Thread: Looking for a good all around rifle

Fairly new to shooting and currently only have a 357Mag lever action, .22lr bolt action and shotguns. I've had several people recommend a .243 to me as I'd be able to use it on deer all the way down to small game. I've also had tikkas recommended a lot however I wouldn't even know where to start with optics. Brand, magnification etc. I'd prefer if I didn't have to get a new rifle for a while that would allow me to hunt most game throughout the south island. Rough budget of 2.5k although if i could do it for less would be much better. Also dont mind going over if its really worth it. Any advice is much appreciated.
Cheers,
Lachie

Edit: would also consider a 300blk, 223, 7.62x39 and 308. Not too familiar with other cateidges. For my purposes.
