Thats how they taught us to zero the m16 in the Army, its nothing new. I use a 100 yard zero myself though.

That article is wrong. The military still uses the 300 yards zero.
Thats how we zeroed in the Army anyway. Well actually it was a simulated 50/200 zero done at 25 meters by bumping up the rear sight a bit at the zero range then bringing it back down at the 300 meter qual. range. Worked pretty well for the popups actually. Hold low on the 50 meter pop up and high on the 300 meter one. Center of mass for everything else, though holding a little high on the 250 meter pop up could give you a little more margin of error to work with.

In 2011, we zeroed at 25 meters/ 300 for qualifications. What you did isn't official Army doctrine but it's better. A 50/200 yard zero is better anyway.

I like this. You can tailor it to your desired hit radius and load.

Here is a chart that compares the 25/375, 50/225, 75/150, and 100 yard zero.
The 25/375 yard zero is terrible at ranges below 300 since it keeps the bullet too high. (Up to 10 inches high in some cases.)
The 75/150 and the 100 yard zero are similar and are good zeros but drops drastically after 225 yards.
The 50/ 225 yard zero is the best because it keeps the bullet within 2.5 inches all the way out to 250 yards. It drops after that but it's still better than the 75/150 or 100 yard zero. Those zeros are 10 inches low at 300 yards compared to 6 inches low with the 50/225 yard zero.

Travis Haley has a nice video about a 36 yard zero on Youtube.
Whatever you use, know what happens at different distances.

I should just switch to the 50/200 zero and run 62 grainers in my red dot gun. I already know the holds for it.

Yeah, when I read this originally, it simply yelled "red dot" to me.

Yep. Red dot and irons suits a 50/225 yard zero. Anything longer than 300 yards with that zero, you aim for the head to get a chest shot.
For a scope, a 100 yard zero is the best. The tic marks will get you further.
I suck at range estimations.

let's just say for the sake of argument, Im as dumb-as-a-box -or-rocks. Please explain how a scoped rifle at 50 yards is dead nuts at 260 yards. Are they saying I can simply aim dead center at 260 and I should be in the 10 ring?
Basically what is going on is that the flight path of the bullet intersects the line of sight at 50 and 200 yards. Out to about 300 yards or so if you just aim center of mass you may hit high or low but you will hit.
I thought most scopes were intended to be zeroed at 100 yards or else the stadia would be off?

At 50 and 200 yes you will be on the X. Slightly high at 100 and low after 200. This is a defensive mind set for zero. It allows the shooter to be relatively on target from 0 to over 200 yds. without scope adjustment. For precision shooting you will need to adjust your scope.
This is really more of a quick and dirty zero for iron sights, or a red dot which is essentially just a fancier version of irons.
Speaking of which, how would this zero be with 77gr OTMs? the 77 grainers are not as flat through to 300 meters.
Agreed. Also works well for the 1 X scopes. I use this zero with my vortex 1x6 with good results.

Yeah. That's why I said that.
Again, Inthought that for the reticle stadia to be accurate the scopenneeded to be zeroed at 100 meters? Or is that just for BDC reticles?
I'm soooooo confused!

Zero at 25 and always aim for the belt buckle. Don't worry about the range!
What if they are standing in a foxhole?

It depends on the scope, but most of the ones that have the BDC reticles that I've seen are setup to be zeroed at 100.

While it's hard to imagine, from the moment that a bullet leaves the barrel, it is falling to the ground. If you shot a rifle dead level to the earth and someone dropped the same projectile at the exact same time, they'd both hit the ground at the same time. The one fired from the gun would simply do so hundreds of meters down range, the other at your feet.
For simplicity sake, these numbers are approximate. There's a ton of factors that can alter them depending on ammo, barrel etc...
When you set your near zero at 50, you're actually elevating the barrel towards the target (rear sights are taller than the front), so the bullet impacts the target on an UPWARD trajectory. As it continues to travel, it reaches its highest point near the 125 mark, and then it starts coming down. It'll hit your far zero of 200 on a DOWNWARD trajectory. To hit a small target in-between those distances (the near and far zeros), you'd actually need to hold under.
It's one of those things that once you "see" it, you'll see it. I could be explaining it completely wrong, this is just how it has always made sense to me.

Yep. Reading through all this. Podmonkey cracks me up "what if he's standing in a foxhole". HahaOr get a scope that has a crude one built in like an ACOG.
