I just had a 7 SAUM built on a Tac-30 short action. I was planning on shooting a 168 or 180 Berger. When I checked the oal to touch rifling its a full .1 (tenth) or should I say 100 thousands longer than box mag. I don't think you can get a berger VLD to jump that far and shoot. Box mag will go about 2.83 and the 168 goes 2.915!!!! Options??
