If your a decent shot, anything will work. There are certain types of bullets I would rather use, on certain big body animals.
In .223 I would probably shoot the 60 grain Nosler Partition to get maximum penatration on say a bear size target.
Encore I didn't use a .223 when I did that, used a shotgun with 7 1/2's. It worked though. Your killin me man.........
