A .338 Lapua Magnum falls way short at half the distance
Although others have a very high regard for it's possible abilities...
And a 10/110 [or similar] is not inexpensive
A 700 SPS is very commonly used in SWAT
Still, a 1000 yd shot, consistently placed well, is a feat not
mastered by many......and it takes a weapon with expensive
'skills' of it's own to do so, even for the masters.
