Question about zeroing scope

[chiburi]

Hi all,

Took my boy out the other day with his MP 15-22, that rifle is wonderful. he loves it!

Well, I realized my eyes are going, as the Sightmark 1/5 - 5x40mm scope appeared to work for him, but I couldn't see the holes in the target at 50 yards.

Thanks to all (from another thread) who recommended the MP 15-22. I think we put about 300 rounds through it, and were flawlessly every time. This weekend going to shoot the AR15 (me) and he'll have his trusty gun - they look and "act" very similarly.

Anyway, on to my question. I was trying to zero in the scope, and it just took forever (1/4moa click-turns on it). Anyway, I was under the impression the knob on the top of the was for moving the reticle up and down, while the knob on the side of the scope was for left and right adjustments.

Yes, I would have read the manual if the dumb box had come with one, so I guessed from my old days with scopes 30 years ago (when I was 10).

Anyway, is there a thread floating around here indicating the general "how to" of scopes / alignment? I could have sworn the knob on top was for up and down elevation, with the side knob for side-to-side / wind. thanks all!

I must have turned the knob from -0- to about 7 to finally get it sighted, but I think I'm missing something.

thanks again, yep - still a newbie (took a heatious from guns for 25 years!)

What type of scope are you using? Make/model? You can probably find the manual online.

The top knob should be for elevation. When you look at the dial it should indicate "up" and an arrow for which way to turn it. "Up" means, move the point of impact up.
The scope "should" come from the factory with the dials centered. None of the ones I have bought have been. 7 turns may or may not be a lot.
I can't see holes in a black target so I print targets that just have skinny black circles or a scrap paper with a small (~1") solid black dot for sighting in.

ok, this thing is working opposite. Very weird!

Is your scope 90 degress off? The windage should be on the right side (looking from behind the rifle in the shooting position) and elevation on top.

[QUOTE=freonr22;4713045]what scope? is it a snowwis? like this one?



just poking at you here is a good read

Hi,

No, it's a SightMark (mentioned in the first post) a 1.5-5x30mm. So, you guessed it, it was delivered in the same fashion as the pics - so the knob on top is the wind, and the one on the LEFT is elevation. Funny, not sure why they would have put it in the rings and delivered it this way! Thanks, that solves my issue. Man, do I feel like a dumb---.

So, now that it's on, I turn the knob to the "Right" and the crosshairs go left. When I turn the knob to go "up" it brings the reticle down.......

haha, that is great!

to the OP, print out one of these targets to help you sight-in... it makes it easier at distance:

there are other targets on that site as well, if you want a different pattern.

U have the scope on wrong. the knob for r to left should be on the side not the top.
The dot that is aligned with the magnification number 5 should be visible from the top not the side.
When you go to sight in since it may be skewed crazy right now, use a HUGE target and shoot groups of 4

thank you!

Here's a bullet saving tip to zero your scope. Place a soda can or something of similiar size on the ground 25 yds away and set the scope to its minimum magnification. Shoot at the can and you will be able to see if the bullet is high/low and left/right. Adjust your scope accordingly until you can hit the can. Then move to a target, adjust your magnification to maximum to fine tune your zero.

Remember if your scope has 1/4 moa adjustments per click that means 1/4" per click at 100 yds, 1/8" at 50 yds and 1/16" @ 25 yds. So to move the bullet impact 1" at 25 yds will take 16 clicks. Good luck.

I picked up a cheap laser boresighter for like $30 that I just toss in my bag. It's a "cheap" way to get your scope dialed in to at least hit paper on the first range visit. Moreso for larger calibers than .22LR though.

Gridded targets of whatever flavor are the way to do it though... makes it a LOT easier to be able to see what adjustments you need from your bench position. On a good day, you can zero it all out in maybe 2-3 groups of 3 shots each.

Some people claim they can do the zero in 2 shots total, but that requires a complete rest setup, or someone who is rock stable with holding the rifle steady after one shot and then adjusting the sight to line up with the first bullet hole. I doubt most people can do that reliably... well maybe Izzy can...

No, Izzy can't. Well maybe.

did you get things fixed?

The learning curve blues.

That's almost as bad as forgetting to turn the fuel tank switch on for your dirt bike. Of course it only happens when everybody is around. Delete the incriminating photos and ask that the thread be cancelled. Case solved by Pennys Dad. Nice work!
