    I have always done 50/200 however I have been considering going to 25 Yards on a couple of my guns that I have primarily for Home Defense, etc.
    Tell my tale to those who ask. Tell it truly; the ill deeds along with the good, and let me be judged accordingly.

    So, based upon the linked article, can I assume you're the single person who selected MPBR? If so, what diameter target size do you select when making the calculation(s)?

    Is there enough of a difference in POI at 25yards to be worth moving from a 50/200? No guarantees the engagement will stay in the home/play out the way one might envision it to.

    Split the difference. 75 yard zero, or is that just insane. A smidge low at 50, a smidge high at 100. Anyways, just food for thought. I used this on my 1-4X.

    It’s not insane....it’s about what works for YOU.

    There are compromises with all the different zero range lengths. You just need to understand the limitations of what ever zero you decide upon. There i# no wrong answer

    Personally I like MPBR zero.

    100 yard zero for all of my red dots. Whether it's my 10.5" SBR or 2 14.5"ers I know where each weapon hits a various distances.

    What's your preferred zero these days?

    Obviously, I can’t confirm that assumption.

    I will say that before this past spring I didn’t know much about this zero method. I can say that I’ve done more training this past year with my AR, and still am weather permitting, than I’ve ever done. For me, our team has been able to validate this method via many training sessions and scenarios and I am a big believer now.

    We selected a 6” diameter. I’m sure you can figure out why. Here’s an example of what I’m running with one setup.

    Carbine is a Colt 16” CCU
    Optic is the Trijicon TA-31 with ACSS reticle
    Ammo is Magtech 62 gr lead (non-steel tip)
    Chrono’d velocity with the combo is avg. 2950 FPS.

    Running the ballistics, the zero is 45 yds which results in max ord height of +3” at 150 yds, -3” at 300 yds, and zero at 260 yds.

    We also learned to apply this zero method to the subtensions on our reticles based on the BDC provided by the optics manufacturers. Again, practical application proves it works.

    Somebody else said it. Whatever zero you pick, learn your ballistics and holdovers inside and out. I am now comfortable with this method with various barrel lengths and optics (LPVO, RDS, and 4x) for my holdovers from 7-200+ yds. A little more effort for 300-500 yds. Ammo has remained constant.

    I’ve also leaned you have to adjust with conditions. Most of our shooting this year was in temps 60-90 degrees. The highs are going to be in the teens and 20s the next few months here. I will need to understand the effects on rifle, ammo and optics and adjust, rezero accordingly.

    I personally use and prefer a 50m zero with RDS.

    The 100 yard zero is optimal for carbines inside common "CQB" situations.

    A 25 yard zero will have significantly more change in POI in relation to POA at close range distances than a 100 zero will, resulting in more brain work requirement during a gunfight, which is usually not something that folks want at that time.

    With a sighting device mounted at 2.5-3" over bore, from 5-25, with slow & heavy 5.56, a 100 meter zero has a rate of change of right about 0.05" per yard of distance, which means that you can misjudge your distance to target without it making significant effect as a 2" hold above desired POI will work from 0-35 yards (will keep everything inside a 1.5" vertical deviation).
    Under the same conditions, a 25 yard zero will show 2.17" of elevation change, which will keep you inside a guaranteed CNS hit with 0.83" of vertical aiming error. The rate of change is around 0.11" per yard, which means that you will need to have 2-3 different holds you will have to employ between 5 and 25 to maintain the same level of precision as you would get by simply holding the same 2" across the range spectrum with the 100 yard zero.
