I'm an advocate for bigger is better if you can shoot it well. I used a 225 grain bullet and if I had to do it again, I might consider a 250 grain bullet for my .358. This doesn't happen if the bullet used is larger. It can't hurt...
To me a good neck shot is an instant no brainer for a deer, though I never use them. For a moose, I"D seriously think twice about EVER doing it.
