On a parralell note, My father was telling me a story of when he was in vietnam. A new machinegunner got scared in a firefight and held sown the paddles on the .50 for much longer than he should have. The barrel started curving to the right and it got white hot at the point where the barrel and reciever meet. He said you could see the bullets make white rings as they flew out the barrel. As long as the guy kept fireing he was ok but as soon as he stopped the gun started cooking rounds off and basically fired on its own till they broke the belt. "When the going gets tough, the tough go cyclic!"
My point is we need catosrtophic failures in these machineguns to put some sort of realistic penalty in place for spray and pray tactics using extremely long and unrealistic trigger pulls.
Didn't your daddy learn that saying in Vietnam? I sure did
And if you don't know what "cyclic rate of fire" means: It's the rate (in rounds per minute) at which an MG will fire if you just hold down the trigger.
The first part of your post is correct.
Fire long bursts in an air-cooled MG and the heat will warp the barrel. "Bursts of six" is the way gunners are trained.
I disagree with your last sentence because long bursts will not cause a "catastrophic (or catosrtophic – another US public schools spelling bee winner
Heat just makes the gun very inaccurate. Which is why most machine guns these days have quick change barrels. Even the venerable Ma Deuce recently was modified so you can throw a lever and switch barrels.
For some bizarre and totally incorrect reason, folks who play combat flight sims think heat causes stoppages and jams.
It doesn't. It just messes up the barrel, as you noted.
What causes stoppages and jams (and they are different, a stoppage is a bullet stuck in the barrel while a jam is ruptured casing stuck in the chamber
) is poor quality control in the manufacture and storage and transport of ammunition.
And it doesn't appear anyone in WWI kept track of how often it did that and how often it could be fixed in flight.
Insensitive bastids probably never gave a thought to those of us forced to fly cartoon versions of their airplanes 100 years later.
My personal opinion is jams and stoppages are much, much too frequent in RoF and much, much too easy to clear (one push of a key).Bottom line: Long bursts do not cause jams.
Bad ammo causes jams.
