I agree that BASC seem to have an engagement problem they don't know how to fix.That was my experience. The orgs and the names were just there to see each other - not the membership. The atmosphere wasn't welcoming, the staff looked either bored or ****ed off, and any questions that pertained to either shooting or conservation in Britain were treated as an annoyance.
It doesn't help that most of their members are angry at them (a) for capitulating to the lead lie and (b) for their inability to find landmark cases to bring wayward licensing into the light and into line.
This aside, they don't go out of their way to attract people to their training and activities, or to challenge the antis who claim to be conservationists with the solid evidence that shooting puts more genuine cash and more working hours, and literally more boots on the ground, for conservation that actually conserves landscapes, habitats and biodiversity, than any other sector.
No wonder they mostly just stand there talking to each other.
