Honestly I don't think you can go wrong with any of the suggestions I read.
I bought a .300 WM 9 years ago, custom built by Hill Country Rifles. Left handed Win. Mdl 70 Action. It is a .50 MOA rifle with the right ammo. They told me what to shoot, I wanted to try something else, they were right! Worth every penny I paid, I have taken some great deer and thus far with prob. 30 + deer shot only 1 was needed a second shot.
Come to find out he was dead where he stood, I just didn't want to take any chances.
I put a Nikon BDC Reticle Scope on my rifle to help with Long distance shooting,even though my longest shot on a deer was 427 yards. Every edge you can give yourself fills the freezer.
Here's a link to where I got my rifle FYI.
