how is the 6.5 x47 doing at a 1000yds? has anyone been shooting this at long distance i can see it being good at 600 but a 1000yds ? would it have any advantage over the 6br i all ready have a 6br and i am going to keep my 6br i have two rifles and have a 6.5 krieger barrel so i want to go with a 6.5 caliber for the 1000yds i have a 260 improved reamer but not sure if that is the answer either?
