Thread: Selection of caliber for new shooter(s)

Myself (M, 52) and my little guy (M, 11) are looking to get into rifle shooting, eventually hunting.
I haven't fired a rifle since I was in my mid-teens; I've taken my little fella to the NZHA range twice in a couple of weeks and he's doing ok on the club .22
I'm getting myself all set up for the NZ FAL and should have a gun safe sorted this week and can submit an application.
Question of rifle caliber to get, as I am getting conflicting advice.
Caveat, I can probably only get one rifle to last the first couple of years.
Thoughts:
A .22 (rimfire) has been recommended as the ammo is cheap, no other reason. It is ok for small game like rabbit.
The 17HRM has been recommended for greater range, accuracy, flat trajectory and stopping power on small game ("it will easily knock over a rabbit"). Range slightly further than the .22.
I've considered a .223 as the eventual aim would be hunting larger game (up to goat, I believe, with the 223) and get into the hills. 'Proper' hunting. Almost. Can get onto the 200m ranges.
I haven't considered 'larger' (more powerful) than a 223 as simply not ready.

Now, I know if I ask 10 hunters I'll get 15 opinions, but with that said, would welcome your thoughts and opinions.
