It's the Indian to a far greater extent than the arrow. Shooters are often at fault when things go awry, in my experience, but the bullet gets blamed.
I've never seen anything shot well with a 243 not die. I've never seen a Partition fail to kill an animal shot in the front half, though some animals seem to want to live more than others.
As far as deer-only hunting goes, I generally label the 243 a "big gun," with a 223 being more of a standard. I often see deer shot with 30 cals that run farther, sans spine hit.
In my experience, there is nothing wrong with Nosler seconds in terms of accuracy or terminal performance.
