[QUOTE="BrentM, post: 770039, member: 61747"] I think you might be getting confused with those of use who separate bullets into lots by ogive. This is actually by bearing surface. We take two ogive bushings and sandwhich the bullet. That measurement tells us if the bearing surface is uniform bullet to bullet. So far the last few lots have been really close but I had 1 lot that had 3 different bearing surface measures with a total spread of .030. That is a bad lot and those bullets will not group well. In that case you can simply lot them and shoot that lot but not mix the lots. I also weight sort but I don't see much if any advantage in that so far. .1 or .2 grains has shown little difference on impact to 1000 yards. Ogive bearing surface though, does make a difference.
