Yes, but you are American and maybe considering the norm among you countrymen.
Now I’m not a gambling man but the .30 ought six would not be in the possesssion of the majority here .
I think, and I hope I have some idea of what I am saying that .308 would be more prominent among hunters down under.
My feeling is that .243 and .270 are popular as are some magnums and then the metric European chambering s.
I like the 7mm-08 myself but it’s not as common.
The .30-06 is readily available but don’t run that poll based on Australian statistics you might lose.
We use a lot of .223 for spotlighting and it’s the mainstay of professional roo shooters
Now it seems like you Yanks churn out a pile of brass from your AR ..223s but they are restricted here.
In all I guess it’s where you choose to run the poll. We are a far smaller population and economy but for various reasons I think the .308 would be the most common .30 cal in Australia
