I've got a 308 that I think is a mauser m12. Several of us here bought them pretty cheap from some place on the east coast a few years ago. It has a fluted 22" or so shorter barrel. I'd firgot about it until the other day I was looking for one of my sauers to finally get it to the range and pulled out the mauser. It looks like a decent rifle too so I'm going to put a scope on it and see how it likes my old 308 loads of 155 scenars over varget.
