I have never owned a .270, but I've seen what they can do.
They seem to work!
I generally use a .308, sometimes an "06, or .45-70, or .30-30, or........
The deer my buddies have shot with a .270 died in exactly the same manner as the ones I've shot with various rifles.
I did notice a slight rainbow coloration around the wound, though.........(grin)
