I heard that Norway reversed its lead ban.

This is true, but the situation Norway faced in 2014 is quite different from where we are now, in 2020. Their principal reason for reversing a lead ban was insufficient lethality in their available non-lead rifle ammunition.

In addition, the use of shotguns in Norwegian woodland is very low compared with the UK. Furthermore, the quality of non-lead shotgun cartridges has increased significantly over the last six years and will only continue to do so during our transition period. We are not proposing any change to rifle ammunition.
