It depends on what you wanna hunt mate. I've got a .223, .243, .300, and .375H&H, as well as a .22 and shotty. A .223 is the best calibre in my opinion if you arent looking for buffalo or bulls. If legal, I'd feel very comfortable shooting anything else in Australia with my .223. Good luck, let me know what you decide.
To accurately point and shoot a cannon at a target, adjust the angle and direction of the cannon based on the distance to the target, the weight of the projectile, and the force of the gunpowder. Use a sighting device or aim directly at the target to ensure accuracy. Practice and adjust as needed to improve accuracy.

Something chambered in .50 caliber would be better. But shooting at a mile's distance, success is much more reliant on the shooter's skills, luck and comfort with their tools as the equipment itself.
