Varmint scopes are one of the best scopes. Magnification has to be 10x or under and having an adjustable parallax will be an advantage. For better accuracy have a look at this:
The very first thing to look at is mounts. They come in about two main heights and about two main widths. You need this to accommodate different tube sizes. Then you have the single or double strap and a single or double screw. Yet unless you want to spend a fortune on single-strap, single-screw and Leupold mounts. You have to then stick with a double screw single from either a BKL or Sportsmatch. The double-screw mount will give you both rigidity and even stability.
Eye relief and set-up
After attaching the base of the mounts to the rifle’s scope rail start placing the rifle. Place the rifle in a rifle stand or a Black and Decker Workmate that is if you have one. Now place a spirit level on the scope rail. Try adjusting until this rifle’s dovetail is perfectly level and is also stable. Place a telescopic sight in mounts, put the top of mounts on and then finger-tighten the screws. Make sure the scope is set up to 9 or 10 magnification. And if the scope has parallax adjustment then set to about 25 yards.
You have a need for setting up the plumb line with the nice heavy weight. A thick piece of rope and place that 20 yards in front of the unloaded rifle. Look through a scope at the plumb line. You may need adjusting fast-focus ring at the ocular end of the scope.
You now have to set parallax. Parallax error is a big reason for missing targets. Hold the gun out in the front and raise the index finger so it will point toward the ceiling. Just stay calm while closing one eye then stretch your arm. Then move the hand so that your finger will cover a point on that wall. Your finger here is the scope’s graticule and the point that will cover up the target.
So now, you have to move the head to the left. Almost all quality scopes contain parallax adjusters. This will enable you to setting the scope with a parallax of 40 yards for the 40-yard target. And for 10 yards for the 10-yard target is to be maintained.
Look through the scope of the box that is 45 yards away. Now set the magnification to 10 and then wind that parallax adjuster back to around 13 yards.
That will be all the necessary items for you. Remember these points, and you can have a good time with the scope. It is only normal for you to want the
