      Buying .300 Weatherby Magnum Ammunition in Australia

      Magnum Sports lists 5 .300 Weatherby Magnum loads, and 4 can be ordered today. Brands are Hornady, Barnes and Remington. The .300 Weatherby Magnum is a long-established belted magnum used in Australia for long-range hunting of large deer such as sambar and red deer. Loads here use 180 to 200 grain bullets, including copper and polymer-tipped designs.

      NSW law allows ammunition sales only to a holder of a licence or permit for a firearm of that calibre, and we sight it at the counter. All ammunition is collected in person from our Roseville Chase store and is never posted or couriered; ordering online lets you have it put aside.

      In-stock boxes start at $141 for Hornady 180gr CX OTF and $145 for Hornady 200gr ELD-X, with Barnes 180gr TTSX BT the top of the range at $207.
