Once you have mounted a rifle scope on your rifle, you need to ensure that everything is adjusted properly. The first thing you need to look for is whether the scope is well-seated on your rifle or not. Now, you need to look for the scope rings to make sure they are properly placed at the scope mounting base. Also, you need to make sure that there is no sort of movements at the scope mounting base and the scope rings.
When you have ensured these things, you need to take a look at the reticle and make sure that you can focus the reticle in a suitable way. What you need to do here is to ensure that the cross-hairs at the reticle is well-focused. In case the cross-hairs aren’t in focus, you should point your rifle scope towards the sky and place your eye to another direction focusing on a certain object for a while so that you will have complete attention towards it. Now, you need to look through your rifle scope by turning back and make sure that the view in the reticle isn’t blurry.
The exact thing that happens here is that your eye takes a quick judgment of what you see through your rifle scope. While looking at the reticle, your eyes will start focusing and adjusting themselves. However, if you find a blurry image, you might have to look at the end of your shooting area of your rifle and adjust the scope diopter properly. You need to keep adjusting the diopter until the reticle stops showing a blurry image which means it is well-focused.
The next thing you need to be doing is to perform boresighting. To do so, you need to ensure that the rifle isn’t loaded. The barrel also has to be unobstructed. You should the rifle’s bolt and place the rifle in a secure way pointing towards the down range.
Now, you need to stay behind your rifle and keep looking through the bore for centering the target. You’ve to move your rifle properly while doing so. Then, you need to adjust your rifle scope so that you can center the reticle towards the same target without moving the rifle from its original location.
At this period, the turret located at the upper part of the scope will adjust the elevation of the reticle and the one at the side will adjust the left and right part of the reticle. While doing so, the boresight shouldn’t be very accurate, your rifle should at least be able to shoot the target at a 100-yard distance.
For boresighting, using a laser boresight and placing it at the rifle’s chamber can also be an alternative method. While doing so, you just have to make sure that the reticle is centered towards your target properly. Using a laser boresight can make your entire work easier, but using the manual method as mentioned above will help you in improving your boresighting skills.
Zeroing The Scope At 100 Yards
Once you have boresighted your rifle, you can get started with the zeroing process of your rifle scope. Before zeroing your rifle scope, you need to ensure that you have an ammunition suitable with your rifle. If you are using a different and incompatible ammunition for your rifle, your every shot will be shooting in improper targets away from your exact target. You won’t be able to shoot where you want even by zeroing your rifle scope.
How to Get Started?
When you are thinking about zeroing your rifle scope at 100 yards, it might be thinking about using your rifle for hunting purposes. Zeroing your rifle can be difficult, but if you are sure about proper equipments with your rifle, you can easily perform the entire process. You might want to use an easier grid format to try out a zero target before getting onto the main point. Doing so can help you detect your current adjustments. You can later move on to the bulls-eye target. While zeroing your rifle scope, you have to utilize your rifle rest object such as sandbags so that you will have a proper area to shoot at the target precisely. Using your muscles to support your rifle while zeroing the scope might result in getting less accurate results.
When you are in a proper spot to zero your rifle scope, you might want to shoot the first group of around 3-4 shots with your rifle pointing towards the center of your target at 100 yards. While firing, you will be able to detect bullet holes in the target area with the help of your scope. But, this isn’t the end. You need to keep aiming your rifle towards the bulls-eye without changing the aimed spot. Maybe you wouldn’t hit the bulls-eye at your first shot, but when you keep trying, you will certainly be able to shoot at the exact same spot.
Adjusting Scope With Tryout Result
Now that you have thrown away some shots from your first group, you can look at the target spot and measure the center of your bullet holes to the bulls-eye target. When you have the measurement, you need to adjust your rifle scope properly. You might be using a rifle scope having the adjustment of 1/4 MOA since this is the same case for most scopes available out there. While zeroing your rifle at 100 yards, 1 click will turn over the impact zone of your bullet by 0.25 inches. At this distance, there needs to be 2 clicks left and 4 clicks down with your rifle scope.
Adjusting Bullet Impact With Turret
The bullet’s impact can be elevated with the help of turret above your rifle scope, whereas to move it left and right, the turret on the scope’s side will be helpful. If you want to know proper direction where you need to turn over your rifle scope, you can just look at the scope to find a printed text at the turret with proper information. During our research with a certain rifle scope, we had to turn the turret clockwise to move the bullet’s impact towards the upper or lower region. What you need to do with your turret really depends on the type and brand of scope you are using. You don’t need to worry about it since you will be able to find enough information at the printed region on your turret.
How About An Example
Let’s look at an example! Suppose the bullet impact hit 1″ towards the right and 0.5″ towards the lower region. This means you need to turn the top turret 4 clicks clockwise and the side turret 16 clicks anti-clockwise so that you will be able to move the bullet’s impact towards the bulls-eye target (up and left).
The Final Step of Zeroing
When you are zeroing your rifle scope at 100 yards, the movement of your bullet’s impact towards the left and right should be totally accurate. It isn’t mandatory for the case of elevation of your bullet’s impact at this range. When you zero your rifle scope at 100 yards and shoot at a shorter distance while hunting, it might be easier for you to adjust the scope properly to make the bullet hit the exact target spot.
When you have adjusted the turrets properly, you can shoot a few shots at the end to make sure every adjustment are done perfectly. If the bullets hit at the bulls-eye target, you have successfully zeroed your rifle scope at 100 yards. If the bullet holes aren’t in your target spot yet, you might want to perform some essential adjustments with proper measurement and try firing a few shots again at the target. You can continue doing so until your bullet holes appear the exact same spot where you have aimed at.
When you are ready to go for hunting the next time, your rifle scope is likely to be zeroed already unless you had dropped or damaged it the last time. However, looking at your rifle scope every time you go for hunting can help you ensure whether the rifle scope is properly zeroed or not. You also need to make sure all the screws are properly tightened before going for hunting the next time. You might also want to try out throwing a few shots to be sure about it.
