I've been thinking about replacing the barrel on my Ruger M77 7mm Rem. Mag. I really like the carbon barrels, but I have heard that they don't perform as well as advertised. Has anyone had any experience with them. I think Christensen and ABS are the only companies with them. Or I was thinking about putting a medium/heavy steel barrel and fluting it to save a little weight. The gun is mainly used for deer hunting.

Thanks
