I got a Remington 7mm Mag Sendero rifle, few years old but everything is still in fantastic shape except for the inside of the barrel. Its just about burned out... So I have been tossing around the idea of chambering the rifle in the 338 caliber and I keep going back and forth between the lapua and RUM case. but I think I have just about settled on the RUM due to brass cost and just easier to built it on my current action. Now the purpose of the rifle being built will be long range hunting. Hence why I joined this site... I would say maximum range would be 1000 yrds on hunting targets. Now I wouldn't mind the rifle being a little more on the heavy side. Say 10-13lbs loaded weght with the scope, that about where it sitting right now with the Konus M30 25x scope installed in Warne rings. So what kind of barrel would a professional hunter recommend? Im thinking something in a heavy profile in the range of 26", preferably with a removeable muzzle break attached so the old lady can shoot it too and it not kill her. I currently have a break installed on it and she loves shooting it with the break installed, but nearly stared a hole into my soul when I convinced her to shoot it without it.
