True on the latter point. BASC were saying 'No evidence, No change' but then changed this. I tackled someone from BASC on this point and was told it is because birds that ingest lead shot die unseen and are later consumed by scavengers. I then asked for the evidence for that but they could show none.

I have a Harrington & Richardson single 10 bore that is heavily choked and the barrels at the muzzle are very thick. Perhaps tome to conduct some experimentation! Most it could do is open the choke up a bit. Lagopus.….
