Beautiful rifle mate. My old man used to have a Sako .222 magnum which was a round that was phased out years ago and replaced by the .223 round. Ballistically, they're virtually that same. We used to load our own ammo and go bunny busting using the Hornady 'super explosive' projectiles. They used to be the softest available and would absolutely destroy something the size of a rabbit. Actually good for foxes too as they wouldn't actually exit......just disintegrate inside for an instant kill. No good for heavier game though though as you need more penetration.
Used to go pig hunting years ago and my favourite weapon of choice was a Marlin .45/70 lever action. Choice of 300 or 400 grain flat nose projectiles!!! She was a beauty!
My old man had a Remington 7mm magnum. Now THAT was a rifle that packed some punch, and shot very flat over range as well.
Have fun mate, and be safe.
Cheers,
Brent.
