Well Terry Doe has stated that sub 12FPE semi-auto air rifles are prohibited.
If this turns out to be correct then we know exactly where the blame lies for this.
With the GTA.
It would also become clear just who does stand up for airgunners and it certainly won't be the GTA or AMTA or Terry Doe. His statements on this matter have placed him firmly in the camp that does not have airgunners in it.
