Well sort of, but you've got a few facts wrong
It was the food marketing people (British Game Alliance ??) who decided to only accept game shot with lead free for sale, which has forced the shooting organisations to push going lead free, if the meat is for the food chain.
And the HSE are only following a Europe wide wide proposal to completely ban lead projectiles,
thankfully after Gov't consultation it appears airguns & rimfire have been exempted & centrefire granted a time extension,
but because lead free shotgun carts already exist it does look like a lead ban for them
Anyway I can't find the article, but still advise against it.
