MOA for Long Range Shooting

If you are going to attempt any long range shooting, you will need a basic understanding of what a Minute of Angle is.

A circle is divided into 360 degrees.

Each degree is divided into 60 minutes.

Each minute is divided into 60 seconds, but we don’t use that for ballistics, seconds of angle are just used in machine shops and in rocket science.


Minute of Angle

1 MOA = 1/60th of a degree

1 MOA = 1.047 inches at 100 yards





Most accurate long range scopes are set in quarter clicks (4 clicks = 1 MOA) or eighth clicks (8 clicks = 1 MOA) but less accurate short range scopes are sometimes set in half MOA clicks (2 clicks = 1 MOA)─ which to me is the opposite as it should be. If I were designing a long range scope, I would probably use clicks that were equal to 1 MOA.

For a .308 the difference between shooting at 100 yards and at 500 yards is about 11 MOA. That adjustment with a scope using eighth clicks is 88 clicks. If long range scopes used 1 click per MOA then that adjustment would be 11 clicks.

Most accuracy testing is done at 100 yards, because it makes the math easier, and it is close enough to see the bullet holes through a spotting scope.

Folks usually say that 1 MOA is equal to 1 inch at 100 yards, which is almost exactly correct, as 1 MOA is only slightly more than 1 inch at 100 yards.

If he's hitting the target at one mile , it's a .50 Cal. BMG round .

Nothing else has the flatness of trajectory , and the windbucking ability , of that big .510 inch , 700 grain super sleek high Ballistic Coefficient bullet of the .50 BMG .

Carlos Hathcock pioneered the use of the .50BMG as a sniper weapon in Vietnam .

He mounted a Unertal 10 Power scope on an M2 Browning Machine Gun .

After spending a day zeroing in the optics , he took it out to a creek bed where he knew the NVA were positioned on the other side and would come down to get water in the early mornings .

He layed up in position about a mile away and waited for a target to appear . He didn't have to wait long . An NVA Soldier appeared at the edge of the creekbed and stood there , taking a long look , all around .

Carlos squeezed off a round . He reported that at the moment of the shot , he noticed that that NVA had squatted down to fill his canteen . Immediately Carlos felt a moment of frustration .

However a moment later the target stood up and just then he took the incoming round in the chest .

First shot tried in the field by Carlos Hathcock with the big .50 .

The AK cartridge is only meant for short range close quarters combat, and is not accurate enough or powerful enough for reliable long range shooting.

A Tale of Vietcong Snipers and Choosing Your Battles

A Vietcong sniper was stationed to snipe at an American held hill in Vietnam.



After about a week, 10 soldiers had been wounded by that sniper, but he finally gave away his position.

An American Soldier introduced the VC sniper to a 106 mm Recoilless Rifle, and the afterlife.



A replacement VC sniper turned up, and it began all over again, until the replacement VC sniper was escorted to meet up with his predecessor by an American with a 106 mm Recoilless Rifle.



A new VC sniper replaced that one as well, but the new guy did not hit anybody. He would fire his daily twenty to thirty rounds without ever scoring a hit. Eventually he gave his position away.



The 106 mm Recoilless Rifle was brought out, but before it sent the new VC sniper on his way, an American Soldier asked his CO for permission to not fire. He pointed out the fact that if we kill that guy, they will just send in another sniper, only the next guy might shoot straight.

And the CO agreed, the safest thing to do was to keep the VC sniper they had, and they let him be.

How Does The Brand of Ammunition Affect Accuracy?

The ogive of different bullets will meet up with the lands of the rifling differently.

The exact velocity of the bullet will affect accuracy, due to vibration in individual rifle barrels.

The differences will affect point of impact and accuracy.

Accurate ammunition must be made from well made bullets of consistent weight, mass, shape, and balance; and consistent powder chargers of a consistent powder; and a reliable primer that can deliver a consistent ignition; all housed in consistent, well formed cartridge cases; and assembled with consistent crimp and bullet seating depth.

To achieve the best possible accuracy for an individual rifle, a marksman will usually resort to custom hand assembled ammunition.

If factory ammo is found with an acceptable accuracy at an acceptable price, then that is an acceptable option.
