Good info. Thank you. I didn't realize that barrels reach 1200 degrees under this schedule. It just looked to me that 120 rounds of mixed firing with 10 min break in between and a full cool down after 240 rounds wasn't too bad.
If I recall the same Mil-B-11595E steel is used in many mil barrels including M240/M249 which would experience a more intense firing schedule.
I'm just confused at this point and trying to put two and two together. Wouldn't that imply that M240/M249 wear out barrels significantly faster under a full auto schedule than M16/M4?
