[QUOTE="Whitesheep, post: 1097560, member: 26409"] [b]Measure many times[/b] One thing not mentioned in Brian's excellent explanation is the "measure several times, cut once" axiom of building anything that requires exact measurements. I generally measure four different bullets of the same type from the same box three times each after verifying these four bullets vary less than 0.001" base to ogive in length. Then I take the average of these 12 measurements as the CBTO. It is interesting how some bullet brands/styles are more consistent than others when selecting the four bullets to use. If you like this be sure to read the full Burger article as it has several other recommendations based on establishing the best CBTO and then moving on to powder weight. I sincerely appreciate Brian and Berger sharing this information with the long range hunting community. It has really helped me develop better loans with Berger and other brands of bullets. Thank you [/QUOTE]
