Not that difficult a shot. I have a .308 rifle heavy contour 22” fire lapped barrel that all day long shoots 0.5 MOA and on a windless day often through the same hole at 100 meters, a 1” group at 200 meters, and a 3” group at 400 meters.
With the right equipment you can cloverleaf rounds at 200 meters. 7.62 is a fine round but not as inherently accurate or as wind shedding as more modem rounds in the same platform. I have a AR10 in 6.5mm 24” 5R 1:7 twist threaded that will cloverleaf at 200 and I could hand it to a complete novice and first round if I dialed it in for them they could pop tennis balls at 300m. So no not a one in a million shot at 150 yards any competent shooter could make the counter sniper shot. The suspect was hit right in the a t zone his front teath are gone in tbe high res imagery that’s a text book T Zone CNS shot from the front every tactical marksmen practices that shot religiously. In the movies you aim between the eyes. In reality the brain stem is the target not the frontal lobes. From the from the brain stem is directly behind where the nose meets the mouth that’s where you aim to shut a human off like a light switch. Higher motor function is not important sever the brain stem and the ability to move is instantly halted the body does later but the person is instantly and permanently immobilized exactly what a counter sniper’s mission is.
Ok, I have a few questions about the shooter’s corpse.
Looking head-on from the front:
If he was shot from the front why was his face intact and the right, upper side of his skull broken up?
If he was shot from the front why was bone pushing out of the lower L side of the neck, under the jawline?
High right entry and lower left exit tells me the shot came from the upper right.
Only one thing to the upper right from that position (looking towards the shooter). And it’s not a one-in-a-million shot. In fact it’s in perfect over watch of the shooter’s position.
