[QUOTE="Lonewolf74, post: 1366701, member: 96274"] I've been thinking the same thing I would think 78 grains would be hauling. It's a 26" factory Remington 5R barrel. I didn't crono the 79 grain charge cus I was just doing a quick OCW before season, but 78 grains is consistently around 2810. I think my chamber is on the large side, I had the action trued and chamber and throat recut to match a dummy round I made with the 215. Touching lands is at 2.930 base to ogive. However the chamber body seems big I'm using the .010 (tallest) Redding competition shell holder and that bumps the shoulder back .002-.003 from fired size. So if I understand things right my chamber is roughly. 010 oversized which may be causing lower pressures and velocity and I've been able to load at the high end with zero pressure sign? [/QUOTE]
