[QUOTE="MudRunner2005, post: 1457491, member: 12995"] Alright, my dummy round is made... This bullet is an absolute monster! I can't wait to see a hunting version! Combined with the power and speed of the .25-06 AI, deer to 1,000 yards should be possible. .25-06 AI 40º Shoulder... My measurements I get are are 3.391" COAL, and 2.703" from base-to-ogive. These measurements put the boat tail as the only thing hanging into the case, so it utilizes nearly 100% of the case's capacity, and the neck's length for a full grip on the bearing surface. This COAL will also allow you to seat the bullets as long as you need, and still have plenty of room in a Remington 700 long action. If I was to spec out a reamer, I would make the lands engagement at 2.718". That way at the current COAL, you are sitting exactly .015" off the lands, giving you the best chance for accuracy, and your off the lands far enough to avoid pressure spikes. Here's a picture...
