7 Repeat steps 5 and 6 until all shots are on target.

What is a Second Focal Plane Scope?

A second focal plane scope (SFP) is a type of rifle scope that has the reticle located behind the second focal plane (FP). This means that the reticle’s size and position do not change as you zoom in or out, unlike with a first focal plane (FFP) scope.

SFP scopes are typically less expensive than FFP scopes, and they are often preferred by hunters and target shooters who do not need the extra precision of an FFP scope. However, SFP scopes can be more difficult to use for long-range shooting, as the reticle will appear to grow larger as you zoom in, making it more difficult to make precise shots.

How to Zero a Second Focal Plane Scope

Zeroing a second focal plane scope is a relatively simple process, but it is important to follow the steps carefully in order to achieve accurate results.

Step 1: Determine the Scope’s Zero Stop

The first step is to determine the scope’s zero stop. This is the point at which the reticle is aligned with the point of impact of the bullet. To do this, you will need to shoot a group of shots at a target that is at a known distance.

Once you have shot your group of shots, you will need to measure the distance from the center of the group to the point of impact. This measurement will be your scope’s zero stop.

Step 2: Mount the Scope on the Rifle

Once you have determined the scope’s zero stop, you can mount it on the rifle. Make sure that the scope is mounted securely and that it is aligned properly with the bore of the rifle.

Step 3: Adjust the Scope’s Windage and Elevation Turrets

Now that the scope is mounted, you can begin to adjust the windage and elevation turrets. To do this, you will need to shoot a group of shots at a target that is at a known distance.

Once you have shot your group of shots, you will need to adjust the windage and elevation turrets so that the reticle is aligned with the point of impact.

To adjust the windage turret, you will need to turn the turret clockwise to move the reticle to the right and counterclockwise to move the reticle to the left.

To adjust the elevation turret, you will need to turn the turret clockwise to move the reticle up and counterclockwise to move the reticle down.

Step 4: Verify the Scope’s Zero

Once you have adjusted the windage and elevation turrets, you will need to verify the scope’s zero. To do this, you will need to shoot a group of shots at a target that is at a known distance.

If the reticle is still aligned with the point of impact, then the scope is zeroed. If the reticle is not aligned with the point of impact, then you will need to adjust the windage and elevation turrets again.

Zeroing a second focal plane scope is a relatively simple process, but it is important to follow the steps carefully in order to achieve accurate results. By following the steps in this guide, you can easily zero your second focal plane scope and be on your way to making accurate shots.

How to Zero a Second Focal Plane Scope

Zeroing a second focal plane scope is a relatively simple process, but it is important to do it correctly in order to ensure that your scope is properly sighted in.

The following steps will walk you through the process of zeroing a second focal plane scope:

1. Mount the scope to your rifle. Make sure that the scope is securely mounted to the rifle and that it is properly aligned.
2. Adjust the scope’s parallax setting. The parallax setting on a second focal plane scope is used to correct for the parallax error that occurs when the shooter’s eye is not directly in line with the optical axis of the scope. To adjust the parallax setting, look through the scope at a distant object and rotate the parallax adjustment knob until the object appears to be in focus.
3. Set the scope’s reticle to the correct height. The reticle on a second focal plane scope is located in the second focal plane, which means that its size does not change as the magnification is adjusted. To set the reticle to the correct height, look through the scope at a target at a known distance and adjust the reticle until it is centered on the target.
4. Zero the scope. To zero the scope, shoot a group of shots at a target at a known distance. Once you have fired the group of shots, adjust the scope’s windage and elevation turrets until the group of shots is centered on the target.

Once you have zeroed the scope, you should test it by shooting another group of shots at the target. If the group of shots is still centered on the target, then the scope is properly zeroed. If the group of shots is not centered on the target, then you will need to adjust the scope’s windage and elevation turrets again until the group of shots is centered on the target.

Tips for Zeroing a Second Focal Plane Scope

Here are a few tips for zeroing a second focal plane scope:

  • Use a solid rest. A solid rest will help to stabilize the rifle and ensure that the shots are accurate.
  • Shoot at a known distance. Shooting at a known distance will help you to determine how much to adjust the scope’s windage and elevation turrets.
  • Use the right ammunition. Make sure that you are using the same type of ammunition that you will be using when you are hunting or shooting targets.
  • Take your time. Zeroing a scope can take some time, so don’t rush the process.

Common Problems with Zeroing a Second Focal Plane Scope

There are a few common problems that can occur when zeroing a second focal plane scope. Here are a few of the most common problems and how to troubleshoot them:

  • The scope is not parallax-adjustable. If the scope is not parallax-adjustable, you will not be able to correct for the parallax error. To fix this problem, you will need to purchase a scope that is parallax-adjustable.
  • The scope’s reticle is too thick. If the scope’s reticle is too thick, it can make it difficult to see the target. To fix this problem, you can try using a scope with a thinner reticle or you can try adjusting the reticle’s brightness.
  • The scope’s reticle is too bright. If the scope’s reticle is too bright, it can make it difficult to see the target. To fix this problem, you can try adjusting the reticle’s brightness or you can try using a scope with a dimmer reticle.

Zeroing a second focal plane scope can be a relatively simple process, but it is important to do it correctly in order to ensure that your scope is properly sighted in. By following the steps in this guide, you can zero your second focal plane scope quickly and easily.

How do I zero a second focal plane scope?

1. Set up your rifle and scope. Make sure your rifle is properly sighted in and that the scope is mounted securely.
2. Find a target at a known distance. The target should be at least 100 yards away.
3. Adjust the scope’s elevation turret. Turn the elevation turret clockwise to raise the point of impact and counterclockwise to lower it.
4. Fire a shot at the target. Observe where the bullet hits the target.
5. Adjust the scope’s windage turret. Turn the windage turret clockwise to move the point of impact to the left and counterclockwise to move it to the right.
6. Fire another shot at the target. Observe where the bullet hits the target.
7. Repeat steps 5 and 6 until the point of impact is centered on the target.

What is the difference between a first focal plane scope and a second focal plane scope?

A first focal plane scope (FFP) is a type of rifle scope in which the reticle is located in the first focal plane of the scope. This means that the reticle’s size and position relative to the target remain constant regardless of the magnification setting. A second focal plane scope (SFP) is a type of rifle scope in which the reticle is located in the second focal plane of the scope. This means that the reticle’s size and position relative to the target change as the magnification setting is changed.

Which type of scope is better, a first focal plane scope or a second focal plane scope?

There is no definitive answer to this question, as the best type of scope for you will depend on your individual needs and preferences. FFP scopes are generally considered to be more precise, as the reticle’s size and position relative to the target remain constant regardless of the magnification setting. However, SFP scopes are often less expensive and easier to use. Ultimately, the best way to decide which type of scope is right for you is to try out both types and see which one you prefer.

What are the advantages of using a second focal plane scope?

  • Less expensive: SFP scopes are often less expensive than FFP scopes.
  • Easier to use: SFP scopes are often easier to use, as the reticle does not change size or position as the magnification setting is changed.
  • Better for long-range shooting: SFP scopes are often better for long-range shooting, as the reticle remains sharp at high magnification settings.

What are the disadvantages of using a second focal plane scope?

  • Less precise: SFP scopes are generally less precise than FFP scopes, as the reticle’s size and position relative to the target change as the magnification setting is changed.
  • Less versatile: SFP scopes are less versatile than FFP scopes, as they cannot be used for both close-range and long-range shooting.

How do I adjust the parallax on a second focal plane scope?

The parallax adjustment on a second focal plane scope is located on the side of the scope, near the eyepiece. To adjust the parallax, turn the knob clockwise to move the reticle closer to the target and counterclockwise to move it further away.

What is parallax error?

Parallax error is a type of optical error that occurs when the object being viewed and the reticle are not in the same focal plane. This can cause the reticle to appear to be in a different position relative to the object, which can lead to inaccurate shooting.

How can I avoid parallax error?

There are a few things you can do to avoid parallax error:

  • Make sure that the object being viewed and the reticle are in the same focal plane.
  • Use a scope with a high-quality optical system.
  • Adjust the parallax setting on the scope so that the reticle is in the same position relative to the object, regardless of the distance to the object.

What are some common mistakes people make when zeroing a second focal plane scope?

  • Not using a proper target.
  • Not using the correct ammunition.
  • Not following the correct steps.
  • Not being patient.
