Bigcountry, what encouraging would I need? I use a .308 or 7MM RM!
A little overkill, but you can't kill 'em too dead! I also go for the best target possible, heart/lung shot!
You won't see me recommending any .22 or head shots either! As I said, the very BEST that I can say about the .22's is IF its legal, then you are legal!
You could drive a railroad spike with a claw hammer, but you could drive it better with a sledge hammer!
