Rifle scopes, are sadly, just mechanical devices, and whether you like it or not, your scope will experience some failures over time of use.  Some parts will go loose or the entire thing will not hold its zero.  Hopefully, when an issue starts to take shape, it will reveal itself enough for you to recognize it.  Sometimes, it takes too long for a user to identify the source of inaccurate hits at once.  It can be because the POI’s change is slight or you’re still satisfied with the clarity of vision. 

But for everyone, it’s better to know things earlier than groping for answers when problems occur.  The information below can give you a little of the basics in this area of rifle use. 

Common Issues

While you may still be happy with your shooting results, it may be to your advantage if you know whether your scope needs checking (by the accuracy of your shots or group of shots), and whether or not the problem is scope-related, for advice, more easy to operate brand considered  vortex rifle scope in this review.  Here are common scope issues. 

  • You know you’re accurate with your loads, but the level of variance in POI from shot to shot is too large to get unnoticed.
  • The tracking is not even, whether you are going left and right, or up and down. 
  • The click inputs doesn’t match changes in the POI
  • You feel there are shots where the scope does not hold zero and the number of those shots is quite significant. 
  • Sometimes, the number of clicks exceeds expectations.  Make sure you have a good picture of the values you have had in the past. 
  • Check the reticle.  It may be shifting a little bit from the center.  Any shift is not hard to detect.
  • There’s a certain “feel” to note of when doing the clicks.  Anything that diverts from the regular “feel” should be investigated.  For example, there’s a kind of resistance force which you never felt before.  There’s also the felling of unevenness between two succeeding clicks.
  • Learn about the parallax because it is this one that does the sharpening of vision.  The moment you see some difficulty on setting the parallax, there must be a problem. 
  • Check controls like the turrets.  If they are wobbly or loose, they can significantly affect performance.
  • When the rifle moves you hear rattling sounds.  If you are unsure whether the sound is coming from the inside of the scope, disengage it from the rifle. 

Check the Case

The problem might be nothing that relates to the scope itself, but rather on the case where you keep it when not in use.  The best case is something that’s soft inside but rather hard on the outer cover.  Some people who use aluminum-sided case that has foam from egg crates inside reported it took them quite a deal of an effort every time they need to close it with the gun inside. 

That’s a case of side-loading that compromises the windage turret. The problem with this kind of foam is that it doesn’t compress enough to leave a comfortable space for the gun to sit in.
