I used to be a crack shot with my Weatherby .257 magnum, but that distance seems impossible, almost hard to believe. Not saying it didn't happen, but my God, I can't even wrap my head around the 1 mile shots you occasionally hear about.
So is it true that some snipers now use the .338 Lapua over the .50 BMG? I hear it too is capable of astonishing accuracy and ballistics at long range.
