Do I need to re-zero my scope after changing rings?

Why Re-Zeroing is Necessary

When you change scope rings, the scope’s position relative to the rifle’s barrel changes. This shift can affect the scope’s point of impact, causing your shots to land off-target. To maintain accuracy, you must re-zero your scope after changing rings.

Factors to Consider

The amount of re-zeroing required depends on the type of rings used and the scope’s adjustment range. If you’ve installed a new set of rings that are significantly heavier or lighter than the previous ones, you may need to re-zero your scope multiple times to find the correct adjustment. A general rule of thumb is to re-zero your scope for every 1-2 ounces of ring weight change.

Re-Zeroing Technique

To re-zero your scope correctly, follow these steps:

1. Mount the scope on the rifle with the new rings, ensuring it’s securely tightened.
2. Use a ballistic target or a known-distance target to zero in the scope. Start by making small adjustments (1/8 MOA or less) and re-shoot the target between adjustments.
3. Continue making adjustments until the scope is properly zeroed. You can also use a laser sight or a shooting machine to help with the process.
4. Once zeroed, make sure to record the adjustments made and update your rifle’s zeroing data for future reference.

Additional Tips

When re-zeroing your scope, keep in mind that the process may take some time, especially if you’re using a high-magnification scope or a rifle with a long barrel. Be patient and work methodically to ensure accurate results. Additionally, consider using a scope leveling tool to ensure the scope is properly aligned with the rifle’s barrel.
