Hunting and Shooting - Educating a New Generation Of Hunters & Marksmen From Trigger to Target - MOA
I am very honest about explaining what I am trying to write about / accomplish when I begin these postings. So that the reader can determine if they want to the take the time to read the entire posting.
For a while I have wanted to write a couple of new blog stories:
1.About hunting and why we need to introduce new hunters to the sport., i.e.., young people have so much to entertain them these days and are leaving the sport.
2.About Shooting long distances e.g., over 300 yards, what knowledge is required. I like hunting rifles, as someone once said " The only interesting rifles are accurate rifles.
What has been holding me back?
The purpose / intent of My blog is to write about ‘All Things Bayou Pigeon’. I feel obligated to link any story on this blog to the purpose / intent of the Blog, i.e., Bayou Pigeon Folk life, History and / or Heritage.
After some thought, I asked myself, what kind of stories would interest the people who are already familiar with this blog. Obviously, anything about Bayou Pigeon Folk life, History and Guns.
I know most of the men that I see on the Pigeon Facebook friends list are passionate hunters. Most hunters like guns and have more than one. Cajuns like to shoot anything before they eat it.
I like stories that weave in educational aspects as well as entertaining to read. If I can connect Bayou Pigeon Folk life, Hunting and Guns, I would have a good story line.
It was called Creative Writing 101, in college. It is Easier Said Than Done, to write an articulate story.
Background Info-
In the 1990’s most landowners stopped the hunting deer with dogs on their lands, with nowhere for the dogs to run, dog hunting disappeared from hunting clubs. Still hunting only became the dominant form of hunting deer.
Don’t get me wrong, hip boots and boats are still modus operandi. But, we have added surface drive low water motors and boats, all-terrain Vehicles (ATV’s). Shot guns have been replaced with modern center fire deer rifles.
Moving away from hunting deer with dogs changed hunting styles. Why, How ?
Without dogs and drivers to move deer, hunters started hunting from elevated blinds / stands, i.e.., homemade tree stands, and / or ladder stands with rifles and bows, trying to ambush the deer in twilight hours when they are moving to feed.
In the Atchafalaya Basin, during the day deer are deep in the swamp for protection and there they just sit out the day. In early morning and evening, they’ll come out to feed on high ridges and edges of swamp terrain.
Sometimes this requires long shots, such as watching down a pipeline or power-line right of way.
Gone are days of sighting in your trusty 30-30 lever action by hitting a 5-gallon bucket at 50 yards.
Understanding modern shooting ballistics / theory is required for deer hunting and especially for long range hunting & shooting.
Minute of Angle - From Trigger to Target
Did you realize that hunting can teach your kid one of the 3 R’s…’rithmetic. Hunting is a science ie., an ethical hunter has to be marksman. A person's level of shooting proficiency is referred to as his/her marksmanship.
Hunting, Shooting and Rifle Scopes
The rifle scope is basically an optical device that has telescoping lenses, which makes it easier to hit targets from a long distance. Today, they play a huge role in hunting and shooting. Rifle scopes are meant for extreme situations, where you cannot make a great hit with your bare eyes. Not to mention those of us with aging eyes.
Rifle scopes play a huge role in ensuring that the shooting experience is made easy and enjoyable as well. The rifle scope is endorsed for a more safe and perfect shooting in the field.
Hunters must know and understand how to adjust the elevation (up / down) and windage (left / Right) to 'sight in" the rifle.
This where “MOA” = Minute of Angle comes in play.
MOA is the unit of angular measure for adjustment of the scope to get on the target.
To understand MOA, you must first know some ’rithmetic, let’s review some basic mathematics ...
A circle is a shape with all points the same distance from the center. It is named by the center. The circle to the left is called circle A since the center is at point A. If you measure the distance around a circle and divide it by the distance across the circle through the center, you will always come close to a particular value, depending upon the accuracy of your measurement. This value is approximately 3.14159265358979323846...
We use the Greek letter (pronounced Pi) to represent this value. The number goes on forever. However, using computers, has been calculated to over 1 trillion digits past the decimal point
The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. Circumference: The circumference of a circle is the distance around it. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.
or Pi is the ratio of the circumference of a circle to the diameter. Thus, for any circle, if you divide the circumference by the diameter, you get a value close to . This relationship is expressed in the following formula: 
The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter. Thus, the diameter of a circle is twice as long as the radius. If the radius of the circle is known, all the other parameters can be calculated.
Important information can be determined for real life applications based on the parameters.
Such as, important stuff, artificial satellites that are launched travel in orbits of certain circumference. Other stuff as well, e.g., tires, Ferris wheels, rings, steering wheels, pizzas, cakes, pies, buttons, etc. Circles are simply closed curves equidistant from a fixed center.
Angular Measurement of a Circle
It is used for measuring in the study in the sciences of astronomy, navigation, and in shooting sports, where man made optics (scopes) are used and thousands of other real life applications.
Just as we have various unit systems for measuring lengths (inches, feet, meters, light years, etc.), we have various unit systems for measuring angles. One system in common use, is the degree system. It is the oldest system (dating back to the time of the Babylonians).
Most Engineers, Mathematicians, measure a circle in degrees. A circle is divided into 360 degrees.
An angle is the space between two straight lines from a singular point, i.e., the center of a circle.
In the USA system, a full circle is divided into 360 degrees.
Why 360 degrees? Probably because old calendars in ancient times used 360 days for a year, i.e.., when they watched the stars, they saw them revolve around the North Star one degree per day.
Also, did you know, 360 can be divided exactly by 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120 and 180, which makes a lot of basic geometry easier.
The Shooting Sports and MOA = Minute of angle.
MOA – is an Angular measurement, which Works cohesively with the U.S. measuring system.
Explain:
As a circle is divided into 360 degrees, and each degree is divided into 60 minutes. Therefore, if we multiply 360 degrees x 60 minutes, we have 21,600 minutes in a circle. A minute is just a fancy word for 1/60th. Think about sixty minutes in an hour and minute is 1/60th of an hour. Similarly Minute of angle is 1/60th of an angle, this angle is on a circle having 360 degrees and this angle is one of those 360 degrees. So, Minute of angle is 1/60th of one degree.
As the minutes radiate from the center of the circle, the distance between minutes on the circumference increases. Thus, the distance from the center determines the MOA.
Now consider MOA at 100 yds. From the center of the circle to the circumference is 100 yds, or the circles radius which equates to 200-yard diameter. The circumference is equal to 200 yards times 3.1416 (pi) or 628.53 yards. How many feet does this equate to? Multiply 628.53 3 feet per yard and that equals 1884.96 feet. Convert feet to inches:1,884.96 feet times 12 inches per foot equals the circumference 22619.52 inches. The distance between the minutes at 100 yards equals 22619.52 inches divided by 21,600 minutes, for 1.0472 inches in decimals or approximately 1 3/64” in fractions or 1 MOA (minute of angle).
Minute of Angle and Modern Rifle Scopes (Optics)
Rifle scopes have turrets and (cross-hairs) reticle's
Turrets are a critical component to the rifle scope. If you’ve never seen a scope, they are the little knobs on the top and most commonly the left-hand side of the scope. Occasionally you have three turrets, but two turrets are universal. The overall job of a turret is to make the adjustments necessary to zero an optic.
Most hunting scopes have covers you can remove to show a little dial with graduations.
All rifle scope cross hairs adjust elevation (up and down) and windage (left to right).
To get your bullet to hit where you want it to go, you make adjustments to your rifle scope, (i.e.., to get closer to the bull’s-eye) in MOA, up/down or left / right, whatever is needed.
Hunting scopes often have tactile click adjustments that are typically ¼ MOA, some scopes have a ½, MOA adjustment.
Scope Manufacturers use MOA (angular measuring system) to set the scope to get closest to the desired point of aim (bull’s-eye).
Remember, 1 MOA is always 1 MOA regardless of distance. When you add known distances to the mix, you can translate MOA to linear size downrange
If you know the size 1 MOA equals at any known distance, (you must know the distance) you’ll know how much adjustment you need to achieved desired point of impact.
Real life example
Hunters fires 3 shots at target at 100 yards.
Example above , known distance = 100 yards, with a 1/4 MOA scope, you’ll have to make 12 clicks right and 8 clicks down to get this group of shots to move to dead on bulls-eye.
For distances beyond 100 yards, you must also know Rifles Ballistics i.e.., your bullet drop for the distance, for your rifle, ammo, and conditions, i.e. Caliber, Bullet weight, Velocity (FPS).
Point Blank Range
Knowing your Rifles Ballistics, most hunters sight their hunting rifles to be approximately 1.5“ to 2” high at 100 yards. This makes, most center-fire hunting rifles hit dead on at 200 yards.
This is considered optimum, because for most medium range high powered rifles bullet drop at 250 yards will be less than 5 inches. This allows for what is called point-blank aim point, i.e.., no hold over needed. This will a put bullet in the kill zone of deer size animals.

Point Blank hold for up 250 yards to Target
Scopes with Bullet Drop Compensators (BDCs
Many modern scopes come with Bullet Drop Compensators where additional marks on the cross-hairs are in 1 MOA.
Therefore, if you know ballistics for your rifle, ammo, and conditions, i.e. Caliber, Bullet weight, Velocity (FPS) and projected bullet drop. Bullet drop can compensated for.
Ballistics for 270 Cal. with 130 gr. bullet
Always think in increments of 1 MOA for whatever distance you are shooting. For example, imagine you are shooting at 300 yards. You know that a MOA spreads out 1″ per 100 yards, so 1 MOA at 300 yards is 3″. You have sighted in your rifle to be +1.4 inches at 100 yards, per the chart above. Therefore, for your calculations at that 300-yard target, you should think in 3″ increments. By doing so, you can easily see that requires you to elevate 2 MOA to compensate for -6.3 inches of drop in the chart above.
If you are shooting a target 400 yards away, you can see 1 MOA at 400 yards is 4.188 inches. Therefore, to compensate for 18.3’ of drop requires you to elevate to 4 MOA tick mark.
Shooting & Hunting are a science lesson in and of itself, therefore school learning of 3 r’s is required to be a good hunter.
Hunting is necessary… we need to spawn new hunters for the future!
Hunting is not only about killing of one of nature’s creatures. It is well documented that hunting teaches many positive life skills, such as ethics, and integrity patience, proper preparation, endurance, realistic expectations, the ability to cope with disappointment, the ability to overcome difficulties and how to or not to respond to the unexpected. Not to mention, gun safety, the environment and conservation.
Hunting serves conservation and the environment by controlling overpopulation of wild animals. (Humans and Nature: Hunting Serves the Environment by Controlling Overpopulation, by Jessica Wapner;2017)
Researchers found that when it comes to problematic overabundance of animals, hunters serve their ecosystem well. By helping with regulating populations, hunting helps the environment as well.
Despite what you may have heard or read annual hunting licenses sales across the USA are holding steady. Over 15mm license hunters in 2018.
However our population is increasing! License sales are not keeping up with the increased population!
"It's questionable whether there will be enough hunters in the future to really manage wildlife populations!
In conclusion
I hope this story informs, entertains the readers on why it is important to facilitate new hunters and that hunting demonstrates & can teach practical use of school learning. Therefore, it is a value adding pursuit.
This hunting season take someone new to hunting with you. Remember the excitement that came with your success in your early days hunting…
Preserve the Heritage & Aim Straight …
