For ranges out to 600 - 1000 yards, you could also use a very heavy .308. The recoil would not be bad in a 12 - 14 pound rifle and wind drift would be less with a 168 gr bullet. The other options in 6 or 6.5 mm are good, too.
�That rifle on the wall of the labourer's cottage or working class flat is the symbol of democracy. It is our job to see that it stays there.� George Orwell
