UMC stands for Union Metallic Cartridge

And the MC is for Metallic Case which is Remington's way of describing a Full Metal Jacketed Bullet.

GR. stands for grain.. .BTW

 

[RicInOR]

what the 'ell is a grain? why don't we use grams, or oz?

Spoiler: metric grain

the smallest unit of weight in the avoirdupois, Troy, and apothecaries' systems, based on the average weight of a grain of wheat: in the avoirdupois system it equals 1⁄7000 of a pound, and in the Troy and apothecaries' systems it equals 1⁄5760 of a pound. 1 grain is equal to 0.0648 gram
. Abbreviation: gr
11. Also called: metric grain
a metric unit of weight used for pearls or diamonds, equal to 50 milligrams or one quarter of a carat

1) I always thought MC meant Motorcycle Club, as in "Spawn of Satan M/C."
2) 1 grain = 1/7000th lb. 1 oz. avoirdupois = 437.5 gr 1 oz. Troy = 583.33 gr.

 

[Stomper]

Math is so..... sexy.

avoirdupois

I can't even pronounce that!

Powder charges for muskets and shotguns used to be measured in drams, ie., 2 1/2 drams = service load for the P53 Enfield rifles musket used by both sides in the WoNA. One dram = 27.3438gr. Shot loads for shotguns were measured in ounces.

More precise measurements were always measured in grains, for instance, apothecaries used grains in making up their potions. They also used minims for liquid measures.

Grams are metric, which is why you don't use them much in the USA.

Before the use of decimal fractions came into general everyday measurements, it would have been a real PITA to have measured your bullet weight and powder loads in fraction of ounces. One ounce = 437.5gr, so a .44cal ball, at ca. 145gr, would have weighed 1/3rd of an ounce. Difficult to measure when you are measuring most things in 1/2, 1/4, 1/8, 1/16, 1/32 etc.....

 

[tac]

That term derives from an Anglo-French phrase meaning "goods of weight." Today, "avoirdupois" most commonly refers to the system of weight measurement used for general merchandise, in most English-speaking countries that have not 'metricised', in which the pound (lb) is equal to 16 ounces (oz), the ounce 16 drams, and the dram 27.344 grains (gr).

I did a quick Google search and the only hits for Remington MC meaning metal case were 3rd party ammo sites that were assuming MC means metal case. I haven't found anything from Big Green, themselves that says definitively what MC means. I still vote for Metal Clad.
