Man, I can think of a bunch of really awesome ones. One was my ex-wifes uncle who owned a gun shop. He favored a 7MM Rem Mag. Because sighted in 3 inches high at 100 he could hold on out to 500 yards and had made 800 yards shots on antelope with just a sliver of daylight under the crosshair . you needed no lead on running animals.
Just last week a guy at a gun shop told me he has a 338 Lapua that shoots 1" groups @ 1000 yards . That's quite impressive!!!
