In the actual book, they record the velvets separately, but they're in the same category. For what it's worth, a monster that qualifies for B&C must have the velvet stripped off I believe. Boone and Crockett does not accept velvet entries, but Pope and Young does.
Probably because there aren't many places you can hunt velvet bucks with a rifle but there are a lot where you can hunt them with a bow.
