I just piled up an epic Mile shot a weekend or so ago.
I was on in 4, Impact. DA for the shot was 6k feet. Wind was 4~6 from the right - that's MAGIC. Cancels out the drift of a right-hand barrel twist. Any distance.
16.9 mils for 1390 AGL, 6k DA - 0.5 mils high. Hold UNDER 0.5 mils, bare miss, bare miss (don't chase it at a Mile...) - 4th round Impact.
Had a buddy go 0/10 on his gun, lent him MY gun - AND, my "HOT AMMO..." already wind doped, already dialed - he got on in 3, and declared himself the WINNER.
I was on in 4, new environment. He was on in (0/10 +3) with a dialed and wind=doped shot, given away for free-fiddy-free.
I won that one. By far.
