Greetings from Norway. I am currently in the process of acquiring a long range rifle. The Rifle will be used for target shooting at ranges up to 1200 yards. The platform ive decided to use is a Tikka T3 Super Varmint in a GRS long range chassis and a S&B PM II 4-16x50. I am seeking advide on which caliber i should choose for the rifle. The calibers being considered are: .270 WSM .300 WSM 6.5x55mm Swedish (I am reloading my own ammunition, so availability is not an issue).
