We’ve talked in the past about how to zero a rifle. Now it’s time to talk a little about why everyone uses a 100 yard zero, and not a different distance. We have touched on this a little in the prior article but I’m going to explain it in greater detail with this article. I’m speaking primarily of precision rifles here. You may hear your buddies that shoot with an AR15 using a 50 yard or “battle zero” with their rifles. I’ll talk a bit about that as well since AR15s are a popular rifle and this is a rifle website. For a precision rifle, though, with an optic capable of external adjustments, the 100 yard zero is king!
