Ackleyman, as a point of reference, what would it take to get the barrel to 800 degrees in something like one of the wssm's? I am thinking that you would have to really be trying to burn up a barrel to get it anywhere close to that.
25 years and pounds ago I was in the service(USMC). I can remember that the M60 barrels would be so hot after 200 rounds that if you touched them your skin would be left on the barrel. I am guessing that that was not even 800 degrees?
EDIT: I did a google search and came up with this:
Doesn’t really matter what the emitter is…stainless steel, cast iron, tungsten in your light bulb, the temps are about the same for a given color. Generally accepted colors/temps are:
C F Color
400 752 Red heat, visible in the dark
474 885 Red heat, visible in the twilight
525 975 Red heat, visible in the daylight
581 1077 Red heat, visible in the sunlight
700 1292 Dark red
800 1472 Dull cherry-red
900 1652 Cherry-red
1000 1832 Bright cherry-red
1100 2012 Orange-red
C= Centigrade
F= Farenheit
Your skin will burn at 130 to 140 degrees. I think we are very safely out of the 800 degree danger zone.
