I'm new rifles and have been thinking about how to go about zeroing my rifle. At first I watch youtube videos and read some threads here on combat zero. Zero at 25m that makes for a 300M zero with a peek of about 8.3 inch above line of sight. Generally I'm shooting in tactical matches with ranges from 20 to 200m .
I went here to get some basic numbers ShootersCalculator.com
and they have a calc for PBR, Point Blank Range.

Basically you put in your cartridge data and target size and give you a near and far zero with an estimated high or low zero at 100 years to keep your bullet on target while only having to point at line of site.
Does anyone use this method with their rifle? The idea is that you don't have memorize hold point for various ranges as long as you are inside the max PBR.
You can obviously still use hold points for more bulls eye type shooting, but with a PBR for a 6 inch target with 223 ammo you'd set your 100 yard zero about 2.18" high and that you allow you to use simple line of sight out to 311 yards, in theory.
Comments? It seems like your flattening out the trajectory to make for high and low on target size.
