Not true, you need to know your rifles point blank capabilities. For example on my 300BLK for a 2" target my zero is 124y, and PBR is from 29 to 143y. Beyond that I start using the drops on my BDC.
Most of my rifles have BDC reticules, and I use PBR to setup my zeros based on the type of targets I will be shooting at (e.g. bunny size vs deer size). I use Strelok Pro to calculate my drops and it has a really good database of BDC reticules. You can either print out your drops or write them on your arm before a hunt with sharpie.
PBR gives you the best possible configuration before needing to use hold overs.
