Case sizes

We use a standard set of codes to indicate case sizes for extractors and decappers.  Generally listed under the most common caliber in the group for us, extractors and shell holders which fit one case in the group will work for all calibers in the group.  So if you have an extractor in size #9, it will suit all calibers based on .45 Basic brass including .38-56, .40-65, .45-70, .45-90, etc.
