Name the ranges where you have shot that have 36 yard target backers. Anyway, all that is good for is to get on paper, followed by correcting the come ups for the range to be shot. Or, an emergency zero when there is not time to do anything else. If you refuse to adjust the sights for different ranges, then understand the maximum point blank range for your rifle and cartridge. Set a personal vertical limit, and then figure out when to hold high and when to hold low, or in the center. https://www.chuckhawks.com/mpbr_hunting.htm The idea of Maximum Point Blank Range is the reason these short range zeroes work for some applications such as hunting or busting dirt clods and hitting steel targets at ranges past rock throwing distances. https://www.backcountrychronicles.com/wp-content/uploads/10-inch-kill-zone.gif Quote HistoryQuoted:

I like the 50 less than 3" off out to almost 300 yards which is generally within the margin of error for most field positions. The 36 is too much hold under at 100 but would be better with irons and lolipopping.

I do 50 for everything. If you like 36 go for it. As long as you know your holds/drops it doesn't matter. If you have a BDC like the ACOG follow their procedure. I like the idea of never more than 2.5" off center from 0 - 250 yards and a little hold high (chin/face) for 300. That's not hard to remember. I use 50/200 for my ARs, except my precision rifles, which are 100 yards. |

Quote HistoryIt's that 5.8" @ 175 yards vs the 2.4" @ 150 yards that kills me.
The 36 yard zero is dead on between 300-325, but a 5" holdover at 300 with the 50 yard zero isn't bad, either. It's still within the same accuracy radius of the 36 yard zero at that point. Thanks for posting the charts, btw! It's nice to see them side by side for comparison. |

Right. Realistically you are more likely to have a target within 200 yards and behind cover, etc., so you should expect a head size target The current discussion applies more to single-zero red dots or optics with no holdovers in the reticle. The 50 yard zero trades a tighter muzzle to 250 vital zone for needing to know hold-overs at 3-500 range. |

I zero at 100 no matter what the cartridge. Since I never take shots over 175 yds or so that works out just fine for me. As an aside, I cannot stand scopes that have a reticle so cluttered it looks like a wiring diagram for a laptop.

If you have 3 moa accuracy and are shooting at 170 yards with you aim point 5” high your shot could be 8” high. That’s a miss on a head or prone target.
I’m much less concerned about >200 which is low probability |

I choose 50/200 because it is within my normal shooting ranges. I prefer the slightly tighter group within that range and have to holdover a bit at 300. If my regular shooting took me to 300 yards and my goal was simply an effective hit from 0-300 then I would switch to a 36. It really just depends on what you want/need your rifle to do.

While in the Army, I attended a 2 day ACOG training course that was taught by one of the two guys employed by Trijicon who's soul job is training the military on the use of Trijicon products. He also helped write the Marine Corps marksmanship doctrine before he retired and went to work for Trijicon. He recommended and taught the 33m (36 yd) zero. In fact, that's the only way to ensure the stadia lines meet up at the appropriate distances on an ACOG.
