The large flightless moa were soon hunted to extinction. Weatherby guarantees a 1.5 MOA (44mm/100m) accuracy for this cartridge in a Weatherby rifle. The sights are adjustable in both windage and elevation in 1 MOA increments. Some of the birds pictured are long extinct, including moa and Haast's eagles. No individual group to exceed 1.5 MOA (0.5 mrad) extreme vertical spread. No individual group shall exceed 1.5 MOA (0.42 mrad) extreme vertical spread. The rifle has an accuracy of 1.5 MOA. The earliest moa remains come from the Miocene Saint Bathans Fauna. She was discovered while busking on a street by fellow musician Anika Moa.
