I have a 22 Hornet, Aussie made. It is a Lithgow 303. Converted by Slazenger to 22 Hornet. My father use to put 10 shots into about 3/4" at 100 Yards, open sights, with IMI ammo. It was not until I started using Small Pistol primers that my 5 shot groups went into about the same, with a scope. Big and heavy for a Hornet but comes to the shoulder well.

I also have a 6.8SPC and in Aust I would say it is an almost extinct calibre. Which is unfortunate as it is better than a 223 for most game. The only reason I have any 223's is I occasionally help out a professional shooter -culling Kangaroos- and the ammo is cheaper and far easier to get.
