bench rest shot at 1.5” at 1000 is a far cry from a 20” kill at 2700 yards with “duty ammo” which might shoot one MOA. Like I said - two shots concecutivly? That bullet is decending nearly verticle at that range - no wind at all in 1.54 miles?. Something just doesn’t sound right to me.
The wind issue, I’ll agree on. I find the idea of “dead calm” over the whole path of 2700 yards to be.... beyond lucky. Especially if this was in mountainous terrain.
BTW - The pill isn’t coming down near vertical - my ballistics computations show it dropping something like 350 to 500 inches (depending on the Bc we’re using) per 100 yards at 2700 yards. If it were coming down at a even a 45 degree angle, then the drop would be equal to the run, ie, you’d drop 3600 inches over a run of 3600 inches.
