On a Remington 700 ADL/BDL in 7mm Rem. mag. what is the outside diameter of this barrel at the muzzel and what barrel contour name/number is this barrel? Would this be considered a #4 Magnum Sporter contour? I'm looking to put a barrel on a Sako A5 action, probably 25-06, and would like to be able to take this rifle hunting and would like something slightly heavier than the contour used on a Rem. 700 in 7mag.. I'm considering a #5 Lightweight Varmint that would add a little more beef to the barrel yet still be light enough to carry/walk. Any suggestions, all advice is appreciated. Thanks.
