Introduction

Properly mounted scopes can have a significant impact on the accuracy of rifles. In this article, we will explore the step-by-step process of mounting a scope on a rifle presented by Larry Potterfield in a video produced by MidwayUSA Gunsmithing. We will discuss the equipment and accessories needed to mount the scope and tips to ensure maximum accuracy.

The Process of Installing a 3×9 Power Leupold VX-II Scope on a Pre-64 Winchester Model 70

In the video, Larry Potterfield demonstrates the proper technique for mounting a scope on a pre-64 Winchester Model 70. Here are the steps that he follows:

  1. Select a standard style two-piece ring and base combination.
  2. Remove plug screws from the receiver and degrease and oil the base mounting screws.
  3. Use medium strength blue Loctite to secure the screws, and the base screws are torqued to 30-inch pounds using Wheeler Engineering Fat Wrench.
  4. Use low rings to position the scope closely in line with the eye, and apply a small amount of grease to the dovetail to prevent galling.
  5. Use a Leupold wrench to turn the front ring easily, and secure the rear ring between two windage screws.
  6. If there is a spacing issue, use an extended front ring and medium-high to rings to correct it.
  7. Use Bars from the Wheeler Engineering Scope Ring Alignment and Lapping Kit to align the rings.
  8. Apply lapping compounds to the inside of both front and rear rings and tighten screws enough to achieve contact, but still allow the lapping bar to slide.
  9. Use a Wheeler Engineering Professional Reticle Leveling System to level the crosshairs.
  10. Place the scope as far forward as possible to provide maximum eye relief.
  11. Install the top halves of the rings with screws slightly loose, and place the small level on the top scope cap to level the crosshairs.
  12. Torque the ring screws to 15-inch pounds to hold the scope securely without damaging it from too much torque.
  13. The gun is now ready to be taken to the range and sighted in.

Tips for Maximum Accuracy

Now that we have gone through the steps involved in mounting a scope, here are some tips to ensure maximum accuracy:

  1. Always start by cleaning your firearm thoroughly to ensure maximum accuracy.
  2. Use a torque wrench to ensure that screws are tightened to the appropriate level, preventing damage and maintaining maximum accuracy.
  3. Use the smallest optics that will get the job done, as they are typically more accurate.
  4. Test your firearm on a bench rest to ensure that it is firing accurately before proceeding to hunt or compete.
  5. Always follow the instructions provided by the scope manufacturer to ensure that you are mounting the scope correctly.

FAQs

  1. Can I mount my scope without a torque wrench?
    A: It is not recommended as over-tightening can cause damage to your scope and under-tightening can cause it to move, reducing accuracy. It is best to invest in a torque wrench to ensure proper tightening.

  2. Can I use Loctite on all the screws?
    A: No, you should only use Loctite on the base mounting screws. Loctite on ring screws can make it difficult to remove the scope later.

  3. Do I need to apply lapping compounds to my scope rings?
    A: Lapping compounds are an essential part of the mounting process as they help align the scope rings, preventing any wobble, and ensuring maximum accuracy.

  4. Do I need professional help to mount my scope?
    A: While it is possible to mount your scope on your own, it is recommended that you seek the help of a professional gunsmith if you are unsure about the process.

  5. Does the size of the optic matter in mounting a scope?
    A: Yes, using the smallest optics that will get the job done is typically more accurate. Larger optics can be more cumbersome and less precise.
