Some of what I've hunted and shot.

I remember impressing myself one time hitting a dingo with my .375 with a 300 gr RNSP at 220 yards.

The big bore boar hunt here at NE, a striped bush panther (feral cat) head shot with the same.

Lots of feral pigs with the .450, .375 and 9.3x74R. A good number of warthog with the same.

A few bunnies and other hoppers.

I'm not big on using the bigger bores or even medium bores on small game. Rabbits can be practice however.

I'd prefer feral goats, pigs and roos on destruction permits for big bores.
