rule of thumb:

cannons- explosive shell

machine guns- rounds

no its size
20mm and above = cannon, mostly.

So if I made a weapon that was a large copy of a browning machine gun, and it's ammo was larger than 20mm in diameter, it's not a machine gun any more, it's a cannon? http://ubbxforums.ubi.com/images/smiley/16x16_smiley-wink.gif

I beleive you'll find that actually, a cannon does not fire rounds, while a machine gun does.

Yes Chuck_Older, gun with caliber 20mm or more is cannon. Shkas 7mm was enlarged to 20 mm and became shvak cannon.

I have never heard of this 20mm distinction between cannons and machine guns. In my experience, the term "cannon" meant guns that fired explosive shells, where as "machine guns" fired solid pieces of metal.

While the ShVAK may be based on the ShKAS, the shVAK does in fact fire explosive rounds:

Likewise, the Japanese Ho-5 20mm cannon was essentially an upscaled Browning M2 .50 cal MG. Saw it at the Udvar-Hazy Center, and it did look just like a big American .50.

After the 7mm machine gun was changed to 20mm, was that the only difference?

Or did the 20mm cannon now fire explosive ammunition, as well? The deciding factor here is, again, the ammunition. The 20mm weapon did not fire a round, it fired a shell.

a heavy machine gun(hmg) is generaly considered to be between 12.7mm-15mm auto cannon is generaly considered to be 20mm with seperate driving bands instead of jacketed bullets

So you are saying the auto cannon is a weapon which generally does not fire rounds?

One last thought before I log off-

If a cannon is a larger calibre machine gun, why was a distinction made in the first place? Why call it anything but a machine gun?

just simple.....like middle-bus or bus or taxi,train.large vehicle can carry more people. cannon fire large and more powerful bullets than machine gun.
normal mean large than 15mm is call it cannon.

how about tanks.....tank's gun shell some is solid shell,like AP round.it will not explosive.
so not mean round or explosive shell.normal meaning is sides of gun.below 15mm call gun,more than 15mm call cannon.

I said 'general rule of thumb'.
A cannon can fire solid shot. But it does not fire a round. "Bullet" does not mean 'any type of solid projectile', as far as I know.

tenmmike-

you'd know:
Can a cannon fire a bullet? Or is every bit of cannon ammo a shell?
I think you've touched on the answer already, with cannons firing something other than jacketed bullets.

Also: is there a particlular way a machine gun barrel rifled as opposed to a cannon's?

I still stand fast: the difference is the type of ammunition
