Well, I'm pretty sure that anything you shoot in the spine is going to need a finishing shot, the spinal column not being a vital organ. I don't know how similar it is to the remington bullet. The hornady's have 2 cannelures, presumably to help hold it together, I haven't seen the remingtons. I definitely want a bullet to make it all the way through, but if it puts them down in their tracks, I don't know how important it is. Maybe the 350 fp is a better choice...I'd like to hear from some other hunters.
