The handgun ban did not result in the end of shooting in the UK.
The Semi auto centrefire ban did not result in the end of shooting in the UK.
The lead ban will not result in the end of shooting in the UK.
The thing that will result in the end of shooting in the UK is lack of recruitment, and while shooting sports remains dominated by a lot of grumpy old farts who primarily spend their time moaning about how nothing is as good as it was in the old days (despite a marked reluctance to give up those benefits of modern life that make them more comfortable), there's not much to attract youngsters in. Only doom and gloom.
If every single FAC and SGC holder were to mentor a young person, teach them, encourage them, support them in their own FAC or SGC application when the time came, then the future would be assured. And those youngsters would be better placed than the current crop of old farts are to work with, rather than against, change in society's perception and acceptance of shooting, and the inevitable changes in legislation that accompany that.
Lack of role models and people willing to be mentors is what's killing shooting sports, not legislation.
