New Zealand employed many deer culler's after WW2 a lot of these used the old military 303 but as funds increased moved to other calibers
Many went to the 222 & 22 Hi Power & a small number went to the 250-3000 only because the 250 rifle was hard to come by down here
Their daily tallies increased with these modern rounds because it all boiled down to the hunters ability
Many of these hunters shot in excess of 30 deer a day, I know one gentleman who shot 106 in just over an hour
Cheers
