And....
Perfect weather conditions - during the barrel warm up and Zero in prior to the challenge.
And...
NO change in light, wind, mirage, barometric pressure or humidity for the entire period..
And... Projectiles and powder that do not foul the barrel or change the geometry or drag within the barrel.
And...
Rounds that have been loaded equal to the task...to compensate for the increasing temperature of the barrel and loaded in correct order in the magazine...
And..
An observer to track the impact points and advise the shooter to change his sight picture, if required.
And...
A shooter that does not breath for the entire 20 seconds.
No time to exhale, hold, squeeze in this challenge.
And....
I'm sure I left out several other critical conditions that need to be controlled...
Plus...
A lot of luck....
But I agree....some day, with some gear -it will be done..
No doubt about it..
However ----- I would be SHOCKED to hear that the Corps is using optics on the range... Even at 1000 yards..
Snipers are the only kids that should be using optics..
Semper Fi
This is something I've never seen discussed. Care to explain further?
