In the course of perfecting your shooting accuracy, you will hear the word MOA. If you don’t know what it is, then shooting on target will be the hardest thing to achieve. For those who know it, they realize that some calculations are crucial if you want to improve on accuracy.
Now, what are those calculations? Will they make shooting a rocket science subject? If you are asking such questions, the information below is for you. You will see how easy it is to understand Minute of Angle when we break it down into digestible chunks that will aid you in hitting the bull’s eye every time you aim.
MOA Meaning
What is MOA? It stands for Minute of Angle as explained in the title. Here, a minute refers to 1/60th of a degree. Think about the minutes in an hour. One minute is a 1/60th of an hour. When it comes to shooting, it refers to a tiny fraction of one angle.
Why Do We Need To Measure Shooting In Minutes?
I guessed right. That's your next question. If you look at how a bullet moves, it does so in an arc which is not a perfect one. As it travels further, the force of gravity becomes larger hence the decrease in velocity. That makes the arc’s slope steeper. You may notice that you are shooting dead on at closer targets like about 200 yards away. However, as you aim further than let’s say 600 yards, you note that you are hitting lower than the target point. The distance between where your bullet hits and the target is known as the bullet drop. It's measured in inches. Read the rest of how to understand minute of angle.
the force of gravity is the same at the muzzle as at the impact point.
it is muzzle velocity, ballistic coefficient and time of flight the determines the drop.
also, do pull the trigger smoothly or jerk it!
“If you look at how a bullet moves, it does so in an arc which is not a perfect one. As it travels further, the force of gravity becomes larger hence the decrease in velocity. “
Laughable ignorance.
Gravity does not slow the bullet, and does not increase with distance.
Does nobody study Newton anymore?
Kin we wait til this author makes it a movie?? LOL
I recently (about a year and a half ago) picked up from a widow a Krag Jorgensen Springfield full stocked carbine (Philippine constabulary 1902 cartouche). It shoots ‘ok’ but it looks immaculate. At the same time I got for my son a National Match Garand. The Garand is so darn accurate for a Garand as to be unbelievable. Because I spent all I was going to spend on guns that day I had to pass up a 1920’s O3, Pre A1 in immaculate condition. A gunsmith friend bought the rest of the collection of 18 or so long Guns for 1 fixed price. A tear came to my eye over missing the 03 because buying in bulk the average price was way less than I could have possibly, in good faith, offered her. She actually was happy as most of the other rifles were worth little. I got 2 of the 3 best.
“whether a bullet is dropped by hand or fired horizontally it will hit the ground at the same time.”
Correct.
Velocity being the determining factor in how far it traveled in that period of time.
This is a prefect example of ‘competency bias’.
People listening to the news talking heads, or reading an article, tend to think the author knows what he is talking about.
But when you read something in an area that you know about, you realize how little they know.
And this applies to everything you see reported!
This article is just plain stupid in the way it describes gravity.
As the bullet gets closer to the surface of the earth, then the pull it exerts on the earth would also increase.
This is also a function of the speed of the bullet, as velocity increases, so does mass, and therefore gravitational force.
A bullet traveling very close to the speed of light could conceivably pull the earth out of its orbit.
Now I want a deer rifle that fires photon bullets.
Kills and cooks your deer with one shot.
What?
Technically in a scenario where one drops a bullet and coincindentally fires a rifle that is aimed horizontally, the fired bullet will impact the ground a very tiny amount of time later than the time it takes for the dropped bullet to hit the ground. This is due to the curvature of the planet.
Oh I get it. It was just funny to read that.
Correct. Only The other way round as shooting perpendicular to the force of gravity (not parallel as the earth is curved as you said) means you are shooting UP in regard to the curvature. So the dropped bullet hits an infinitesimally instant sooner.
It could also be a function of terrain and topography.
“Am Shooting Journal” tends to be made up of illiterate “hold my beer” type rednecks. The writing is terrible, and the reasoning isn’t much better than you’d find in a bar around closing time.
In other words, about average for 'Am Shooting Journal'.
There is really no need to “understand” MOA. It’s built in to your optic!
You’re back, to use Ahnuld’s phrase. Tanned and fit, with Cryptogram in hand?
Still jet lagged, but yes, I’m back. :)
