Australia de-armed pretty successfully.

Australia has more guns now, and more guns per capita, than it did at the time it almost unified all gun laws.

It didn't "de-arm" - it brought all states and territories into near alignment on gun regulation.

If you're interested I can link to good footage of my actual IRL neighbour shooting 24x24 inch targets at 5,000 yards, here in Australia.

Alternatively you might be interested in Australian footage of feral control, taking down 800 oversized wild pigs in 4 hours from a helicopter.

		It significantly de-armed. Most importantly, Australia removed "self-defence" as a reason to own firearms. You have to be a farmer, hunter, or belong to a shooting club. While the number of guns increased, the number of gun owners dropped. And the new regulations enacted this year drop the number of guns one can own even more. There was a near-total ban on "military style" guns. See how the terrorists at the massacre last year were limited by the type of guns they had access to, only managing to kill 15 despite having all the time in the world. An Ar-15 or similar weapon could have been used to slaughter that 15 in under 15 seconds.
