Dead on, PezBoy! Who the hell are you? Thanks. I owe you.

Used your hold-overs, after zeroing with the 77gr, on Friday. They were right on. Surprisingly close to M193, actually. Thanks for your service.

Wow. This is crazy good stuff you have here.
Thanks for the effort!!!!! |
|

this is an outstanding thread. thank you so much for the wealth of info.
if i have a nightforce with an FC3G reticle, what's the closest approximation to the data here? they recommend a 200 yard zero and i'd be using M193 / M855 out of a 16 inch barrel. the reticle is supposedly optimized for most 5.56 ammo. forgive my ignorance as i'm new to this and i'm trying to get up to speed as quickly as possible. http://nightforceoptics.com/sites/default/files/FC3G_Reticle_Sheet_Final.pdf |

Not sure the tool you are using, but I was trying to back out from my ballistics calculator which of the smaller dots to use for extremely close shots (< 10 yds) to account for the sight over bore off set. Any guess? I was thinking just based on how it looks through the reticle that perhaps the bottom of the chevron. |

Do kids still play Cops and Robbers, or are they just taught both are equally bad and given a participation ribbon after a rousing game of scoreless Everyone's a Winner Ball? - BehindBlueI's

I never thought about that before, so I just did a quick experiment. I put two lines 2.6" apart (the bullet distance from the POA at 3m with a 100m zero) and aimed my TA02 at it from 3m away. The bottom line was more than twice as far from the 100m mark as the 600m mark. It ended up being close to a match from about 10m away. This is also about where my ballistic calculator says the 600m near zero would be.

Seems like that is a lot farther than I thought. At 7yds it match up with what you said for the ACOG, and the ACSS was basically at the bottom of the horse shoe. This was holding over at the top of a standard IPSC target to get an "A" zone hit, which is typical for my rifels from some of the shooting I've done. |

thank you, I'll get back to you.
I shoot 600Y with an 18" and a bdc reticle that I match reloads to I'll see if I can put a hole somewhere in one of those giant 600Y targets sometime..... thanks again , folks like you make the world a better place Dustin |

You're welcome. Let me know if it needs adjusted or you need anything else.

Pezboytate,
Would you be interested in posting the reticle drawings for the Norden Performance 1-6 Combat Rifle Scope (CRS)? If yes, please contact me. Thanks Ed Verdugo 951 845 9838 grscinc@gmail .com |

I can't figure out why. They are showing up in my Photobucket, I even uploaded them again with a different file name. I don't know if it is an ar15.com problem or photobucket problem.

This thread is fantastic! M16 targets will be great for referencing with my Delta HBAR.
Any possibility of M80 out of a 16" with a 50 yard zero for us AR-10 platform folks? EOTech reticle would be my preferred one. |

I need to find solid data on M80 first and I should probably re-upload everything since there are some errors.I'll do a red dot first and then the Eotech later. |

@pezboytate
Can you do a computation for M855A1? 50m-500m? Combat EIC Target (Xring is slightly higher than COM) 265y Zero TA01 and TA31FM150RCO - M4 - standard sight height - also, M16A4 (20" barrel with rifle sights) BC of .292 MV 3149 Projectile length of .995" 62gr |

Driving up, parking and shooting over the side of the truck until everyone on your team has a serious head wound is probably not the best plan. - Low-cap

What is your POA mark on the reticle for the 265 y zero? View Quote Yes, that is correct target. At 200y, I hold the center of my TA01 (or tip of the chevron on the TA31) on the bottom of the 5 ring. At 300, I hold the top of the 5 ring. I really appreciate the work. I have been struggling on how to have the target sized accurately at that range. |

Could I trouble you to do a computation for me? I am teaching a new shooter and she's not understanding the purpose of hold overs/unders. She has a 14.7" barrel with M193 and carbine iron sights. We are using Alt-C targets so Army qualification targets would be great. I would totally print these out and hang them in our house so she has to look at them.
Edit: 250m zero, as per A1 sight system. |

I can also send you a PDF of that and the ALT-C that has the regular black silhouettes with an additional offset outline where their bullets should hit when aiming at the correct spot. |
