Killed my first deer with a Husquvarna .30-06, have owned a winchester model 54 30-06, Springfield custom in .308 norma, a rem760 in .30-06 , a 1916 spanish mauser in .308 win. and now own a tikka in .300 win mag.
I wish I had the .308 norma back but the tikka is 2.5 lbs lighter and almost fits as well. So I would say .300win mag.
