[QUOTE="Mikecr, post: 1019062, member: 1521"] While indexing off the ogives, trimming uniforms nose LENGTH -not meplat diameters. While indexing off bases(which makes no sense), trimming would uniform OAL, again -not meplat diamters. The only time trimmed nose lengths correlate with uniform meplat diameters is when ogive radius(your datum reference) is matched. I can't imagine many matches of anything while working from bullet bases. Also, It makes no sense to trim all bullet noses to the shortest in a box. To trim properly, and off a nose datum, ogive radius is first qualified with a taper mic or similar Bob green Comparator(BGC). This should set up for best pointing results, given that best pointing is accomplished with ogive desired inserts. [/QUOTE]
