thanks for all the reponses yes it would be great to use a rifle but this is a built up area and I can see there reasoning for shotguns we will be using dogs ( so I believe) it is hard to explain but basically where we are going is a bird sanctury that has a lot of bordering houses around a lake/swamp sort of habitat I guess you could say it is a little upmarket property
also the wildlife departmant has a few funny ideas about shooting it seems they can't hit things with a rifle so therefore nobody else can (I have been shooting rabbits in another park that was also shotguns only because the rangers couldn't hit them with a .22 rimfire it was shotguns only)
it would be good to use a handgun as backup but in Oz that would be VERY ILLEGAL handguns can only be used for target shooting (not live ones)
we will be in groups of 3 so hopefully nobody gets eaten!!!
