The previous advice sums it up. I don't load my .270 for yotes. However, how good are you at head shots? My cleanest kill on was was with my .270, 140gr SST. I happened to see one about 130yds off trying to cover real estate over crusted snow that kept breaking under him (i.e. target randomly going up and down). I by chance hit him behind the right ear and the bullet may have exited the left eye, but it was hard to tell. Very little pelt damage.
