Eric, the danger from legislation is the banning of big bore firearms. It has been threatened before, and in SA at least the cops claimed anything bigger than a .30-06 was not needed as a .30-06 could kill camels, They said interstate or overseas was irrelevant. So in reality only the NT could have the big bores, and some dickhead would be sure to say water buffalo can be killed with a .308 .....

However this wouldn't affect the USA market other than a new supply stream opening for a few years perhaps dampening prices in the short term.
