| Hello I am about to zero my Aimpoint T-1 and I am wandering where I should start. At what range should I zero 25 yards or 50 yards to be able to shoot out to 300 yards from my zero? |

Do a Google search for the 100y Zero 25 yard targets posted on this site: - print targets out - set them up at 25y - shoot and adjust at that range until poi is where it needs to be - test at 100y - 300y will have about a 12" holdover with a 100y zero (xm193 ammo) - memorize these holdovers - 5y, 50y, 200y, 250y, 300y, 350y, 400y - ignore the 50y zero folks...you're done |

50 will be much better at 300 since a 25 zero will put you around 10" high at 300 yards with the 50 being around 6" low at 300. Quoted:

General consensus is that a 50 yard zero is the sweet spot. You will get hits aiming center mass from 25-300 yards with minimal holdover. Also at 200 yards it's poa/poi. |

OP, I have three carbines with T-1's in them. Don't focus on the 300y need, read the advantages of a 100y zero vs a 50y and how that translates to variable distances.
The 50 yarders came in strong (would actually be my 2nd choice), but for combat/ hog -coyote hunting the 100y wins |

Here are the zero targets from Travis Haley's adaptive carbine video. 50 is left, 100 middle, 300 right http://i.imgur.com/InA6GZv.jpg Haley is good, but these are simply wrong. It's been discussed before. The 100y zero yields NO shots above the 100y shot. 50y shots are 1" low at 100y. The bullet travel levels out at 100, rises maybe a .02" at 110, then gravity takes its toll. This demonstration is wrong. |

I don't see how it could be wrong if he tested each zero at each distance. |

The 50 / 200 yard zero is the sweet spot as said above. You will be hitting in the kill zone from 0 to 300 yards. +1 Here you go, OP: Download this target here. Aim for the red, and adjust so rounds hit the gray bullseye, and you're good for a 50/200 zero. This is the target I use for my RDS and it works!

I don't see how it could be wrong if he tested each zero at each distance. You can search for it in Google or think logically. The bullet takes an asymptotic course. It begins to rise to meet the 100y for its zero and then gravity takes over. How would it be high at 25Y? has it already begin a downward slope to meet 100? No. A 100y zero starts rising at 25y (actually, as soon as it leaves the barrel) and 50y to kiss 100y, goes barely above 100y for a slight distance and then begins to fall again. Do a search on the hundreds of graphs showing the 100y zero bullet path. Haley is spot on with a lot he says and does. He was off for this video. EDIT: The above post seems crass...forgive me. It is true that no distance, with a 100y zero, has a high POI before or beyond 100y for the 5.56 cartridge. |

I wonder what happened with Haley's demonstration. Sucks they didn't fix it before putting out the video. |

Now if hailey had put a sticker or target to aim at on the guys chest his results would have been more accurate |
