I am looking at building a rifle. The rifle will be used for hunting deer and elk requiring some stopping power. Additionally I would like this to be long range capable. To achieve this I have decided to go with a 300 win mag caliber for sustained range, power and accuracy. As most people suggest building your weapon around your scope, I have selected the Nightforce ATACR 5-25x56 MILR scope. However, I seem to be running circles when looking at options for rifles. Can anyone suggest a good 300 win mag caliber rifle that has treated them well or has performed well in their opinion for my needs?
