I am in the senior years never had a custom type rifle. Given the same cal .260 up thru .308 I would like a light rifle to shoot out to 400 yards on my farm. On the whole, which would shoot better?? Barrett, a Kimber Montana, Cooper, Rem Mt Rifle stainless action and synthetic stock. I would like to keep the cost under 1500-1600 for rifle glass would be extra. I would like to be able to get parts. Rifles have always been crapshoots. What brand would probably guarantee the most accurate rifle. I would only like to do this once.
