With .210 fb I'm at 3.049" case overall length with the Berger 180 vld. With my Lone Peak Fuzion build I'm using Hawkins medium bottom metal in an M5 hinge floor plate configuration internal box length is 3.200". If a person really wanted a short action, I also built a 6.5 saum with a .220 fb on a Lone Peak Fuzion short action. I'm using Unknown Munitions short action detachable bottom metal and magazine set up. Their short mag XL magazine is 3.150" inside length. I had to do a slight modification to the action but it worked out great.
