Factors to Consider
Rifle Model and Action Type
Several considerations should guide your selection. The rifle model and action type are the most important factors. Different rifle designs require different types of bases.
Scope Objective Lens Size
The scope’s objective lens size also plays a significant role. Larger objective lenses might necessitate higher scope bases to clear the rifle’s barrel.
Desired Scope Height/Mounting Position
The desired scope height is another key consideration. Your desired eye relief and cheek weld will all be determined by the height of the base you choose.
Type of Shooting Intended
Furthermore, the type of shooting you intend to do should influence your decision. Target shooters may prefer a different base style than hunters.
Base Availability
Ensure the bases are readily available for your specific rifle. This will streamline the installation process.
Torque Specifications
The correct torque specifications will also be listed in the chart. Applying the correct torque when securing the bases and rings is critical to prevent movement and ensure consistent performance.
Installation Tips and Best Practices
Tools Needed
Installing a scope base correctly is a crucial step in achieving optimal accuracy. Before beginning, gather the necessary tools, including a torque wrench, screwdrivers, and thread locker. A torque wrench is essential for applying the correct torque to the screws, while thread locker will help to prevent the screws from loosening under recoil.
Step-by-step Guide to Mounting a Scope Base
Start by preparing the rifle receiver. Clean the receiver and remove any existing bases or screws. Then, align the bases on the receiver. This may require carefully positioning the front and rear bases to ensure they are correctly spaced and aligned. Secure the bases with the proper torque. Use a torque wrench and follow the manufacturer’s recommended torque specifications.
Checking Alignment and Ensuring the Scope is Level
Checking alignment and ensuring the scope is level are also important. These steps will ensure the scope reticle is aligned with the rifle’s bore and that your shots will land accurately. Improper alignment can lead to inconsistent point of impact.
Troubleshooting Common Issues
Base Fit Issues
Troubleshooting can be a necessity. Sometimes a scope base may not fit correctly. Ensure you’ve identified your rifle’s exact model when consulting the Leupold Scope Base Chart. Examine the base for any manufacturing defects. If the base consistently fails to fit properly, contact the manufacturer or consult a qualified gunsmith.
Scope Slippage
Scope slippage is another possible issue. Ensure your scope rings are properly tightened and that you are using thread locker on the base screws. A scope that shifts after installation will require re-tightening.
Screw Stripping or Breaking
The screws themselves are a common issue, as they can strip or break. Always use high-quality screws and avoid over-tightening. If a screw strips, it may need to be replaced. Careful installation practices, using the correct torque specifications, and applying thread locker are essential to prevent this.

In conclusion, choosing the right scope base is an essential element of any successful shooting setup. The Leupold Scope Base Chart is an invaluable resource. Mastering the chart will enable you to make informed decisions, leading to improved accuracy and a more enjoyable shooting experience.
By understanding the nuances of base selection and installation, you can ensure a stable and reliable platform for your scope, allowing you to maximize your rifle’s potential.
