This is an interesting conversation. So far, seems Aussie's and Yank's favour pretty much the same cartridges.
In the States, the top 5 selling rifle cartridges are in ranking order:
1. 223 Remington
2. .308 Winchester
3. .30-06 Springfield.
4. 30-30 Winchester
5. .270 Winchester
II would be curious to see what the top 5 are in Europe.
Thinking a large portion of 223 Rem is for blasting at the range in AR's or hoarded for the Apocalypse. No doubt the 223 gets hunted but doubt it ranks number one out of those five if adjusted for other uses in the U.S.
