Acronyms

Mal H, I think MAP (max. avg. pressure) is very important and should be added. There's nothing statistically wrong with it. But it may be emotionally wrong with you. Besides, it's an expression used in SAAMI specs and tabulated data, so it's factually correct. If MAP is too specific and must be explained in the context of any discussion using it, is there a staff member designated to monitor all the threads in this forum to ensure that requirement's followed?

SAAMI specs on page ten of http://www.saami.org/specifications_and_information/publications/download/206.pdf clearly states the importance of doing it.

There's a few shooting sports and industry terms that my feelings about them say they're wrong, too, but such is life. I'm willing to make compromises about their use for the benefit of the masses who think they're great.

SD in addition to being Sectional Density, could also be Self Defense.
I think we're missing a large number of various bullet designs. I saw RN, but not FN until I noticed it was tacked onto and hidden at the back of the first FN definition. SP can be Soft Point, Spirepoint or Spitzer all. There's a list Here at the bottom of this wiki page that covers quite a few.
 
Then there is 'the length of the case from the shoulder/datum to the head of the case. That can not be head space because SAAMI says the case does not have head space.

and

then there is the length of the chamber from the shoulder/datum to the bolt face.

Then there is 'case length' problem, the case has three lengths, one is the case length from the mouth of the case to the head of the case, another is the length of the case from the shoulder/datum to the case head the other is the length of the case from the shoulder/datum to the mouth of the case.

If you simply shorten the word or chop half of it off, that's an abbreviation.
gr, cal, dia, fps, mag, bbl, adj, DA/SA, DAO, FMJ, JHP, etc.
These are abbreviations.

fps, DA/SA, DAO, FMJ, JHP are clearly acronyms. Each letter stands for a word. That's why OAL is common but is not a valid acronym per se. "Overall" is one word. COL instead would be the acronym to make sense. OL on the other hand is awkward as being too brief.
 
Jeff2131 and Real Gun - this thread isn't intended to be a debate of what the definition of acronym is or what it isn't. That debate ended with the first paragraph in my post #9.

COTUS, SCOTUS (and POTUS) added
GCA is already in the firearms terms list
 
I saw GCA, and NFA, but not FOPA. The red-headed stepchild of gun control that actually threw us a "travelling" bone.

Edit to Add

SA can all be Semi-Automatic,
FA Fully Automatic, SF Select Fire,
SAO Single Action Only (especially common on 1911's and clones)
DAO Double Action Only (common for law enforcement contract suppliers)
SA/DA Can operate in either Single Action or Double Action mode (best example- many revolvers)

WWB - Winchester White Box

When I saw "AE" on the list my first thought was "American Eagle" but I don't know that anyone would use it as a acronym or not.

At the top of the list shouldn't it be:
AA - Accurate Arms - modern gun powder manufacturer

I suggest modifying the definition of Ogive to read -

Ogive - the curved forward portion of a bullet. The radius of the ogive is usually expressed in multiples or fractions of the caliber. Pronounced "Oh-jive".
 
Added FOPA, FA, SAO
Added WWB
Refined definition of AE (added American Eagle and "angle eject" which is what I think of when I see the term, as in a modern Win. 1894)
Refined definition of AA
Added WBY
Refined definition of ogive
 
You are correct Bart. Many initializations have multiple meanings generally determined by context. I've not seen many (any?) threads here at TFL discussing anti-aircraft guns I have seen many threads discussing Accurate Arms powder.
 
Im very aware that this thread was not intended to be a debate, im the OP. I simply wanted to allow alot of our new reloaders to be able to identify what these acronyms are that are used on a daily basis when people post and reply. Im also not in concurrence with "the debate has ended in my post #9" you are only partially correct. Sevens listed acronyms correctly, however....gr. bbl. Adj. Etc....are not "initializations. The ARE in fact abbreviations. And grammatically speaking, must end with a period to signify that they are so. "Initializations" is a term used regarding computers; meaning to boot or start a set of calculations. Im assuming you MEANT to say "initials" which are slightly different than acronyms in that intials are the first letters of ones name, seperated by periods. Continuing the "debate" is not my intent but if we are ending what was but a brief debate, we should atleast end it with accurate information so that those who have read, followed, and commented may benefit from learning that accurate information thus they be more likely to use those terms accurately in the future.
