    I just got into guns about a year ago and have asked what the letters on the side of the box mean to a lot of different people. I always get some very generalized answer so I'm coming to you guys yet again. What do they mean and what do I want to feed my little fire breathing monsters :twisted:.

    I bought a .45 compact last Aug. With it I bought some fed. 230 gr. hydra-shok JHP. I heard from some people on here that it was just ok ammo. Last week I picked up a .40 subby. and bought similar ammo for it. Just buying what these guys have. I'm gonna have to start buying on the net or something.

    Both are all black and I LOVE both. Never thought I'd be this hooked. These things are like tattoo's. Once you get one.... well, you know the rest.

    Either way, since I bought my 1st gun I've learned pretty much everything about it and how it works from you guys.

    So thanx again in advance for any info you guys can give.

    FMJ is full metal jacket. This typicall means a round nose or flat nose bullet with a copper jacket. The jacket does not cover the bottom of the bullet (if it did it would be total metal jacket).

    JHP is jacketed hollow point. Think FMJ but with a hollow point in it. This is your typical self defense bullet.

    +P (or +P+) means a higher pressure cartridge. Higher pressure means faster velocities and more energy into your target. Not all guns can shoot high pressure loads.

    IMHO, if your gun will feed it correctly, pick up some federal HST jacketed hollow points (JHP). A lot of times hollow points will not feed correctly in semi auto guns. This is more true with .45 ACP guns. If it doesn't jam, HST is a damn fine cartridge for you.

    [SIZE=+1]Acronyms - Used to Describe Bullet Shape and/or Construction

    Here's a list of the more traditional acronyms used to describe bullet shapes and/or construction:

    BBWC - Bevel-Base WadCutter

    BT - Boat-Tailed

    CB - Cast Bullet

    DEWC - Double Ended WadCutter

    FMJ - Full Metal Jacket

    FP - Flat Point

    HBWC - Hollow-Base WadCutter

    HP - Hollow Point

    JHP - Jacketed Hollow Point

    JSP - Jacketed Soft Point

    LHP - Lead Hollow Point

    LRN - Lead, Round Nose

    LSWC - Lead Semi-WadCutter

    MC - Metal Cased

    MRWC - Mid-Range WadCutter

    PB* - Lead Bullet

    PSP - Pointed Soft Point or Plated Soft Point

    RNL - Round Nosed Lead

    SJHP - Semi-Jacketed Hollow Point

    SJSP - Semi-Jacketed Soft Point

    SP - Soft Point or Spire Point

    SPTZ - Spitzer

    SWC - Semi-WadCutter

    TC - Truncated Cone

    TMJ - like _Totally_ Metal Jacketed, dude

    VLD - Very Low Drag

    WC - WadCutter

    * - Lead is abbreviated Pb from its latin name 'plumbum.' Pb might also be used (on cartridge cases rather than bullets) as an abbreviation for Parabellum.

    J is usually Jacketed. P is usually Point. S might be Soft, Semi, Spire, or Spitzer.

    This is not a complete list, but you get the idea. From here you can cut and paste your favorite bullet shape, like maybe SWCHP (Semi-WadCutter Hollow Point) or JHPBTS (Jacketed Hollow Point Boat-Tailed Spitzer.)

    Bullet and cartridge companies have also introduced some creative new names for bullets in an effort to distinguish their products from those of other companies. These are generally used to describe a particular product, rather than the general bullet construction. For example, Remington's Golden Sabre bullets would rightly be described as JHP (Jacketed Hollow Point), however, they have chosen to label them HPJ (High Performance Jacketed) instead. A partial listing of these fancy
    new acronyms includes:

    HPJ - Remington High Performance Jacketed (Golden Sabre)

    ACC - Remington ACCelerator

    CL or PL - Remington Core-Lokt or Power-Lokt

    XTP - Hornady eXtreme Terminal Performance

    L-C/T - Hornady Lead Combat/Target

    SX - Hornady Super eXplosive

    GDHP - Speer Gold Dot Hollow Point

    STHP - Winchester Silver Tip Hollow Point

    FST - Winchester Fail Safe Talon (Black Talon)

    SXT - Winchester Supreme eXpansion Talon (Black Talon)

    The last one here is also fondly known as:
    EBKDDERSFSCCFRTDACHSIBSDXTMELAWKITNBT

    which stands for: Evil Baby-Killing Death-Dealing
    Emergency-Room-Surgeon-Finger-Shredding Crime-Causing Flesh-Ripping
    Too-Dangerous-for-Average-Citizen Heat-Seeking
    Innocent-Bystander-Search-and-Destroy eXploding Tearing Maiming End-of-
    Life-As-We-Know-It Thermo-Nuclear Black Talon

    which, due to an unfortunate corporate decision, was the name that these
    particular bullets got instead of the name 'Winchester Safety Blossoms'
    suggested by Chris Luchini (rec.guns Tue Nov 23 1993).





    Acronyms - Used in Naming Cartridges

    Cartridge designs are typically given names that are a combination of numerical designations and letters or words. The numbers usually describe some dimension of the bullet or case. The letters and words usually but not always indicate the person, persons, or company which developed the cartridge design. This list decyphers some of the common
    abbreviations and acronyms involved. A list of cartridges that are "commonly" available for revolvers is in Section III.B.1. A list of "commonly" available cartridges for semi-automatic pistols including synonymous cartridge names can be found in Section III.C.1. A list of available cartridges for rifles will appear in Section III.D.1., but was not complete at the time of this writing. Included here are one or two examples of cartridges which use each abbreviation.

    Acronym or abbreviation (Examples)

    ACP - Automatic Colt Pistol (.45 ACP, .32 ACP)

    AE - Action Express (.41 AE, .50 AE)

    BR - Bench Rest Remington (6mm BR, 7mm BR)

    B&D - Bain and Davis (.357/44 B&D)

    G&A - Guns & Ammo Magazine (.40 G&A, .460 G&A)

    H&H - Holland & Holland (.375 H&H)

    H&R - Harrington & Richardson (.32 H&R Mag.)

    IHMSA - International Handgun Metallic Silhouette Assoc.(7mm IHMSA)

    JDJ - J. D. Jones (.375 JDJ)

    JRS - John R. Sundra (7mm JRS)

    LC - Long Colt (.38 LC)

    LR - Long Rifle (.22 LR)

    Mag - Magnum (.357 Mag, .44 Mag)

    mm - millimeter (10mm, 7mm Mag)

    NATO - North Atlantic Treaty Organization (7.62 NATO, 5.56
    NATO)

    Para. (sometimes Pb) - Parabellum (9mm Para.)

    PPC - Pindell-Palmisano Cartridge (.22 PPC, 6mm PPC)

    Rem - Remington (.223 Rem, .35 Rem)

    Ren - Charles Rensing & Jim Rock (.270 Ren)

    RF - RimFire (.22 RF)

    Spl. - Special (.38 Spl. .32 Win Spl.)


    Sprg. - Springfield Armory (.30-06 Sprg.)

    S&H - Sharpe & Hart (7x61 S&H)

    S&W - Smith & Wesson (.40 S&W, .32 S&W)

    STA - Shooting Times Alaskan

    STE - Shooting Times Easterner

    STW - Shooting Times Westerner (7mm STW)

    TCU - Thompson/Center and (Wes) Ugalde (7mm TCU, 6mm TCU)

    TSW - Team Smith & Wesson (.356 TSW)

    Win - Winchester (.308 Win, .32 Win Spl.)

    WMR - Winchester Magnum Rimfire (.22 WMR)

    NOTES

    - 7.62 NATO and .308 Win are equivalent.

    - 5.56 NATO and .223 Remington are equivalent.

    - From a latin expression "si vis pacem, para bellum," meaning, "if you would have peace, prepare for war."

    - 9mm Para., 9mm Luger, 9mm NATO, and 9x19mm all use equivalent
    cases, however, 9mm NATO military ammunition is loaded to
    substantially higher pressures than most commercial varieties.


    - .22 RF usually refers to one or more of: .22 Short, .22 Long, and .22 LR.

    - Wildcat cartridges developed by Shooting Times Magazine/Layne Simpson.


    T


    +P and +P+ Used in Cartridge Names

    Each cartridge for which firearms are chambered has a standard working pressure. Firearms chambered for a given cartridge must be able to withstand the pressure that that cartridge produces. Some modern firearms are significantly "over built", and can tolerate pressures higher than those generated by the cartridge for which they are chambered. The +P and +P+ ratings were developed to take advantage of
    the greater strength built into these guns.

    WARNING! - Ammunition designated as +P or +P+ should not be fired in a gun without the approval of the manufacturer of the gun.

    +P appended to a cartridge name, indicates that the loaded cartridge will generate pressures higher than the industry standard for that cartridge when it is fired.

    +P+ appended to a cartridge name, indicates pressures even greater than those generated by +P designated ammunition will occur when fired.

    +P and +P+ loads for .38 Spl. produce pressures that fall between those of standard .38 Spl and .357 Magnum, therefore, .38 Spl. ammunition designated +P and +P+ can be fired in .357 Magnum revolvers.





    Some Other Acronyms

    Here are some other acronyms that may be encountered:

    DCM - Director of Civilian Marksmanship, see info. in Section X.A.

    GSSF - Glock Sport Shooting Foundation (for Glock owners who don't want to compete with, and risk being beaten by, owners of another brand of gun. :) chuckle...

    IBS - International Benchrest Shooters

    IMR - Improved Military Rifle (Originally, DuPont's name for some of its canister powders.)

    IPSC - International Practical Shooting Confederation, see info. in Section IX.B.

    NBRSA - National Bench Rest Shooters Association

    NRA - National Rifle Association, read about why you should join the NRA.

    NRMA - National Reloading Manufacturers Association

    NSSF - National Shooting Sports Foundation

    SAAMI - Sporting Arms and Ammunition Manufacturers Institute

    USPSA - United States Practical Shooting Association[/SIZE]

    ^^^Holy cow thats a lot of info, thanks for clearing up the bullet info though I was wondering about a lot of those myself. I especially liked learning about the EBKDDERSFSCCFRTDACHSIBSDXTMELAWKITNBT... too bad those never made it to the market ;)

    OK... Here's a stumper for the experts here. I'm over at The Hunting Shack browsing their ammo selections and they have something labeled "JHP UHP" in several different calibers - what the heck is that? I was going to write to them and ask but I figured I'd try here first. Any ideas? Uni-cor? Unicorn???

    :lol:

    My other guess was "ungulate hollow-point" bullets, specifically designed for hunting hooved mammals. But maybe I'm getting too technical? How would the shape/function of the bullet relate to hooves anyway?

    Ungulate - Wikipedia, the free encyclopedia

    :confused:

    Good stuff guys!

    Liv4DaRide, the Hydra-Shok might be old-hat to some, but it's still a 230 gr. JHP and I wouldn't lose any sleep over having them in my own .45 ACP pistol. Are there better? Maybe if you need to shoot through car doors or windshields or other things most of us may never encounter, then there are the bonded 230 gr. JHPs like the Gold Dot, HST, Ranger, etc. As far as what most of us are likely to encounter, penetration after 4 layers of denim, the Hydra-Shok will be more than enough.

    It's kinda' funny that many will debate the legal ramifications of using a handload in a self-defense shooting, but never consider that they may have to explain why they needed to shoot an "aggressor" behind a windshield or car door. ;)

    Lets not forget CE.
    Controlled expansion
    Usually a term to come up more often with rifle cartridges but many pistol rounds fall into this category as well.
    DP: deep penetration, ( fmj, tmj, steel core,etc) military, target
    Re: rapid expansion, ( hollow points and frangibles) self defense, law enforcement
    And then of course CE. Hunting
    All practical cartridges fall into one of these categories.


    "which stands for: Evil baby-killing death-dealing
    emergency-room-surgeon-finger-shredding crime-causing flesh-ripping
    too-dangerous-for-average-citizen heat-seeking
    innocent-bystander-search-and-destroy exploding tearing maiming end-of-
    life-as-we-know-it thermo-nuclear black talon

    which, due to an unfortunate corporate decision, was the name that these
    particular bullets got instead of the name 'winchester safety blossoms'
    suggested by chris luchini (rec.guns tue nov 23 1993)."

    Now thats funny! I used to love hunting with black talons in my 7 mag and then they were banned. Good thing they were only banned by name so winchester just changes the jacket color and name. Voila! Super excellent big game cartridge. I never could figure out why they even banned them for bolt action rifle. When is the last time you heard of a bank get robbed or officer shot by a perpetrator with a bolt action?!
