my kids hunt deer with remington 55gr. psp .when they started out heart/lung was the the chosen target.I usually had to do a little trailing.on one really well hit, rather large buck I had to do a lot of trailing.then my 6 year old decided she wanted to shoot one in the neck! where she got that idea I'll never know, at the time I wasn't much for trying to hit one in the neck! anyway she watched lots of deer for a few days straight,then a big 'ol buck came in 115" 5 year old,I told her if you want a neck shot here's your chance! she popped him in the neck he dropped! now all my kids are neck shooters,at least until they move up to a larger caliber and no more trailing for me!
