In the interest of sharing the wealth, I thought I would share the 100 yard zero target they use at Blackwater when sighting in weapons for their carbine courses.

The image will fit on 8.5x11 paper.

Download the full sized version here.

Set up the target at a distance of 25 yards.

You will notice that the target has an extended black line a few inches wide. This is your point of aim. Then simply adjust your sights until your rounds fall into the middle of the small white square at the bottom of the target.

When that is done, you should have a good sight in that will be within the sight-to-barrel distance of your weapon out to 100 yards. The very same sight picture is useful out to 300 meters by simply aiming a little higher on the target.

I used to use the Santose zero, but I gave the BW 100 yard method a try, and I like it a whole lot better. I was able to engage targets at all ranges faster and more accurately with a lot less guesswork than with other sighting methods.

Thanks for the link to the target, looks like an excellent method to set up the sights.

Awesome, thanks. I have my new bolt gun I need to zero and I only have access to 25 yards right now. This should work perfect.

One of the great advantages of the 100 yard zero is that it is much more practical for defensive applications, especially for civilians. (Police and ordinary citizens) Civilians are going to be faced with threats that are pretty close. Worrying about things like holdover at these close ranges is difficult. Even lining up a sight on a proned out adversary at 50 or 75 yards is a lot harder than most people realize. That is not the time to be trying to calculate holdover.

The 100 yard zero allows you to use the sights as almost POA POI at the ranges most of us are likely to face a real threat, and it doesn't compromise your ability to use the sight even at 300 meters.

At previous courses I used the Santose zero, but the difference in my shooting when I used the 100 yard zero was wonderful, ESPECIALLY at CQB distances.

If you use the AR for home defense like I do, the 100 yard zero is probably the most practical setup for you.

Since you are probably using a pretty accurate scoped rifle, I must encourage you to get to a 100 yard distance and confirm your zero when you get a chance. It should be dead on, but sometimes a slight adjustment is necessary at the longer distance to make sure the bullet is exactly where you want it. The zero is almost always within the margin of error of iron sights at 100 yards, but with an accurate scoped rifle small adjustment might be necessary.

When you are talking about ajusting you sights to make your rounds fall at a 100 yard zero do you suggest moving the front or rear sight, and what should i start off at on the back sight. I have a new a3 and i havent even messed with anything on it yet. I am new to the 15 and I want to get good with it but I dont know much about it. I want it to be fessibleat a hundred yards or less and be able to move my rear sight and get a 200,300,400 yarders thanks in advance for your help guys.

Also one more quick question when you are talking about the 100 yard zero are you saying to shoot at a hundred yard distance or use the 25 yard dist. Forgive me if I sound stupid but I have always used a scope since I was little and I am trying to wheen myself off the scope tittie

shoot it at 25 yds however saying that, the target on an 8.5 by 11 piece of paper will make the silhouette seem as if you're looking at a life size target that is 100 yds away. somebody correct me if i'm wrong but i believe this is the way it goes.....and the only stupid questions are the ones not asked

Thanks for the target.

Here is one that I created for blasting at all ranges. It is not a zeroing target, but I am sure that many of you can appreciate it. Do with it whatever you wish by grabbing it HERE

ETA: Feel free to host it anywhere and please post photos of things you have done with the target
You try to make something idiot proof, and along comes a better idiot!

Based on the bullet drop on the 25yd zero target, that's pretty much the same as the IBZ, except you now zero at 25 yd instead of at 50 yd. The trajectory puts it very close to the IBZ. The IBZ states to rotate to "3" (2 or 4 clicks up) to shoot at 300m, or you could just aim a tad higher. But this will come in handy at the range! Thanks john_wayne

Although when we were down there I did do the 100yd zero, I still prefer the 50yd Santose zero. I get a flatter trajectory even out of my 11.5" SBR out to 225yds. Good training there with you JW, that was a fun course I wish I could go back tomorrow.

Scotty and Kyle did convice me that fixed back-up sights are better than flip-ups. So I've reconfigured my 11.5" once again. (all my guns are really works in progress).


Here's what my 11.5" looked like at Blackwater.






And this is what it looks like now.

When I did the Santose IBZ at 50 yd, I noticed my shots were low at 25 yd, approximately where the white box is below the horizontal line in the 100yd zero target.

gotm4, I have never seen an Eotech mounted that far forward before. Is this where you prefer it? And in your experience, any advantages to your setup?
You do realize, that if you continue to bother me, I will shoot your pinky toe off.
