I have one of these Ruger No.1 in 450/400 3" NE. I bought mine 3 or 4 years ago and it one of my favorites.

In the US brass is tough to come buy, loaded ammo is around. I don't know about in AU.

I have taken Whitetail deer and feral hogs with it. I am taking it next month to Canada for a black bear.

$2950 AUD is about $1925 USD which is about average for this gun in this chambering here.

Given what you fellows hunt in AU it seems to me this might be a good gun to use.

If you do buy, make sure you ask the seller for the unfired ammo and brass.
