I don't know many folks who go out and choose a .308 for their deer rifle. As a matter of fact, I don't know anyone who deer hunts with one in my neck of the woods.
I have a .308 (only one I ever owned), but I have to admit it was the rifle more than the chambering. I have a late 60's Bofors full length stock Sako carbine. I fell in love with the rifle growing up and reading that John Wooters had one.
I have killed a bunch of deer with it and so have members of my family. It has now become more of a designated "treestand rifle" because it's so darn handy. I keep a .257 Roy for the open fields. Have a few other favorites that I cycle through, but these are my go-to guns right now.
That said, I wonder how the .308 Win ranks in sales every year?
