Based on a recently released article where a NEW WORLD RECORD was set for a 1000 yard group at 1.4 inches--supposedly the caliber was a 338 lapua necked to .30 caliber--I would think this would be a contender..

In my neck of the woods where long shots can and will present themselves most everyone sights their firearm to shoot 2 to 3 inches high at a 100 yards--which allows one to hold on the target --especially an elk out to 400 yards and still hit the vitals---I have a 300 Ultra loaded to 3400 fps=--3 inches high puts me at 6.12 low at 400 yards and 18.4 at 500--

Do hear a lot of the 6.5/284 for 1000 yard matches as well--as it has a very high ballistic coefficient with 140 grain bullets...
