Calculating zero distance

[Paul1262]

This is somewhat of a Mr. Roger's question. What is the beginning point that you should measure from when determining your zero distance?

Do you mean like,

from the barrel or the scope ?

I know it sound like a stupid question but, I was just wondering what the difference would be if you range find from say the muzzle or the chamber area for a zero distance. Given a barrel length of say 26"-24" -22" and measuring your zero distance from either the chamber area or muzzle what, if any, errors might occur at ranges from say 500 - 1,000 yards. I hope this response makes some sense.

The error could be minimal but there will be an error. But if you have the ability to measure to the muzzle why not just take the extra 2 seconds and measure from the turret like you are supposed to?

Up until recently, I have always shot in rimfire/centerfire rifle and pistol matches out to only 100 yards. Getting interested in long distant shooting has given me more questions than I could ever imagine. My original question was placed in the appropriate "stupid" section. I appreciate your reference to measuring from the turret - thanks.

The error is minimal so I doubt it would matter but for discussion's sake, dont ballistic solvers calculations work from the pont the bullet is affected by gravity.

As with anything I gave the simple answer. There is a lot more to it like after you zeroed finding your true range zero. I was just trying to answer your question and what @lowlight was eluding at.

No they work from the point where the adjustment is made is the reticle or turret

use this

ranges actually work in "yards' more so than inches, you have a room for error, the only time it becomes more critical is doing stuff like scope testing.

Zero wise, you can be a couple of yards off and you will barely notice it, however, that said, the software can see the difference.

Thanks for the recommendation. I purchased the new Kestrel/Hornady 5700 4DOF yesterday.

Lowlight, appreciate you taking the time to answer my question and presenting the Hornady 4DOF video.
