If this is in the wrong section, feel free to move it. I dont access to a range that shoots further out past 100yards, so I hve to do some guess work here.

Specs on AR;

18" SS WOA 1/7twist, Free floated


Hornady 77gr BTHP Match

With my scope (SWFA SS 3-9 x 42) w/ mil dots, set at 100yard Zero.

The question;

Where will my rounds be at 200, 300 & 500yards.

Is this hornady custom loads or your own? do you have the velocity at muzzle and BC of the bullet. I can plug it into my ballistics calculator and give you a rough idea...

Its factory ammo. I just got the box, Apparently they have the ballistics posted on it in fine print. lol.

They are using a 200yrd zero though.

100yard = +1.9"

200yard = 0.0"

300yard = -8.3" < seriously, this big of a drop?

500yard = -49.3"

Muzzle 2790

That must be the same stuff Im using..lol Well out of my 20: Barrel i can tell you its pretty damn close to whats on the box. I to only have a 100 yard range so once I sight in for 100 yards I raise my point of impact up to hit 2 Inches above the bullseye. that puts you around the 1.9" at 100 yards on the box. i know when I had a chance to shoot a coyote at 300 yards across a old corn field I just put the crosshairs a smidge above its back and I drilled it right in the boiler .. so I hit about 8 inches below where I was aiming. Id sayits pretty close to whatthey say give or take a bit depending on your barrel lenght. I dont know if this helped ya at all. Heres what I came up with trying to get a rough estimate from my ballistics calculator.
