There is always a possiblity of a good shot and not DRT no matter how good the shot placement. Most of the time they drop, but sometimes they don't. Wild hogs in particular. It might not happen often, but when it does it is nice to have a nice & obvious blood trail. I switched to the 450 Bushmaster with the 250 gr FTX bullet 2 years ago. In that time of all the deer shot, one deer dropped, and then got up an took off into heavy brush. There was so much difference between a 30-06 and 450 Bushmaster when it comes to a bloodtrail it is no contest. No looking for drops, there is blood everywhere.
Here is a video showing what I am talking about:
