Applying cold therapy to a tissue injury, helps limit the inflammation by causing the blood vessels to constrict. This in turn helps to limits the blood flow to the injured site, which helps to moderate the release of the vasoactive substances and therefore helps minimizes the pain and swelling in the injured area.
Kangaroos go down easy with well placed .22LR shots, so a .17HMR or .22WMR will not be a problem. I've got both a .17HMR and a .22WMR, I prefer the .17HMR mainly because it shoots flatter, making it better for rabbits, and will easily take a fox out to 120m at least (provided you placed your shots ;)).angaroos go down easy with well placed .22LR shots, so a .17HMR or .22WMR will not be a problem.

I think you hit the nail on the head as to the origins of hunting in Australia, it more or less rose as a necessity for agriculturists. Basically, all hunters in Australia are encouraged to kill as many pigs, foxes, rabbits, goats, cats and dogs as they can, as every one dead helps our messed up ecosystems.oos would be thinner skinned and smaller than your white tail deer, but maybe .223 is too small for that. Professional roo shooters usually use .222 or .223 but they are more concerned with price, and rarely miss a head shot anyway.
