I’m curious as to how custom bullet makers monitor quality control over their finished product. I don’t understand the process but am trying to get familiar with the process. #1, are the jackets used weighed and measured for thickness and length, if so are they sorted prior to use. What variations are acceptable as to length and thickness. Can the jackets be trimmed and can they be chambered prior to use. #2 are the cores weighed and sorted prior to use. One would believe that if all components are identical, the finished product would be identical.
