The only people who can issue any kind of authoritative statement is the Home Office. No good asking Doe , the GTA or AMTA as all you will get is their self interested view.
They are the people who started all this off. For 18 years all were happy with the HOC 68, including the GTA, who's members sold semi-auto's and AMTA who's members made semi-auto's.
Far be it from me to suggest that this is nothing really to do with semi-auto's but much more to do with airgunners finding out just how much they can save from buying within the E.U. and the GTA not liking it.
