[ARCHIVED THREAD] - New FAQ entry: What distance should I zero my rifle at?

Posted: 1/29/2011 7:23:22 AM EDT

Sylvan has
graciously accepted the challenge of writing a brief article about what
distance you should zero your rifle at based on his combat experience.
Look in the FAQ for the link.

Thanks a bunch, Sylvan!

Everything he wrote makes perfect practical sense.

A couple of quick questions:

Can it be assumed that the round flies basically flat out to 100m?

How much of a difference in point of aim to impact is there between 25 and 100 meters? Stated another way, how high would you have to zero at 25m in order to be on target at 100M?

You'd have to be a little more than an inch LOW at 25 yards when the round is dead on at 100 (assuming a sight height of 2" above the bore). That would go to -1.9" with a 3" sight height.

As far as the round being "flat" with a 100 yard zero: You'd be +/-2" out to 200 yards - this is assuming a sight height of 2" above the bore. YMMV slightly depending on that factor. I used a generic 55gr load with a MV of 3100fps for this example.

Thanks, just wanted a rough ball park figure. It's late and the numbers don't want to compute.
