I absolutely love the 338 winmag took this guy this year with mine some say they kick a lot but I dont find it to be upsetting by any means I was able to shoot that bear and watch him drop in his tracks and disappear as he fell in the grass through the scope at 280 give or take a yard as I ranged it. I understand both aspects of wanting to hunt with it as well as not so I'm no help there but personally I would build the new stainless rifle and still hunt with the 70. If you end up somewhere salty and super wet take the stainless otherwise use the 70 and down the road if you have kids that want to hunt you can pass it down again and still not be out a 338 because you will have your stainless who knows your kid might want that one instead.
