That is... until it happens to youAlmost nothing funnier than seeing someone on the line dancing around with a piece of hot brass on their neck...![]()
Oniak,
A while back I experimented with a barrel light mount and recorded temps with an IR thermometer at diff locations, temp test. The barrel reached 200-300+ deg F, and the handguards reached 100-120+ deg F (firing 300 rounds in 45 mins). This may/may not help...
Small Arms Review did an article in July 06 concerning Socom's complaints of barrel failures;
I don't know if this is what you are looking for.The first major investigation found the issue regarding blown barrels was clearly due to excessive operation beyond what the carbine was designed........
The barrels would reach their transformation temperature that is between 1,100 and 1,375 degrees. At these temperatures the barrel becomes soft and loses its heat-treating. Structrual failure is just a matter of time. According to Rock Island's testing, to get the barrel to this temperature you would have to fire 540 to 596 rounds within 3 to 3 1/2 minutes.
can get above 451 degrees in three magazines or less... we used to light cigarettes off 'em.
