223 zeroing

What barrel length?

Google “Revised Improved Battlesight Zero” and that will explain it although that refers to an M16 with a 20” barrel and a rear sight with an elevation drum.

I zero my rifles by adjusting the sights so I’m hitting about 1.5” low at 25 yards, at 100 yards POI will be pretty damn close to POA.

On shorter barrels this doesn’t work though.

You can get a ballistics program that will allow you to compute complete data for your rifle and ammunition combination. That's where I would suggest starting.

Here's some good info:

A bolt action generally has the optic closer to the bore than an AR15 pattern rifle, so actual tragectory will vary based on the optic height above bore. Depending on the intended use, each distance has its pros and cons.

Your zero should be set at a distance where your intended target is expected at.
The Battle Zero is just that, POA at POI at 50 yards and a five inch kill zone from 50 to 300 yards. It is zero again at 300.

I like a 100 yard zero as I like to shoot short and long (relative to the AR). My 5 inch kill zone is from zero to 225. I have learned to offset my scope 2 inches to 50 yards. My hold overs are 3 inches at 200, 13” at 300, 3 feet at 400, 20 clicks at 500, 30 clicks at 600, and so on.

This works for me because I know my rifle and my ammo.

I don't bullseye/bench shoot, but I do shoot close in to 400yds with my AR's and I settled on a 35yd zero.

High speed guys call this "maximum battle sight zero". We used to call it a hunter's zero.

No math or abnormal hold overs. Point and shoot from super close to 300yds is very easy with a 223/556.

Just remember elevation is science and windage is art. Yeah...there's always a rub.

Here are a few zeroes with other distances: https://imgur.com/a/u2C95bV

With a 50-yard zero, your POI should be within 2.5" (height over bore of standard iron sights) all the way out to 250 yards. Once you get past 250 yards, you'll have to start using holdovers.

If its a bolt action just zero it for the distance you are shooting most. I assume it has a scope so Just zero it for your most common distance and then use the dials on the scope to adjust.

[ScottsBad]

I believe the 50 yard zero takes into account the standard sight height over bore. So just adjust for hitting the bull at 50.

Barrel is about 24 inches in length. This is a bolt action. Thank you for the resources - thinking now I’ll zero To POA at 100yards.

FYI, you are asking in the "Semiautomatic or Gas Operated" sub-forum. Smartphone based ballistic calculator (like Strelok) is best bet. It will take into consideration your optic height (scope axis to bore axis, ballistic coefficient for the projectiles you are using as well as muzzle velocity (published or measured with your own chronograph/Labradar). If you don't have any of this info, find the most similar commercially available load and use published data for that. It'll get you in the ball park, then manually fine tune from there.

Strelok is not pretty, but it works. I've used it out to 600 yards with 308.
