The Browning M1919 can keep firing until the barrel overheats. It depends on how long the bandolier is, since it's fed that way. If overheated, it can't shoot and the barrel needs to be replaced.
16 thousand rounds.

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 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.
4200 rds/min = 70 rds/sec.
ABOUT 10. The rate of fire is 6oo rounds per minute.
65 rounds a second and as many as 500 rounds in a burst - there is no "per minute"
In full auto mode, rate of fire is between 11 and 15 rounds per second- HOWEVER- that is not the actual rate of fire. The M4 has a "triburst" selector- pull trigger, fires 3 shots, stops. Pull trigger again, 3 more shots. Actual rate is about 5-6 shots a second. The magazine only holds 30 rounds, so you will have to stop and change magazines.
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.
Gatling gun rates of fire depend on caliber, number of barrels and whether electric or hand powered.
12-20 rounds depending on caliber and magazine.
30 rounds = stick mags, 45-70 rounds = drum mags
