[QUOTE="Professor Doolittle, post: 2276486, member: 118902"] Any of you guys know a precise way of measuring barrel temperature? We've tried touching the barrel in a consistent place with a thermocouple and we've tried laser thermometers, but both of these are on the outside of the barrel and we have no knowledge of the thermal conductivity of steel. How is heat actually traveling through the barrel and how long does it take? I haven't seen a pro article that addresses this even though barrel temp definitely effects muzzle velocity and if you punch in muzzle velocity differences into a ballistics calculator you see it doesn't take much to add several inches of error to a target 1000 yards away.
