8x56mm and Bonanza.
This is only a couple of months late, however if you are still interested in hunting the Northern Territory of Australia I think that I may have what you are looking for. I am associated with a person who owns two cattle stations (ranches) in the Northern Territory. He does not wish to become involved in the Hunting Safari business in the real sense. He does want to "value add" his resources, but nowhere near the prices of the regular safari deal. All he wants is enough to cover his expenses, with a bit of fat. On one of his properties he has several hundred buffalo and enough pigs to keep anyone satisfied for a few weeks. I recently shot (culled) 600 pigs in one area, and on Thursday next week and the following 5 days I am playing host to 4 hunters who have paid the owner to remove several buffalo from another area. These animals are playing havoc with his fences, so they are going.

If you are interested in discussing this further, please advise and we will make the appropriate arrangements.
