Your machine guns in use in 2010 were still developed between the 1950s and 1980s, generally.
A gas operated machine gun might fire anywhere from 500 - 1200 rounds per minute, depending on type. Weapons such as the M-134 Minigun can fire between 3000 - 6000 rounds per minute.
A typical box of linked rounds will contain a single 100 round belt. As many of these can be linked together as required.
As fast as they could in World War II or Korea, though some could fire faster than others. The Browning was medium fast, the Lewis and the Vickers a bit faster, though the Germans had the fastest firing machine guns of all. I don't remember the specific RPM for each gun.
About 650 rounds per minute. You will use up an entire 30-round magazine in just a few seconds of constant trigger pull. That's why M16A2 has only single shot, and 3 round burst switch.
The M-134D and M-134DT fires 50 rounds every second, or about 3,000 rounds per minute. Meaning the six barrels rotate up to 1112 RPM in half a second.
The death total from WWI was estematied to be around 8,528,831 machineguns were about 20%
450 - 650
About 600 rounds per minute on full auto.
720 rounds a minute approximately
The M134 Minigun can fire anywhere from 2,000 to 6,000 rounds per minute. It is a six-barreled machine gun which uses the Gatling-gun style of shooting.
about 500 rounds(bullets) per minute
Anywhere from 400 to 1200 rounds per minute. Some Gatling guns can fire 6000 a minute, although they may not be considered TRUE machine guns.
16 thousand rounds.

As many as you want - assuming you reload. The barrel may well suffer a bit after about 2,000 rounds but it will continue to fire for many more thousands after that. A standard magazine of 10mm rounds carries 15 rounds but that can be lowered as an "optional" extra to 10 rounds - if you want to.
30 rounds = stick mags, 45-70 rounds = drum mags
12-20 rounds depending on caliber and magazine.
anywhere between 3.2 and 12 on a newer machine gun. WW2 weapons such as Browning M3 "grease gun" and Thompson submachine gun could fire at a rate of 5 to 12.5 rounds per Second. The German medium machine gun, MG42, had a rate of 25 rounds per second. The modern US M-60 evloved from this gun. Later guns such as AK-47 and M-16 could fire from 12 to 15 rounds per second.
