You may well have not had any issues in the past however the situation as changed in the last few years.
The non toxic rules here are ridiculous and the shooting community is campaigning for changes with these laws, however the shooting community has a poor leg to stand on in this regard due to the historic mass non compliance to the non toxic rules.
The situation is simple, if you want to shoot wild fowl here comply with the law.
The law is simple:
In England if you are shooting wild fowl use non toxic.
In Scotland if you are shooting wild fowl and you can see a body of water; use non toxic.
The fact that the water might not naturally be there or that the ducks are put down is entirely irrelevant.
The situation has changed as we need compliance as we currently face loosing lead entirely which would be a disaster but that is what all reports say is coming.

Many shoots will try and enforce compliance now as, as much as any other reason insurance policies would refuse to pay out if it was found that the law was being broken.
To avoid the disappointment of having to sit out the duck drive I suggest you just get a box of cartridges for each shoot day so you are covered. Or arrange your out fitter to speak to the estates to get them to drive out another wood instead of ducks.
I think its awesome you are giving the grant a home coming and I would love to see a write up once you return.
