There are a couple of words I've heard and read many when discussing
firearms, but I'm still not exactly sure what they actually mean. The
words are:

Magnum

Match / Match-grade

Can you please give me full definations of these terms?

Magnum: A shell / cartridge with greater power than normal such as a 3
inch magnum 12 gauge shell verses the standard 2 � inch.

Match Grade: A step above service grade and / or rack grade. More
accurate then service or rack grade.

Large capacity, the use of the word derives from the Magnum of Champagne.

It refers to stuff held to higher specs and QC standards.

"Magnum" generally describes a cartridge that is based on (similar
design) another, earlier cartridge but is more powerful. It is usually
longer, or in the case of some some rifle cartridges, has a "belt",
but these are mostly for safety reasons to make it harder to
accidentally put the more powerful cartridge in an older gun that was
not designed to handle it, since the sizes and names are similar and
can lead to confusion...

"Match" basically means that something made to a higher precision to
make it more accurate, or that it has been modified to make it more
accurate.

Neither has a globally agreed upon meaning, and both are often used
for marketing purposes when most of us would agree that they are
somewhere between "creative" and "dishonest".

Usually wine is sold in 750 ml bottles but one can purchase 1.5L of wine in
a magnum which means a bigger bottle. The word magnum when referring to
rifle cartridges GENERALLY refers to cartridges with a greater than normal
powder capacity. This also GENERALLY means greater velocity for any given
bullet weight especially those heavier bullets for a given caliber. I mean
GENERALLY as today with the entry of the short/compact magnum series of
cartridges have muddied the waters. Some of the newer short/compact magnums
have neither the case capacity nor the velocity which would be considered
"magnum". However, many companies have found that usurping the magnum title
could help boost sales. In other words magnum has been reduced to a
marketing gimmick by some of the better known firms.

Match or match grade refers to rifles or cartridges manufactured to tighter
tolerances than one would reasonably expect. The intended result is almost
always greater accuracy. Remember most rifles and ammunitions are mass
produced. Rifle and ammunition manufacturers make rifles and ammunitions
looser tolerances so that cartridges and the rifles which chamber them may
be compatible. Tightening the tolerances may negate such compatibility
between the rifle and cartridge.

Match grade bullets are carefully made with very little weight variation,
core to jacket concentricity and attention to shape etc.

Careful attention is paid to chamber /barrel alighment.

Match grade barrels are smoother and made to a tighter tolerance and
carefully crowned.

Match grade rifle chambers are generally tighter (within lower minimum 10%
or better) .

Hopefully this helps.

Smith and Wesson first applied this word to it's .357 cartridge,
introduced in 1935, as a sales gimmick, but didn't, or couldn't, get a
copyright for it as applied to cartridges, so lots of other
manufactures and wildcatters used it for the same reason. It's
supposed to mean "more powerful". It doesn't really mean anything,
it's just a name.

#Match / Match-grade

Intended for some form of competition use. The folks who use it would
like you to think it means their products are made with more
precision. Another sales gimmick. Some times it's true, sometimes it
isn't. More often the latter.

As others have noted they have some meaning related to firearms, but
they are primarily marketing oriented. They have no legal meaning.
Just because a cartridge is called Magnum or ammo or a barrel is called
Match or Match grade is no guarantee of performance. For example a
222 Remington Magnum is a much smaller cartridge than a 22-250 or a 220
Swift. It's little larger than a 222 Remington. Likewise "Match Grade"
is more of an indication that ammo is intended to used for target
shooting rather than hunting but that doesn't mean it's more accurate.
A "match grade" chamber usually means its cut to the small side of
SAAMI specifications. It may or may not be more accurate than a
standard chamber. There really are no formal definitions set by some
governing body, only common usage.

I think it often is meant to convey the idea that it's derived from
another cartridge, with higher pressure than that other cartridge is
spec-ed at, and so the case is made slightly longer to prevent the new
cartridge from being inserted into a gun designed for the less-powerful
cartridge. That feature is often very useful and convenient, when it
allows a gun designed for the more powerful cartridge to also fire the
shorter, less-powerful cartridge (e.g., for target practice).

Examples are .357-magnum vs .38-special, and 44-magnum vs 44-special.
But sometimes usage hasn't adhered to that idea: I think the 41-magnum
wasn't derived from any lower-powered cartridge currently in existence.

Actually nothing to do with ammunition. The way I heard it, S&W
developed the round before they named it, so for publicity reasons
someone thought of it being compared to a magnum of champagne, as in
bigger than a standard bottle. It was strictly a publicity stunt that
payed off in dividends.
