[QUOTE="KSAv8r, post: 2274267, member: 86098"] I find long range and benchrest are two different things and are tuned slightly different because the chamber dimensions are more precise with BR. The smallest ES/SD are what you are initially looking for. There are usually two nodes that will show small ES/SD. Choose the node with the highest speed as long as you don’t see any pressure signs. I also start with the factory recommended CBTO measurement for seating depth and fine tune from there. An ES/SD greater than a single digit really starts to show up when you get past 800 yards has been my experience depending on the caliber and bullet choice. This is especially true in the vertical since the horizontal has more to do with reading the wind. If you have a double digit ES/SD it becomes a crap shoot trying to guess both the vertical and horizontal dope to come up with a shooting solution. [/QUOTE]
