[QUOTE="davkrat, post: 1084737, member: 6452"] Yeah I understand what the abbreviation ES stands for. In shooting/reloading I have never heard anyone refer to they extreme spread when measuring a group. I don't see any purpose in the extreme spread of a group other allowing a comparison to someone else's group which was measured center to center or inside to inside. But none of that means anything. Measuring and hopefully reducing extreme spread of velocity on the other hand is significant when shooting long range. To me the velocity is the only ES that matters. Referring to the ES of a group is nonsense, it doesn't tell you anything more or less than measuring the CTC of a group. [/QUOTE]
