The same thing happened to my son while shooting the Nationals in 2009. He was a D shooter, but with only 3 shooters in that group, not even a mention.
I understand the need to limited prizes to classes with only so many people, but a simple recognition during the final ceremony goes a long way to reward the efforts of shooters that did win their class.
The lack of that recognition also goes a long way, by making a very poor impression of the national organization.
I think recognition could be given in these cases, without giving a prize. They do it a the local level.
Just a thought for ways to improve the impression that our younger shooters have of the organization.
