[QUOTE="MajorSpittle, post: 1613871, member: 53101"] Just got home and couldn't find my notes to verify CBTO, but from memory it was 2.683ish with the Hornady OAL gauge. I later found this to be incorrect though when loading Neck sized brass and found I could actually load significantly longer before hitting the lands. COAL was 3.345-3.37, all shot great with the best groups being 3.35ish. I also shot some 178 A-Max with a COAL of 3.37 that had almost identical POI and was just as tight. These were a touch over book max, but velocity was lower and they showed no pressure signs. I could be wrong about being .05" off the lands, I would need to find my notes to be sure as I have been loading for my 270 last week and have all those numbers floating around in my head still.
