Try the 6.5 Creedmore (by Hornady). 1000 yards or meters no problema. Ruger M77 Mark 11 Target Rifle Mod. # 17980 is the one for long range. Ammo, match grade, around $25.00 per box (20) plus tax.
If you have bucks to burn, go custom....
PS: You will need a good long range scope as well.
PPS: Ruger has their own scope mounting sys. Be absolutely sure to ensure your scope can be mated to the rifle. Had to alter my Ruger to a pic. rail. Extra cost $150.00 by Ken Farrell Inc. (kenfarrell.com).
