I've looked through a couple threads, but can't seem to figure out why people don't seem to like the 36 yard zero.
What does the 50 do better? Pic of my rifle operating in the theater of my office. 
I may or may not be in nothing but my chest rig. |

Idk 50 yard zeros for irons and 100 for magnified optics has always worked for me out to 300 or 400 yards so why change now

It doesn't matter what your zero is with an EoFag. As soon as you deploy to Minnesota you're fucked.

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. |

You can zero at whatever distance you want as long as you know where your other zero is and if it is consistent with the kind of targets you are shooting at, the ammunition you plan to use and your optics.

Quote HistoryQuoted: So most of my shooting is from 50-300 with a carbine. Seems that the 36 yard zero has less deviation than the 50. 50 is very similar until you get into longer ranges. At 300 your having to apply quite a bit of hold over. FYI not being an ass or anything, serious question. Most people seem to like 50. I feel the 36 yard zero is more 'new school' than either too so probably some newer shooters may not have heard of it and then you have the die hards like me that wont change 300 you have to hold a little high but its not so bad. I can do it with irons if I really try. With my MK18 and ELCAN its almost like cheating even at 300 yards, but then again it has a BDC(which is why the 100 yard zero for it) I do take some things into consideration. Like my Garand should I ever feel to mess with the sights I would sight it in per whatever it says so I could also use the BDC dial. Im willing to bet its a 100 yard zero |

A 36yd zero for a 20” M16 with only irons? Yeah I’ll buy that.
A 36yd zero for a RDS/LPVO equipped 10.5-16” AR? Bleh. I think context matters. It depends on what you’re using and what you’re doing with it. |

With dead hold optics I like 50-60ish. Basically whatever keeps the bullet within the dot the furthest range. Usually with something like an Aimpoint and the average carbine that works out to about a 100m zero hold on the top edge of the dot, and about 200m before it drops below the bottom edge of the dot.
I have enough rifles that if I’m shooting further than that, I’m using a more appropriate rifle for the job with a BDC or external turrets. |

Doesn't matter as long as you know the holds. The 30 makes sense to me for targets 0-300m.

It depends on your barrel length, ammo choice, maximum acceptable target size, and anticipated engagement ranges.
The best zero for an A2 is going to be different from an M4, which is going to be different than a 10.5" SBR. The "odd" zeroes are about making combat accurate engagement at the greatest variety of ranges without having to monkey with the sights. |

I own a range finder and I'm not stuck only using ranges. I zero most my optics at 100. I've been playing with a 36y on a RDS equipped 11.5" AR. Its quick and easy for even reduced sized silhouettes out to 300y.

I can't tell you it's dumb.
All my AR's either have irons only or red dots (with iron backups). I site them all in dead nuts at 100 yards. With very, very, minimal thinking I can hit my 6" steel plate from 50 out to 200 all day err day .... so easy it's boring sometimes ETA - you have me interested though and I will try the 36" deal on a rifle I am finishing now |

Just becuase you have a 36 yd zero doesn't mean you have to shoot at 36 yards to adjust your sights. You do the math. .72 inches low at 25 works in general. It's pretty close to the battle sight setting I got used to with M1 and M1a. Zero at 36 and back on at about 275. From a practical usage perspective, it's one hell of a lot easier to hit something by holding under it than holding over it and obscuring it with your sights. Doesn't matter as much with dots or crosshairs(unless you're shooting a German 3 post). |

I think the 36yd zero is good if your location is in west TX where you can see targets long distance like Afghanistan. Personally since I'm in south TX and it's thick with tall brush so I like the 50yd zero, a lot tighter up to 200yds and chances of actually coming across a clearing over 300yds down here is going to be rare unless it's a fence line.
And also, my range is 200yds max so that helps with my choice. 
And as others said, I also like my magnified optics zeroed at 100. |

depends on the BC and velocity from your rifle.... I fluctuate my zero based on what works best for the rifle, round and optic I'm using.
The primary arms I'm running in my avatar worked best with a 45 hard zero but my current optic (trijicon accupower 1-8) makes more sense with a 100 yard zero. I can make fairly precise / quick shots out to 500 with very little thought, with a 50 yard zero the subtensions were all screwy.

The rifles with RDS where I cant even resolve that fine of a POI (4-6moa dot lol), will be fine with a 36y and are considerably faster to employ |

Most of the time with "normal" cartridges in normal barrel lengths, a 100 yard zero is good enough to shoot anything closer than 100 yards at aim point, and good enough to simply hold at 200 yards at aim point(2.5" low), and with a bit of hold (+4") good enough for 300 yards.
Thus a 100 yard zero is good enough for anything where you have to aim and fire quickly. For things farther away, dialing of the scope is most reasonable. |

It's not dumb.
That's how I do my hog hunting rifle, and it works pretty much perfectly for my normal engagement ranges. I'd never heard of a 36 yard zero at the time, but when I started shooting the 6.5G I played around with a ballistics calculator for an afternoon and decided on a 38 yard zero for my particular hunting round

I have always used the 36 yard to get on paper. The outdoor range I belong to has a 300 yard range, so I verify/adjust there and check it every few months. If I want to be more precise through various ranges I get out one of the bolt guns.

I've seen these printed out and put inside rear flip caps. I personally also like to dope the rifle out under 100y if I'm running a 100 zero. So another column or a /.. for example 325 / 75 to give me my 75 y hold over. Its especially helpful down at 10-15 where your holdover is often down near your 700-800y holdover Quote HistoryQuoted:

People tend to zero at the distance their range allows or that their favorite instructor/youtube personality advocates. I prefer to use a 100 meters zero since it limits holdoffs and is most practical for the type of carbine work I see myself doing; though we us a 50 meter zero at work. Regardless of the zero a person chooses most drop the ball because they dont refine the zero on the far end and dont truely know where their rounds are impacting at 2-300 meters.
