How To Sight In A Rifle Scope At Yards?

Sighting in a rifle scope at close distances is easy. You’ll need to use a laser rangefinder to measure the distance to your target. Then you’ll need to adjust the elevation of the scope until you get the right amount of magnification.

Tools for the job

1. Screwdrivers are tools used to tighten or loosen screws.
2. A rifle scope is an optical device used to aim a weapon.
3. A turret is a circular part of a gun barrel that rotates around the axis of the bore.
4. A cap is a metal cover over a hole.
5. A windage is the amount by which a bullet is off target when fired.
6. An elevation is the angle of the barrel relative to horizontal.
7. A MOA is the distance a bullet travels in one minute of arc.

You need to mark each shot on the paper. Then you need to put a bullet hole in the center of each square. After that, you need to make sure that every shot hits within the target area.

How to Sight in a Riflescope at Yards?

• Safety first! Always wear safety gear when shooting. Don’t point your gun at anything you don’t want to shoot. Keep your fingers off the trigger until you’re ready to pull it. Keep your weapon pointed at safe until you’re ready to shoot.
• Step 2: Hang your target 25 yards away from the shooting line. Make sure you have an unobstructed view of your target. Don’t tilt your target. If outdoors, use cardboard and staples to secure it. If it’s windy, wait until it calms down.
• Step 3 (Fire) – Aim about one inch above the center of the target to ensure accuracy. You should take your time firing, as each shot counts.
• The center of my round grouping should be 3 horizontal and 2 vertical. I subtracted 1 from each square because I want to know how many squares there are to the center.
• Step 5 (Make Adjustments) – Remove the caps from the windage and elevation turrets from your riflescopes. Your rifle should be 1 click1 inch on your paper target. Start with the elevation turret and turn the knob until it makes the number of clicks you wrote down earlier.
• To adjust windage, you must first rotate the gun to the opposite side. Then step back and shoot two or three times, adjusting as needed.
• You need to make sure your rifle is accurate. Big game animals are dangerous, and you need to shoot them accurately.

Formulas for Adjustments

Most scopes have an adjustment of.25 inches per foot. This means that if you move 10 feet forward, you’ll be adjusting your scope by 0.25 x 10 2.5 inches.

You need to adjust your scope by 100/((distance to target in yards)/(100))inches. Then divide this number by ((number of inches of adjustment needed)/(inches per MOA at the given distance)). This gives you the number of clicks you need to make to get the correct adjustment.

Location

Shooting at night indoors can be difficult because there aren’t many lights to see by. Sighting in your rifle scope can be done at most ranges.

Be sure to check that your gun range can support the range you shoot at. Make sure you have enough room to position yourself properly. Don’t substitute practice shots for real ones. Practice slow and smooth, and smooth and fast.

What is Zeroing?

When you buy sights for your guns, you must adjust them to match POA and POI. You can’t just throw them onto your gun and expect a bullseye shot. This is called zeroing.

How does it work?

You need to first determine where bullets are impacting (POI). The best way to achieve that is by aiming at the middle of a large paper target, pulling the trigger, then recording where the round landed on the target. If the round landed high and right where you aimed, then you need to adjust the sight higher and right. This adjusts the point of impact down and right to match the bullet’s actual impact. You need the reticle to wind up on the exact spot where the bullet landed in the first place, or else you’ll be shooting yourself in the foot. The process is more complex than this, but we’re going to use visual aids to show you how it works.

MRAD turrets provide 0.1 mils (0.01 inches) of adjustment per click. How do we measure these angles in point of aim and impacts if we know our distance from the target? We need an instrument to measure these angles. A reticle can be used as such an instrument. Subtensions are the exposed knobs that control the elevation and windage of the reticle.

Milliradians measure distances by using units called mils. A milli-radian is an angle measured in degrees. In this case, the mils represent how much the POA needs to be adjusted to account for the distance.

Minute of angle is used to measure distance. One minute of angle (MOA) is equivalent to 1 inch at 100 yards. To adjust to 2 inches at 100 yards, you would need to move your aiming point up by 2 minutes of angle.

MOA is the more popular combination of reticles and turrets for most shooters, simply because it’s much easier to use. Calculations in mils are more difficult if you’re accustomed to the imperial system of measurements. Essentially, if you’re an American, then you enjoy inches, feet, and yards more than a centimeter and meter systems. The mil system was designed for calculating adjustments based upon the metric system.

Now we understand a point of aim, point of impact, and the effect of distance on both. We also know about the suspensions and turrets of scopes. We can now convert an angular measurement into scope adjustments by using the suspensions and turrets.

Scope Adjustment

All scopes adjust the position (point of aim) of the reticle (point of impact) with turrets. Some scopes have 3 turrets: one for windage adjustment (to left/right), one for altitude and range (up/down), and one for focusing.

You will only use 2 of them to zero, the other is for achieving clarity. For most scopes, 1/4-MOAR adjustment means each click moves POI 0.25 inches at 100 yards. For most scopes, 1/10-MRAd adjustment means 0.1 inches at 100 meters.

This scope’s reticle has 1/4 MOA tick marks. Our shot was 3 MOA right and two MOA high. That means we need to adjust our scope by three inches right and two inches up. On a quarter click, that’s twelve clicks right and eight clicks up.

Using our mil dots, we see the round land 4 mils left and four mils high. That translates into 3.6 inches left and 3.6 inches high. With 0.10-mil turrets, that means 40 clicks left and zero POA with POIs.
