ruraldoc,
Excellent post, with some good information.
On the other hand, I'd like to quote an old elk hunter I know here in Montana, who killed a pile of elk with a .270. I told him once that some people claim the .270 doesn't leave much of a blood trail.
He snorted and said, "Son, with a .270 you don't NEED a blood trail."
Since I'm pretty sure the statute has run,let's just say that I know 'a guy' who used one 150 grain partition from a 270 to make two blood trails in the snow that led a short distance to two very dead bull elk,not an intentional event but things do happen.
Hunting is like a box of chocolates.......
