Over the weekend I was discussing with a US colleague of mine about using slugs for taking deer and how some states have compulsory shotgun / smoothbore seasons (where in some cases, you can use sabot slugs through a rifled barred)
This got me thinking:
I realise in the UK that rifled or smooth sided slugs come under S1 in the UK.
Where would a shotgun with a full length rifled barrel come? Would it even be legal in pump or Semi auto?
Would be interested to hear your thoughts.
