Ok so if i can ever sell my 300 wsm i have now im going to go a little fancier. Im gonna get a savage model 16 with the accutrigger and accustock. My biggest quarrel with myself now is the caliber. I have all the dies and brass for 300 wsm but could sell also, my main deer rifle is a 270 so thats out of the question. I have never killed a deer past 170 yards and. Do not have a shot anywhere possible over 300. Most of my hunting is done in thickets where i will not shoot past 75. Here are the calibers i am considering:

7 mm, 7mm-08, 308, 300 wsm, 338 win.

Input please?
