I think if you look at shootings sports as a whole you'll find that the majority of the shooters are older. all shooting sports are expensive. I'd venture to guess that the most popular ones are uspsa and idpa where you only need 1 gun and can compete with what most people already have at home. the majority of younger shooters I've known were into it because of there parents. Its also harder to keep those shooters for life. I'm under the camp that thinks the target needs to be 30s-40s. that age generally has more money, and if they have kids then that's more shooters that could potentially be pulled in.
