I am thinking of making a rifle. Looking at using a BCM 18" SS barrel. I am thinking of having the barrel dimpled or fluted to drop the weight some, as I plan to use the rifle in the carbine roll.

Do yall know how much weight reduction I can get by dimpling the barrel or having it fluted? I would think with the dimpling the barrel would cool much faster because of the added surface area. is that correct?

thanks.
