[QUOTE="Mikecr, post: 1501842, member: 1521"] I don't like to be discouraging but meaningful bullet measure and attribute consideration is really tough. For instance, when you suggest swings in bearing, is this really bearing at all? That is, are the datums on both ends of your measure qualified and isolating to just bearing, and not including ogive radius and base angle variances? Then, even with isolation to actual bearing, do you then expand measurement to other attributes, combining the differences for overall affect? That affect being to BC. As far as bearing variance itself, have you considered that affect alone? What is it? IMO, and given no testing that has proven otherwise, I say there is zero affect of bearing alone. It contributes nearly nothing to BC, and it does not affect pressure as is widely assumed. But test it and see for yourself (I have). [/QUOTE]
