I have a .308 that needs a new barrel soon. It is a savage 10fp. I was leaning towards rebarreling it to a 7mm-08 until I read a little about the straight .284 win. I really want this now for under 800 yard work but I dont know what the mehcanics are? Is the bolt face of the .284 and .308 the same allowing me to use the same action with a new barrel? Is the difference between the 7mm-08 and the .284 as good as I read here: 7mm Cartridge Guide thanks guys, Newbie!
