Not sure if this should be here or "Ammunition" but anyway.... Just came across this:
"Symbol Number: S22LRT
Lot Numbers: GD42L and GD52L
Winchester has determined the above lots of 22 Long Rifle rimfire ammunition may contain double powder charges. Ammunition with double powder charges may subject the shooter or bystanders to a risk of serious personal injury and/or death, or cause firearm damage, rendering the firearm inoperable".

Don't even know if this ammo is sold in the UK but it looks a bit nasty!
