    Firing full autos continuously

    I once took a class where we used M-16's on full automatic. During the drills where we did go full auto we were told to only fire in two round bursts as that's how you're supposed to used full automatics. When it comes to magazine fed full automatics such as the M-16 you only want to fire in two or three round bursts, you don't want to fire continuously where you go through an entire magazine with one pull of the trigger.

    Now when it comes to belt fed full automatics I do believe you can fire continuously and not have much problems except for the weapon overheating. If the weapon had a cooling system that could do away with the problem with it overheating. So, a belt fed full automatic with a cooling system should be able to be fired continuously without any problems.

    Like the water cooled WW2 MGs.




    But even they were limited in how long they could fire continuously.

    In 1965/1966 in Viet Nam, I manned an M2 (Ma Deuce) 50 BMG with an M-2 Carbine as an initial backup. The M-2 Carbine was replaced with an M-14. In 1970/1971 as an advisor in Viet Nam, I carried an M-16 with a 1911 as a backup. I had bandoliers of loaded magazines.

    We had spare barrels for the M2 50 BMG.

    Yes that would definitely be an example of a weapon that could be fired continuously, to some extent.

    But with modern weapons that have modern cooling systems that use much better coolants than water, you should be able to fire an entire belt of ammo with a single trigger pull.

    Until the fixed position is overrun then your done.

    Reason for the 2 - 3 round burst was control and hitting the target. We had full auto M16 rifles in ROTC but seldom fired full auto. Almost never. Pretty sure those all were replaced with burst select fire in subsequent years. But my experience is dated. Very dated.
    I find supremely ironic that God in his wisdom and grace has given man freedom of choice bounded by 10 simple rules. Man in his finite wisdom has created millions of rules to limit freedom of choice and personal responsibility of man.

    I was just reading a book by Major George C. Nolte, Jr. and he mentions an aluminum case the military was testing. On prolonged firing of a M60 the barrel got so hot that a case ignited "like thermite" and the result was the M60 melting in half! Aluminum melts at 1,220 degrees F, but steel 1,500 degrees F! Interesting.

    That's why the weapon needs a good cooling system.

    Ours got hot on the range. Had to pace the fire.

    When Browning tested his original Model 1917 water cooled machine gun, he linked cloth belts together that allowed the gun to fire continually for 48 minutes straight. And fired over 21,000 rounds. This was accomplished in one long, continuous burst.

    "Consequently, Browning used a second gun that not only duplicated the original trial, but it also fired continuously for 48 minutes and 12 seconds (over 21,000 rounds)."

    Yep, unless you are trying to gain fire superiority in combat engagement, full continuous auto is not good.

    It quickly ruins barrels. Barrel wash is a real thing. Accuracy greatly diminishes.
