Sight in help - 50 - 100 yards

[barnabus1999]

Beautiful day in the hills today. Trying to dial in a 1x8 optic on my Colt 6920.

50 yards looks decent photo attached. When I moved back to 100 yards things got messed up. Was shooting at least 2" high. I shot a few more rounds then got fustrated then onto mag dump (super fun when the gun is in the Bog tripod). Anyway shooting high the further away I get?! I'm confused someone share next step. I'm gonna start over with laser boresight and try again. Sight in at 75 or 100 yards maybe? What would have happened if I got closer? I got bored of testing and decided to have more fun. Where to go from here?

Zero for 100 yds on max magnification.

For mine it's .5" low at 50 and 1.5" low at 25 yds with a 100 yd zero.

 

[powermad]

Easy 25 yd sight in for 100 yard zero.
Dial it in at 25 yds and verify at 100.

Strelok+ has some nifty features for scopes.
Mines a SFP 1-8
At 25 yds on 1

At 25 yds on 8

That target image is nice thanks powermad. Now I can get a zero at 100 yards easy.

So closer than your zero distance you are generally going to shoot a bit higher I take it. I don't want to know why right now cause it seems backwards to me. Thats not making sense to me dang if I shot way furner out I would be raising the gun not lowering it grrr

No you shoot lower if your closer than your zero seems like

For mine it's .5" low at 50 and 1.5" low at 25 yds with a 100 yd zero.

Ill check out the smart ballistic calculator

The diagram above is starting to make sense. Always something to learn.

 

[powermad]

With a 100 yard zero everything is a hold over.

 

[powermad]

With the zero target you aim at the colored portion and your hits will be in the gray one.

To hit the colored target after zeroing you would hold 1.5" high.

 

[powermad]

The Strelok+ app shows the hold over or under that you would need.
Also gives the MOA needed if you are turning the turret.

 

[powermad]

Lately to conserve ammo I just bore sight at 25 yds and dial it in at 100.
I'm usually pretty close.

Easy enough with the Bog, pop in the upper with no BCG and sight in the bore then adjust the reticle.

nice group. this is what your supposed to do with an AR15. Zero at 50, it shoots 1-2inches high at 100 but it shoots zero again at 200 yards. This is the typical battle sight it. Hunters call it a Maximum Point Blank Range zero. Basically from - to a bit over 200yds you just aim dead on and will always be within 2" vertically (all other things being equal...).

Lots of personal preference here.

This is what I do as well. About 4" - 6" low at 300 yards as well. This has worked will for me at these ranges.

I use the 36yd zero that I found here https://www.vigilanceelite.com/blogs/vigilance-elite-blogs/36-yard-zero

 

[oremike]

My .223 is zeroed 2" high at 100 yds, my 45-70 is zeroed to point of aim at 100 yds. My 300 Win Mag when I get the time and it's pet load worked up will be zeroed 4" high @ 200 yds.

On a good note I think this means I can just use my crosshairs and be in at 50 yards good then at 100 yards I can use the inner circle ️ of the optic to measure down to the 100 yard mark

I barely know what MOA is but starting to make sense. That's what them lines are for huh huh

for MOA all you have to remember is your group size in inches at 100 yards.
1 inch group at 100 yards is a "1MOA" zero. Or, a 1inch group at 50 yards is a 2MOA zero..

anyways, what scope do you have?
