Why zero your system at a range of 25yds?

I'm sure some people have asked this question before and I am sure it is easy enough to look it up on Google. But, if you aren't careful you'll be looking at a thousand pages of information and not make sense of what is up or down.

So, why the 25yd zero? Well, as with most of this stuff, it goes back to the U.S. military. But you have to understand that there is specific criteria to meet an "exact" 25/300yd zero.

It goes like this, if you zero at a 25yd target then by the time the projectile travels to 300yds it will have the same point of impact as your point of aim. However, there are so many variables that there is no way anyone can say that it is exact.

The 25yd zero also allows for a larger displacement of your POI when intially grouping and getting to that zero. Because you are only 25yds away from the target, it minimizes the chance of you being "off paper" and wasting rounds.

Whether you are a disciple of the 25yd zero or prefer a 50yd zero, understand that it also always depends on what you are utilizing that specific system for. I certainly would not want a 100yd zero for my long distance shooting, but I don't want a 300yd zero for hunting deer in the Ozarks, since it will almost always be 150yds or closer.

So, to summerize... a 25yd zero gets you a 100yd zero +/- 3" and "levels out" at 300yds +/- 6". It is dependent upon your system, your optics or sights, your barrel length, your projectile etc etc.

Either way, We enjoy having our students on the range and working with them to understand that it really doesn't have to be a complicated subject as long as we know the stats on the system and projectile.
