Absolutely correct. If you don't have access to a 100M range, you can calculate the appropriate offset and use any known fixed distance range to dial it in. Quote HistoryQuoted:

A few things I've noticed so far. His ACOG isn't 4x32. It has good eye relief because of that.
40 keep in mind each ACOG isn't only calibrated for a certain bullet, its also calibrated for a certain barrel length (velocity, = rate of drop) It won't matter at 300 and in though, double that distance it could start making a difference. Always zero at 100m. Can't tell you how many threads ive come across where the OP zerod at 50 yards. This makes the BDC useless. |

Inside a couple hundred the BDC is mostly completely interchangeable. My 31F shoots well enough with a 12.5” firing 77gr out to a couple hundred, for example. Past maybe 300, it’ll start to matter more and more.
You’re shooting 855 though, which is far from precision ammo. I’d imagine this becomes a balancing act between wanting mechanical precision with your ammo, and wanting your BDC to line up at range. In practice, this depends on whether you shoot mostly <300m or >300m. If the former, I’d use whatever ammo I wanted. If the latter, I’d use something close to the BDC. |

This thread....
You should be getting almost 0 moa out of your ta33, as long as it is mounted correctly and you are properly (repeatedly) sighting using it correctly (head alignment). You, your rifle and your ammunition will be the determining factors in accuracy, not the acog. Now, I don't really understand your question... are you asking if the BDC will match up "pretty close" with 55gr vs 62gr ammo? Because that's not accuracy. But yeah, the acog is designed to be pretty solid at minute of man, and you should have no problem up to 300m as long as you range reasonably, using either ammo type. All the guys saying 'you should expect this out of your acog'. You should expect basically zero affect on your accuracy due to the optic (almost zero moa). If you are getting a measurable effect, either the optic is broken or you are not practicing the fundamentals. |

OP, really depends how good of a shooter you are.
You have a gun set up to adapt to multiple situations well but not excel at any one thing, so don't expect precision results. Assuming you're a decent shooter at 100yds with a 4x ACOG and the aforementioned ammo you'll be doing good to keep everything inside 3-4" Swap the ACOG for a HPVO, and the bulk ammo for some match ammo and you'll know how accurate you/the rifle are. |

Ok, I will have to work on this. The ranges I go to have fixed distances and typically don't let you put stuff out. I guess I will just figure out what the difference is in my hold over inches and apply it to a 100 yard target. Basically aim for bullseye and correct the impact until it is at the difference.

OK guys check my math.
100 meters = 109.36 yards 9.36 yards = 336.96 inches Using Strelok Pro: 100.0 yard zero = D0.0 109.4 yard shot = U0.0 Basically Strelok Pro only goes to .1 and I need it to go to at least .01 so I know how many fractions of an inch to go up.

Inside 300m it really doesn’t matter what you use. At most, if you’re using a setup with a good bit more drop than the BDC (like my 12.5” shooting 77TMK), I’d zero it 1-1.5” high to split the difference and call it a day.

An optic doesn't effect a cartridge's accuracy, or even the rife's accuracy.
55gr and 62gr will be close to the ballistic reticle. 62gr will probably be closer but there are different variables that can change it. Don't forget to slap the ACOG after making an adjustment, or you may end up chasing your zero around for no reason |

I used mine on a 16" flat top with no issues at all. IIRC, I had to tweak my 100 yard zero just a hair to get it right on the money at 300, and the rest of the BDC should have been close enough per the old thread. Hits on steel always felt easy with the ACOG, and almost every time I let a new shooter try it, they had first round hits on steel at 300, which is a huge confidence booster! 
It is currently homeless, and I need to figure out which host I want it on next. |

@40xb I have been shooting a TA33 on a 14.5 inch rifle for 8 years now. In the optics forum an arfcommer did some painstaking research on where to zero your acog combining bullet weight and apprx velocities for the bdc to work correctly. With my 14.5 inch barrel, I zero at 50 and can hit uspsa/ipsc sized torso targets out to just over 500 yards nearly every shot with M193, using the BDC unless it's very windy. The Horseshoe/dot reticle is not a precision reticle but I can shoot 2-3 inch groups consistently at 100 yards.

There was a guy in the Precision Rifles forum arguing it was a "Precision Optic" for shooting at distance. He wouldn't back off the point either, so I suppose you should be able to do at least as well as good as a 32x-60x scope.

If you want to initially zero it at 25 then use a 25m bzo Target and the BDC for 300 as your poa/poi. You will be pretty damn close. Then verify it at 100 using the dot in the center of the horseshoe. I would also practice using the BDC at 200, 300, and 400 too if you have a range that accommodates it. Edit: I have 2 TA-33 and that’s how I initially zero them. One I never shot beyond 25m before I used it to clear all rifle targets at CWW 1. Someone also borrowed it and did the same. M193 55gr out of a 16” barrel. Its just ammo right?

Zeroed at 100m with the tip.of my 31F, on a 20" AR. Boringly reliable hits on man size steel at 500M with wolf 55. |

Interesting thread and gives me food for thought. I have a TA01 that I want to love on a 18” mid for longer-range work but I see no advantage over a traditional scope. Doubt I’d buy another one....

I have ARs in many calibers with RDS, Scopes, and now an ACOG. If I do another AR it will be a 10.5" pistol with a fixed carry handle and fixed FSB. |

This thread.... You should be getting almost 0 moa out of your ta33, as long as it is mounted correctly and you are properly (repeatedly) sighting using it correctly (head alignment). You, your rifle and your ammunition will be the determining factors in accuracy, not the acog. Now, I don't really understand your question... are you asking if the BDC will match up "pretty close" with 55gr vs 62gr ammo? Because that's not accuracy. But yeah, the acog is designed to be pretty solid at minute of man, and you should have no problem up to 300m as long as you range reasonably, using either ammo type. All the guys saying 'you should expect this out of your acog'. You should expect basically zero affect on your accuracy due to the optic (almost zero moa). If you are getting a measurable effect, either the optic is broken or you are not practicing the fundamentals. physics and knowing your hold. If you're looking for some more info about zeroing, you should learn about PBZ. Point blank zero. |

I've shot 2MOA groups out of an issued M16A4 with a TA01NSN at 500y.
Eye relief is bad, head position is critical, but they are capable of great accuracy. |

I take it then that the ACOG TA33/TA11 are still considered some of the best all around optics available? I had a green TA33 that I couldn't adjust to. The green washed out too easily and I'm looking for a red horse shoe.

I have the 7.62 Nato BDC and zero it for 77 grain SMKs. Mine has a green chevron. I can shoot a bit under 2 MOA with it at 100 yards, but struggle to get small groups. If I get another I will get a red horse shoe instead.
