Sounds like they have made it almost like a closed cert to me.
You can use your rifle whilst deer stalking (thinking there refering to payed place to stalk e.g. your off to scotland for a day out dsc1 or 2 stuff etc) or on ranges, Or on land deemed suitable by your police force (e.g your land you have got permission on that they have checked)
Nothing stopping you shooting/lamping fox on land you have cleared buy police force to use or AOLQ for that matter
beside each weapon system should have (experienced - Open)
As you said you had supervisions removed make me think its closed.
But well Iv never had a closed cert thankfully and got AOLQ. Prob one of the few thats had open cert from first applying.
Mine reads as like this
