Most people are kind of biased in their opinons because they believe what they shoot is the best thing since sliced bread. I shoot a 7mm rem mag and have not had problems dialing at&t with that baby but i have a few friends with diff cals that also have the same capabilities if they know their rifle good enuff. Lots of guys here shooting 300s and 270's reaching out well into the 300 yard range but the question states what is the best long range deer rifle. Assuming money is not an option i would vote for the 7mm stw hands down. I do not own one but sweet jesus some day it will be mine.
