MOA for Dummies

[ShawnC]

I just saw this video and thought that anyone new to rifle sighting or target shooting who is too embarrassed to ask what MOA is might find it helpful. The instructor really makes it very easy to understand.

I like this guy's instructional videos. Generally speaking I've generally crammed everything he covers by the time I find the videos, but I like how concise and thorough his lessons are. I learned how to mount a scope before seeing his video on it, and I would definitely watch that first if I had to learn it again--likewise this did clear some stuff on MOA and how different scopes adjust to them, never knew some were one click per MOA. I guess it's easy to see why he was an instructor.

One quick stupid question though---at 100 yards, do medium/heavy grain bullets that are moving at say, 2000--->2800+fps actually drop at all? Or can they go that far close to dead flat? I'm asking because when he draws all his different charts, he always drew trajectories that were aiming 'uphill' the moment they leave the muzzle, i.e. big upwards arcs.

Or was that just for explaination's sakes for moroniacs like me?.......

thank you for the post

All bullets, of any weight, traveling at any speed, will "BEGIN" to drop as soon as they leave the end of the barrel due to gravity. At least here on earth

One thing he got wrong- He said a bullet travelling from 0-100 yards has less drop than a bullet travelling from 400-500 yards because it's slower and takes longer to cover that last 100 yards. While that is true, the reason the bullet is primarily dropping faster is because it literally is dropping faster.

Confusing? Put that way yes so let me explain. 1 gravity means a falling object accelerates towards the ground at a rate of 32 feet per second, per second. The longer something falls, the higher the velocity at which it falls. A bullet drops more at longer ranges, not only because it takes longer to travel that last 100 yards, but also because gravity has had more time to accelerate the bullet's drop

Thanks for sharing. Helped make a little more sense of MOA

They drop just like a ball thrown by a quarterback, just over a longer distance. Take an AR-15 for example. The sights are 2.5" above the bore line, so the round must go up to cross the line of sight. In a typical setup, it will cross at 50 yards, go up another couple inches and then cross again on the way down at about 230 yards.
