A Mauser will never be light weight, will never be competitively accurate, and will never take bratwurst-sized magnums, unless you want to drop five figures for a double-bridged Brevex. It was designed for the 7X57, and anything really far from that is a stretch. Build it within its strengths, and a safari rifle is perfect. Not much brush to scratch that AAA stock, shots generally under 200 yards, and somebody else carries it for you. No matter what you do to it, it's a 120 year old military design. What it is, really, is a piece of mechanical art, built when quality was never second to economy. For that reason, things that usually look stupid on a modern rifle, like half-octagon barrels, intricate express sights and double triggers, just work. It will never be modern, or state of the art, and most attempts to make it so are abominations. Like a tactical Velcro band on a prewar Rolex.
