ive read on here a few times, but i dont understand what passing the box test means and also read sweet spot, which i can only assume is the magnification and distance where the scope is the clearest, im new to this forum thing, this is only my second post and i would like to become more knowlegable on optics and how to use them to better benefit my hunting and shooting capabilities. Any help is greatly appreciated. Thanks.

box test is when once you've zeroed your scope, you use the turrets to move the impact. First you would move right by 4 clicks and shoot, then move it 4 clicks down and shoot, then 4 clicks left and shoot and finally 4 clicks up and shoot. there should be 4 holes in your target in the shape of a box and they should be about inch apart..... if your scope is set to 4 clicks per inch at 100 yds. Make sense?

A box test is to see if the adjustments of the scope are repeatable and reliable.
The "sweet spot" is usually referring the center of sight picture through the scope. This usually the best view through the scope, and the better the glass the larger the "sweet spot" is. Whereas lesser glass will have softer edges and maybe even some "milky" appearing glass.

For the box test I would move it alot more than just 4 or so clicks. Optimally if you really want to test your scopes adjustments you want to move them to extremes.
If it is a hunting scope that you just zero and leave it alone a box test is not really that important. If it is a scope that you will be spinning turrets a lot and that is a rifle where repeatability and accuracy is very important then you will need to box test it to make sure the adjustments are true and repeatable. Doing a box test at 25 to 50 yards is actually a really good idea. The closer you are to the target the more clicks it will take to move the POI a given amount. If 1 click is 1/4 moa at 100 yards then it would take 4 clicks at 25 yards to equal that 1/4 moa. Also you want to do your box test on paper that has box grid of some sort on it, so you can verify that it is moving exactly how much it is suppose to. So at 25 yards it would take 12 clicks to move it 1 moa. So if you can move it 3 or 4 moa then it would take 36 to 48 clicks to move it that much. That is going to test your scope much better than moving it just a little bit. It will also take some of the shooter error out of it as it is easier to shoot good groups at closer ranges. After that is done, I would still test it at 100 and 200 yards, just to re-verify everything. |

before running the grid tests turn your scope to the upmost setting and leave it for a few days, then when you run the box, any spring set will show up. a good alternative is to use a 9 dot test spread over 12 inch selecting the dots at random and using at least 3 shot groups, this will tell you if the entire spread of the scopes adjustment has shifted up or down. left or right.

Sorry guys. In my head i was thinking it would be good to move the poi at least 4 moa instead of just one. But thats not what i typed. I was doing it on my iphone so i did not reread my post. Thanks for correcting me
