## What is Boresighter?

You get a new rifle and optics and head to the range. You aimed the target at 100 yard and pull the trigger, so exciting! But wait, where is the bullet hole? You set the target back to 50 yard, shot again. Still, there is no bullet hole. You move the target back to 25 yard and finally on the paper. It's 5 inch high and 6 inch to the left, no wonder. So, how do you adjust your scope? Things maybe a little complicated, you adjust the scope with you best guess, and shoot the 100 yard target again. Well, still no bullet hole. You get back to short range and try again, finally, you hit the bullseye at 100 yard, but your ammo box was already half empty.

Sound familiar? then this app is for you. You can aim your rifle at target at 25 or even 15 yards, pull the trigger, tell the app where the point of impact is, the app will tell you how to adjust your scope to archive zero at 100, 200 or even 300 yards! The app uses built-in ballistic data to give you the best guess and it will save you a lot of ammo.

This app is not another ballistic calculator, it was designed especially for sighting in new rifle and optics and extremely easy to use. The ballistic data is from the most popular standard factory loads, 168 grain Federal Gold Medal Match for example. They may not the exact match with your firearm and ammo configuration, but should be close enough get you on paper really quick.
