[QUOTE="Mikecr, post: 2704733, member: 1521"] There is another ingenuity that would help here. A Bob Green Comparator (BGC). If you wanted to trim only, to same meplat diameter, you would do so w/resp to a datum high on qualified ogives. Qualified meaning same ogive shape (radius). Use a BGC to validate this, before any other measure off bullet noses. F-Class John was seeing his variance partially because his ogives were not qualified. Base-to-Ogive (BTO) is also not a credible measure to act on, because it includes too much (base length, bearing length, ogive radius). [/QUOTE]
