G'Day Fella's,
Aussie_Hunter, whilst I have never tried to earn a $ from shootin Roo's, I have shot a couple of thousand in the process of helping out local Cockies.
All I have ever used, was a .222Rem with a fixed 10x scope. This rifle still shoots sub 1/2" groups with the "Skippy Loads" I used at the time.
The vast majority of my shots were around 100 meters, with a lot under that and a quite a few past that but the .222 (or .223Rem) was perfect for it!
This country, varies from flat open paddocks, to undulating open and forested hills and scrub covered country, so the 10x scope was pretty good, most of the time!
The properties I shot Skippy's on, are 1000+ acre in size, in and around Canberra! In fact, all of them were within 15 minutes drive of Parliament House!
I suppose, that's why they call it The Bush Capital!!!
Hope that helps
Doh!
