At first I thought this was a dumb question & wasn't even going to post it. But after thinking about it (that's my problem) I am not so sure if it is dumb or not. Let's say the ballistics chart for my rifle shows at 200 yards zero my bullet strikes the target 2.0 inches high at 100 yards & 1.0 inch high at 50 yards. If I sight my rifle in at a 50 yard range and the bullet is striking 1.0 inch high, will it strike dead on at 200? It sounds so simple the answer would be yes, but is it? Yup, thats why people often refer to it as the 50/200 zero.

Zeroed 1" high and 50 and dead on at 200 yards. I doubt it would be dead on but it should be close. You still might need to fine tune the 200 yard zero. Ballistic charts are a guide, there are too many variables to say it will be dead on. |

A trajectory that is 1" high at 50 yards is going to have a far zero of almost 300 yards, not 200 yards. 1" high at 50 yards

But he never said what he was shooting. He just said "If my ballistic charts says". So the trajectory of what he is shooting could match the numbers he posted. I think he just wanted to know if he could sight in using the close zero and have match dead on with the far zero. |

I said that a 1" high at 50 yards zero, is not a 50/200 yard zero. 1" high at 50 yards is not a 50 yard zero not matter what you're shooting and for a typical AR-15 set-up (the name of this site is AR15.com) 1" high at 50 yards will not be a 200 yard zero; it's going to be a 300 yard zero. 1" high at 50 yards

One more time...
He didn't say what he was shooting....what if he's shooting something that matches those numbers? You are basing your reply on M193...he might be shooting a civil war canon. And even if we stick to the AR...post a chart of 40 grain and 75 grain bullets. But...we still don't know the velocity so it's still just a circle jerk. He said "what if". |

As a person who runs slightly raised optics this 50/200 (more like 50/225 I think) zero assumes the standard height irons/optics are being used.
If you run slightly raised optics, the arch will be pronounced meaning that a 50yard zero might be 250 yards on the flip side. |
