It will depend on the design and caliber of the firearm. Basically a semi auto can fire as fast as you can pull the trigger (until the magazine is empty- and magazine size varies from 5 to 30 or more rounds). However, that is not aimed, accurate fire- you would be unlikely to hit much of anything. Aimed fire would be a maximum of about 15 rounds per minute. ACCURATE aimed fire. less than that- about 10 a minute. There have been world record holders (such as Bob Munden, who passed away last week) who could accurately fire 6 shots so fast they sounded like one- but those are very rare people. PS- Bob Munden, fastest man with a gun in the world- used a revolver, not a semi-auto.
that would depend on number of rounds being fired. Lets say 10 rounds. I would estimate 10 rounds could be gotten off in about 7 to 8 seconds..................
16 thousand rounds.

Yes, Metal Storm is a scariest weapon. It have 36 barrels and can really fire up to 1 million rounds per minute. Metal Storm can also rip missiles to shreds. It is the World's fastest and the deadliest automatic machine gun never seen on the battlefield. Metal Storm is the most powerful automatic gun in the World and it can fire 16 thousand rounds in 1 second.
Search the term "metalstorm". It is theoretically capable of incredibly high rates of fire- hundreds of thousands of rounds per minute. Short of that, the powered gatling guns can reach (briefly) a rate of fire of about 6,000 rounds per minute.
The original AK-47 had a cyclic rate of fire of 700 rounds per minute. The "modernized" AKM (manufactured from 1959 onwards) had a cyclic rate of fire of 600 rounds per minute. Cyclic rate of fire meaning that, if you had a magazine with such a capacity loaded, and you just held down the trigger, and you could fire off as many rounds without the weapon overheating and becoming defective.
The BAR has a selective fire switch, and could be set to either 300 rpm (5 per second) or 500 rpm (8.333... per second). Neither figure is really accurate though as it was fed by 20 round box magazines. And a good BAR man fired in short bursts. The recoil of the .30-06 rounds would throw off the aim after a few rounds, and tend to overheat the weapon.
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 "Potato Digger" was not the slowest rate of fire weapon. The French Chauchat machine gun fired 240 rounds per minute
The early Thompson sub-machine gun fired at up to 1200 rounds per minute, which translates into 20 rounds per second. Later versions fired at 600-720 rounds per minute, giving a rate of 10-12 rounds per second.
600 rounds per minute, (10 bullets in a second)
There is a broad range of ROF (Rate of Fire). It can be anywhere from a crazy slow 3 rounds per second (some off-brand guns) all the way up to 100 rounds per second (Echo 1 M134). These are the ends of the scale, while most guns fire 10-20 rounds per second on fully automatic.
