As regards steel shot - you are of course entitled to your opinion but your opinion is not a fact and others using steel shot for decades for live quarry might disagree with you.
As regards wildfowling and game shooting yes they are different shooting disciplines.
For wildfowling the following advice is given in BASC's code of practice for wildfowl quarry species:
a. Pochard – no take – targeted conservation effort required.
b. Pintail – take a maximum of two birds per day – targeted conservation effort required.
c. Woodcock – delay shooting until late November where resident woodcock are present.
d. Scaup – show restraint, site-based considerations required.
e. Goldeneye – delay shooting until October where resident goldeneye are present.
f. European white-fronted goose – take a maximum of two birds per person, per day.
g. Common snipe – delay shooting until 1 September where resident snipe are present
