[QUOTE="4ked Horn, post: 68016, member: 11"] [ QUOTE ] I'll say that it most likely would not effect bearing surface length, and here's why. To measure BS length a basic tool is used in order to engauge the bullet at a specific diameter on both ends. [/ QUOTE ] This is exactly why I thought the larger or smaller dia would change the BS measurement. If you increased the diameter by .001" the ID of the tools would rest farther apart. If the ogive is tangent to the BS that one thou dia change would be maybe a 10 thou (or more) length increase on the BS. [ QUOTE ] One thing to remember though is that most bullets are not uniform in diameter along the bearing length and you'd have to decide where to measure them for comparison, then if they varied (or did not vary) in the other area you did not measure, the question what to do arises. [/ QUOTE ] Good point. I don't shoot enough to wait until I have enough with similar measurements in [i]too[/i] many variable areas. [/QUOTE]
