game at extreme ranges.

PP: Power-Point
Jacketed soft nose from Winchester delivers maximum energy on impact. Notches around jacket's mouth improve upset and ensure uniform, rapid expansion.

PSP & PTDSP: pointed soft point
Pointed bullet retains velocity over long ranges. Soft nose initiates rapid bullet expansion. Jacket and core toughness vary according to caliber and weight of bullet.

PTHP: Platinum-Tipped Hollow Point
A Winchester design for handgun hunters. Immediately transfers bullet's energy into target. Delivers penetration, expansion and accuracy.

PWC: pointed wadcutter
Lubricated solid lead with pointed nose. Formed by swaging process with sharp shoulder for clean hole-punching in paper targets. Good choice for target practice or general shooting.

SBK: Sierra BlitzKing
Used for varmint hunting; has plastic tip inserted into bullet cavity, which expands on impact and delivers high ballistic coefficient.

SFS: Supreme Fail Safe
Hollow point bullet with lead core and steel insert. Delivers controlled expansion, deeper penetration and bullet weight retention.

SLD: solid
Usually made from copper, bronze or brass alloy - but no lead. Designed for deep penetration in thick-skinned animals.

SMP: semi-pointed
Same penetration as a round nose with better trajectory, higher velocity and energy transfer, better expansion control and deeper penetration than a hollow point. At close range, usually offers better penetration and more controlled expansion. Excellent accuracy potential and often used for short- to medium-range hunting.

SPCL: soft point Core-Lokt
Locks progressively heavier jacketed mid-section to lead core, preventing separation but allowing maximum energy transfer. Stays together on impact, expands in a controlled manner and mushrooms uniformly to nearly twice the original diameter.

SPT: spitzer
Pointed bullet normally used in modern military rifles.

SST: Super Shock Tipped
Hornady's design incorporates a pointed polymer tip that improves ballistic coefficient and increases velocity, accuracy and downrange power. Specially designed jacket grips and controls expanding core, allowing maximum expansion while retaining mass and momentum.

SXT: Supreme Expansion Technology
Winchester's personal protection bullet. Designed with reverse tapered jacket, has uniform expansion, greater accuracy and reliable firearm functioning.

TAP: Tactical Application Police
Designed by Hornady specifically for law enforcement. Heavier bullet weight and polymer tip provide rapid expansion and excellent barrier penetration (without over-penetration).

TC: truncated cone
Similar to an inverted cone, but with the top chopped off. Used in defense applications where penetration through materials might be necessary. Ensures extremely reliable feeding.

TCHP: truncated cone hollow point
Same as truncated cone but with a hole in top to promote expansion in target.

TCSB: truncated cone solid bullet
Designed for penetration. Inverted cone aids in feeding, while pointed solid bullet drives deep into target.

TMJ: total metal jacket
Same as full metal jacket, except base is also jacketed.

TMWC: target-master wadcutter
Wadcutter bullets made to highest tolerances to achieve best accuracy possible.

V-Max: Varmint Express ballistic tip
Hornady’s ballistic-tip varmint bullet has a polymer insert that aids in rapid expansion once bullet hits target.

XTP: Extreme Terminal Performance
Hornady bullet designed for controlled expansion at wide range of handgun velocities. Bullet's jacket and core expansion rates are the same, reducing separation and increasing trauma in target.
