The zeroing at 25metres is a Point Blank Range (PBR) calculation for shooting people at typical ranges of engagement with a specific bullet travelling at a certain velocity. If you intend doing similar with your Grendel then it won't be 25M. We need to know;
1. The bullet you are going to use.
2. The velocity of this bullet.
3. The Vital Zone radius of your intended target.
Or, you can zero at 100 metres or yards and use a ballistic calculator to know your come-up's for all other ranges. I use this second technique and save the PBR's for SBR's using red dot sights.
