I currently have a sendero chambered in 300 rum. I have officially shot the barrel out of it and I am going to be re-barreling the rifle for the 338 edge cart. I am looking at Bartlein barrels and I am having a tough time deciding what contour I should go with. I plan on having the barrel 28 inches long (without the brake) and one of my goals is to have a gun that finishes around 10.5 to 12 lbs before the scope. (I do need to pack the rifle in a couple of miles.) The two contours I am looking at are the Rem/sendero contour or the med. palma. I have not heard of very many people using bartlein barrels for the 338 edge but I believe they are top notch barrels. Any advice would be great.
