Trying to get my learn on, specifically for a semiauto AR pattern .308 or 6.5CM rifle. BUT also interested in info pertaining to bolt guns.
Fluted vs non fluted barrels? What mission drives that decision train, or do they not make much of a difference?
What I *think* I know:
Fluted can be lighter weight for the same length and style barrel.
Fluted will heat up faster than a standard barrel of the same outside diameter. Fluted will also cool faster than a standard barrel of the same outside diameter (due to the thinner metal? Or the increased surface area like radiator fins to shed heat).
Standard is stiffer than fluted given the same length and outside diameter .
SCHOOL me, debunk or confirm what I think I know? What's the decision making process for this interesting barrel feature?
