As of July 2015, the Boone and Crockett Club provides official score charts on its website. On the home page, highlight the Big Game Records tab. Scroll to Scoring Your Trophy, and click on Score Charts PDFs.
The next page has links to official score charts for many animals, including bears, cougar and jaguar, walrus, rocky mountain goat and musk ox. Charts haves spaces for measurements, points or both. Information must be collected by B & C official measurers.
To find a local representative, click on Find an Official Measurer under the Big Game Records tab. Some charts also require trophy owners or hunters to identify the geographic locations where animals were killed.
