just looking for some advice on the tikka t3 7 mm mag, looking for a rifle that will get out to 600 yards but also need a scope, i was looking at bushnell DOA 6500 . i have been shooting 3006 that is 70 years old and time to up grade. killed many deer moose and elk but would be better than trying to get close to 200-300 yards, with the old 3006. not looking to spend to much, just want some thing better . so i need some information on what go with the 7mm and the scope. thanks.
