300 & 375 Holland & Holland Magnum
I chose the .375 H&H Magnum on recommendation of my friend Tello, as one of the top dozen of the 20th century simply because few other cartridges do so many things so well. It is just powerful enough to handle game too nasty for smaller cartridges, yet it is not ridiculously
overpowered for nondangerous North American game such as elk and moose. I also chose it because the level of recoil it generates represents about the upper limit most hunters can tolerate. Even though the 375 H&H was introduced in 1912, the 300 H&H was introduced in 1925 along with the 270. Most American hunters ignored it due to the high cost of imported rifles chambered for it. But that changed for the better in 1937 when Winchester added the chambering to its list of options for the Model 70 rifle. When loaded with good bullets and fired in an accurate rifle, this old English cartridge is capable of remarkable accuracy. It’s good too; I would not hesitate to hunt any big-game animal presently walking the face of the earth with the .375 H&H Magnum. It is my favorite rifle for hunting Buffalo in Australia!

We were born to hunt. Aldo Leopold, the father of wildlife management, liked to "arrive too early in the marsh just for an adventure in pure listening."  He wrote that hunting  "is not merely an acquired taste; the instinct that finds delight in the sight and pursuit of game is bred into the very fiber of this race - the love of hunting is almost a physiological characteristic "....We are dealing, therefore, with something that lies very deep.
"Buffalo Hunting Australia" and Water Buffalo History
Between 1825 and 1843, about 80 buffalos were brought to Melville Island and Cobourg Peninsula for meat. When these settlements were abandoned in the mid-1900s, the buffalos soon colonised the permanent and semi-permanent swamps and freshwater springs of the Top End of the Northern Territory. Australia has a mixture of the two types of buffalo: the river type from western Asia, with curled horns, and the swamp type from eastern Asia, with swept-back horns. The number of feral buffalos in Australia has decreased dramatically from around 350 000 in the 1980s, due to extensive Buffalo Hunting in Australia by culling as part of the Brucellosis and Tuberculosis Eradication Campaign. In Kakadu National Park, the number was reduced from about 20 000 in 1988 to under 250 in 1996.

Ecology
Feral buffalos prefer to inhabit swamps and floodplains, where they have ready access to food and water. In years with low rainfall, many feral buffalos die, and the remaining ones are restricted to the northern river plains and associated swamps. After a series of wetter years, feral buffalos can spread again, with populations building to densities of up to 34 animals per kilometer square.

During most of the dry season (May–October), males (bulls) and females (cows) live separately. Females and calves, led by one of the older females, occupy the forested plains where food and shade are most plentiful. Males inhabit more open plains with little shade, or slopes with dryer vegetation. When the wet season breaks, the older males join the females and drive away younger males. There is a peak of mating in about March and pregnancy lasts about ten months.
In the wet (season November–April), the feral buffalo grazes on aquatic grasses and grass-like wetland plants. It eats a broader range of foods in the dry season, feeding on grasses, herbs and the leaves of plants like pandanus.
In the wet season feral buffalo groups camp overnight in woodland and move out to feed at dawn, with males eating up to 30 kilograms of dry matter each day. Mid-morning, they move to the water to drink and wallow, returning to graze from mid-afternoon till dusk. In drier times feral buffalo wallows to escape biting insects and stay cool.

Score Methods for Hunting Buffalo in Australia are:

SCI Safaris Club International
"Joining information": Are you a new member to SCI? If so, as a thank you, your 1st record book entry is free (a $35.00 value).

The SCI Record Book of Animals uses SCI’s unique all-inclusive record keeping system, the most used system in the world, to document our hunting heritage. The scoring system recognises typical and non-typical animals and both free range and estate taken animals.

NO deductions are enforced penalising animals for asymmetry in the SCI scoring system.
The Douglas Scoring System based on symmetrical size is a well-recognized system that has been used for many years by the New Zealand Deerstalkers Association. It was hoped that the Register would not only be a valuable contribution to the deer's history but also that it would provide an extension of the hunter's interest in the deer. This was an important step in the direction of having Australia’s deer accepted as a valued game animal. The first publication of the Top 10 trophies took place in 1976 in Vol. 1 No. 1 of Australian Deer. At the time, only 4 species of deer were available for legal hunting.

Before a trophy is measured a drying out period of at least 60 days after the trophy was taken must be met before it is measured. Measurement is carried out by a panel of three, comprising the Chief Measurer or a State Measurer, or a Certifying Measurer and two Accredited Measurers. All measurements are checked until agreed upon.

If the trophy meets the minimum standard for that species, and all other obligations, the trophy is then recorded in the Register.
