The Type 92 firing a 11.3 g (about 175 gr) bullet at 10 rounds per second gives a mass throw of about 0.12 kg/s. The Type 100, firing a very slightly heavier bullet (12 g, 190 gr) at 36 rounds per second throws 0.44 kg/s. I suspect your values are for one minute of firing time.Japanese Navy Type 92 flex threw 6.36 kg of mass in 1 second of fire while the Japanese Army Type 100 threw 23.763 kg of mass in 1 second of fire, for a ratio of 3.74 to 1 or nearly 4 times the energy. One did 600 rpm and one did 2,200 rpm
In the 50-cal / 12.7 mm class, the Browning M2 threw 32.48 kg in 1 second
WHOA... Taking the upper rate of fire: 880 rpm that is a per second rate of 880 / 60 = 15 rounds per second.Browning did 850 - 880 rpm
...
If we go by rate of fire then we have the roughly 400-500rpm guns, basically the Oerlikons. by who ever used them, and the early Japanese army guns Followed by the 600rpm Hispano, then we have the 700-850 rpm MG 151/20, the Russian guns and the Japanese army Ho-5 gun. ...
I think they were a variety of Mauser cartridge.Were the IJN 7.7MM guns actually firing the same as.303 British ammo? .303 British is also known as 7.7MM, at least according to the packages I have.
I think they were a variety of Mauser cartridge.
The Japanese used an amazing variety of guns and ammo and really make a thread for "basics" complicated
The Japanese Navy used the British .303 round in the Lewis copy pictured above. They also used it in their copy/version of the Vickers gun.

Helping to confuse things the Japanese Army used their 7.7x58SR cartridge in their version of the same Vickers gun.
However both the Army and Navy used the German 7.9mm cartridge in their copies of the German MG 15 which they used in the rear seats of some two/three seat planes. Army also used the 7.9mm in that twin barreled gun pictured earlier.
Japanese navy also used a copy of the German 13mm MG 131 but changed the primer to percussion instead of electric like the German guns.
