Buckclub,
Being a 300WSM hunter myself, I have 2 questions for you.
What range do you think you can take him at, and what type bullet are you using?
I have a Savage 16 that really likes the 168 grain Combined Technology Ballistic Tips pushed by 60.1 grains of H380 in Remington brass with CCI Large Rifle Magnum primers.
I get 3050FPS at the muzzle, and they theoretically carry the energy out to 450 yards adequately to take an Elk.
Inside 200, they rewrite the book on devastation.
Inside 150, I have yet to have anything NOT be DRT.
That being said, the other factors being how comfortable are you with a headshot at a given range, and what your comfort level with your rifle is.
The headshot would give more meat, but a double lung shot would also make the critter dead.
Whatever works best for you, at that exact moment in time, when the shot presents itself.
