In the Northern Territory, centre-fire rifles are banned from the public hunting reserves during the waterfowl season, usually four months mid-August to mid-December. This happens to be most of the dry season, and the best time for hunting boars on these reserves. A Paradox gun is perfectly legal for boar year-round, and for geese and ducks during the season. Hence, it is probably the PERFECT gun for the 21st Century in my backyard!

As for "..not too effective", many seasoned hunters including Samuel Baker strongly recommended the inclusion of a Paradox gun in the ideal battery for India/Ceylon and the colonies.
