no flames , not even anything of the sort.

you are exackly right. in the real world fluting wont make that much difrence.

but i would be curious to see how much extra surface area a fluted 920 barrel had over a reg tube in the same diamter.

id measuer the surface area of both and i bet the fluted has a quite noticably larger surface to dissapate heat. say you flute 920 barrel in 20cal with deep flutes. then you might have noticably cooler barrel, but it might not be the case in the real world we live in.

also flutes reduce barrel weight. wich is a plus for me. ive only got one fluted barrel and its on my 10/22. got it for mostly looks but its also noticably lighter than unfluted barrels.
