sighting in my scope question

rebs · April 27, 2012, 06:47 AM

I have a S&W Sport AR 15 and I mounted a Leupold 2 to 7 scope on it. I need to move the point of impact up 1" and to the left 4". On the scope adjustments it reads 0 to 7 and it also reads 2x7. the elevation has a U and a D, the windage has a L and R. But I don't see a MOA as to tell how much each click will change the point of impact.
What would you guys recommend ?

The and 2 and the 7 refer to the power settings of the scope.

Look at the adjustments for windage and elevation, there should be an arrow on them. Those arrows indicate which way the aiming point will move when the adjustment is turned. It will usually be something like an arrow with an R or arrow with a U.

There may be some index marks on the scope or it may just be a friction adjustment.

Best advice is to look a lot and make one adjustment at a time.

Dial in the windage, then work on the elevation.

If you are shooting at 100 yards, I would start with moving the elevation up 4 clicks and shoot to see where the group goes.

I am betting you have .25 MOA clicks. Then I would give it about 16 clicks to the left and shoot some more.

Other option is call Leupold.

Is this gun new? Is the scope new?

If so, there should be some manuals to look through to help you along.

In round numbers, one MOA is one inch at 100 yards, two inches at 200 yards, etc. The adjustments will be quarter-minute (quarter-inch at 100 yards) or half-minute (half-inch at 100 yards).

If quarter-minute, then, at 100 yards, move four clicks up and 16 clicks left. (If it doesn't "click", go by the marks on the dial and the index point.)

When sighting in, I shoot three-shot groups and move the center of the group. Trying to adjust after just one shot is an exercise in futility.

I went to Leupold and downloaded the manual,
Thank you for the replies, I appreciate it

rebs - what model Leupold do you have? What distance are you shooting?

Just my guess here, but is your scope a Rifleman model? If it is, it has a 1/2 MOA windage and elevation friction adjustment. Those .5, 1, 1.5...numbers would correspond to .5 inches, 1 inch, 1.5 inches and so forth at 100 yards.

Hope that helps.

You are exactly right, I called Leupold and then downloaded the manual. The one manual covers all their scopes.

Rebs, Go out and shoot three shots on a clean target. Move your scope any number of marks, doesn't matter. Remember what you moved and shoot three more rounds. Look and see how far the POI moved. Divide distance POI moved by the number of marks you adjusted your scope and you can figure out the MOA each mark moves your POI.

Example: Shoot three. Adjust scope left from 0 to 4 mark. Shoot three more. Group moves left 4". Divide 4" by 4 marks gives you 1 MOA/scope mark. Now all you need to do is measure from the last group to the bull, up and over, move your scope that many marks and shoot bullseyes!

Good luck.

Good deal man. Have fun and safe shooting.

A very easy way to sight in a scope is to shoot once and move the + to the spot where the bullet hit. The key in doing this is you have to have a good rest that will absolutely not let the gun move when adjusting the scope to where the bullet hit. I can sight in any properly mounted scope in under 5 shots using this method.

Here's what I do. At 25yds I take a blank piece of paper and put one 1" dot on it, mount rifle in rest and take one carefully aimed shot at the one dot on the paper now mount the rifle back in the rest and put the + back on the dot(where you aimed) ok here is the critical part with out moving the gun adjust the + to where the bullet hit if you do that correctly I guarantee you the next shot will hit the dot (where you aim) dead on at 25 is going to put you about 4-6" high at 100yds for most center-fire rounds so I usually adjust my elevation about 15 clicks down and I am usually pretty close when I take that first shot at 100yds.

Anyway thats how I cook my BBQ cook yours how you like it......lol

If some of you guys were driving from Atlanta to Dallas you'd go through Pittsburg to get there. This ain't rocket science, stop making it harder than it has to be.

Trying to adjust after just one shot is an exercise in futility.

At 50 yards a 2nd or 3rd shot is a waste of time and ammo. At that range a 2nd or 3rd shot will either be through the same hole or no more than 1/4" from the 1st and tells you nothing. At 100 yards a 2nd or 3rd shot will be no more than 1/2"-1" from the first.

All you need is 1 bullet hole through a piece of paper. A sheet of poster board is $.30 at Walmart. Put up a BIG piece of 30 cent paper with a 1-2" circle drawn in the center with a marker. If you can bore sight fine. If not, it is almost impossible to miss a target that large at 50 yards. Fire 1 shot. Even if you're a foot from the bull it is OK. If possible measure the distance both vertically and horizontally. If not, estimate, count clicks and adjust your scope. I you have a half way decent scope and if your mesurements are right you will be within 1" of the 50 yard bull if you decide to shoot a 2nd shot at 50 yards.

I go straight to 100 yards for the 2nd shot, but if you're not comfortable with this then fire a 2nd shot at 50 yards and re-adjust if necessary. At 100 and 200 yards I just use a 9" paper plate with a 1" aiming point in the center. After fring once at 100 yards I adjust if necessary and fire my 3rd shot at 200 yards. I make no attempt to fine tune anything at closer ranges. My only goal is to get on paper at 200 yards and I can do that with 3 shots from any scope sighted rifle even if I can't look through the bore or without using a bore sight tool.

Only after I'm on paper at 200 yards do I start shooting groups and fine tuning my rifle. You can have a rifle zeroed at 200 yards in 15 minutes and with no more than 4-6 rounds of ammo.

Even if I don't plan on shooting at 200 yards I like to fine tune my scopes windage at that range. Your scope may appear to be perfect at 100, but small windage errrors often don't show up until you shoot at longer distances.
