AccuScore SmartPhone Apps Help with Rifle Sight-In Process
Many folks struggle when they sight-in a scoped rifle for the first time. A very common mistake is clicking the turrets in the wrong direction. That’s frustrating and it wastes ammo. Another common problem occurs when people sight-in at a distance other than 100 yards. People sometimes struggle to figure out how many clicks they need to correct point of impact if they’re zeroing at 200, 250, or 300 yards.
To make the sight-in process more fool-proof, AccuScope has released two handy Apps for smart phone users. Whether used for initial sight-in or in-the-field adjustments, these smartphone Apps can get you zeroed quickly and reliably.
Using the Apps is easy. First, boresight the gun to get on paper. After the gun is fouled-in (so it is shooting normally) shoot a carefully aimed 3-shot group. Then go to the target and measure the vertical and horizontal distance from the 3-shot group center to your aiming point. Input those numbers into the App, along with your sight-in distance (from muzzle to target). The App then calculates exactly how many elevation and/or windage clicks you must crank into your scope to move point-of-impact to point of aim. Put in the specified clicks and then take a fourth shot to confirm your zero. The fourth shot should impact right on your point of aim (within the limits of the gun’s inherent accuracy.)
Given Murphy’s Law, a shooter can still mess things up if he inputs left clicks when the App calls for right clicks, or inputs down clicks when he needs up clicks. But as long as you look at the “R/L” and “Up/Down” labels on your turrets before spinning the knobs, you shouldn’t have any problems.
AccuScope is available in two versions, Standard and Premium. The $4.99 Standard version works for 1/4 MOA-click-value scopes. The $9.99 Premium version works with all scopes and any click values. The Premium version works with 1/8 MOA clicks, 1/4 MOA clicks, Metric clicks, or Milrad segment click values. So, if you have a scope with 1/8 MOA clicks, you’ll need the Premium version.

Product Tip by EdLongrange. We welcome reader submissions.Editor’s Comment: Does this App really provide a solution you can’t figure out yourself with simple arithmetic? No, but some math-challenged guys may find that the App prevents errors. Additionally, following the step-by-step process used by the App will probably help some shooters avoid confusion, and avoid wasting ammo clicking in the wrong directions.
Note however, that there is an even simpler way to zero, if you have a very solid front and rear rest that will hold the gun absolutely steady while you click. After bore-sighting, fire a couple rounds (with the same point of aim). Then place the rifle so the center of the cross-hairs is exactly on your original point of aim. Next, without disturbing the gun in any way, dial your turrets so that the center of the cross-hair moves over the center of your group. That’s it. You’re now zeroed (though you may want to repeat the process for confirmation). Again, this only works if the gun doesn’t shift one bit when you’re clicking. Having a helper steady the gun as you click the turrets will make this “no-math” method work more effectively.
