What eye relief is best for heavy recoil rifles?

Choosing the Right Eye Relief

When it comes to heavy recoil rifles with caliber sizes of 7mm and above, or rifles with a recoil force above 25 ft-lbs, a longer eye relief is crucial for maintaining a safe shooting position. A general rule of thumb is to look for scopes with an eye relief of at least 3.5 inches (89mm) to absorb the recoil force. This provides sufficient clearance to prevent the recoil from pushing the shooter’s face against the scope.

Measuring Eye Relief for Heavy Recoil

To ensure your scope has sufficient eye relief, it’s essential to know the rifle’s recoil characteristics. Measure the rifle’s recoil force using a recoil chart or consult with the manufacturer to determine the exact recoil force. Compare this measurement to the eye relief provided by the scope. As a general guideline, a 1-inch (25mm) increase in eye relief can reduce the recoil impact by 10%. This means that a 4-inch (102mm) eye relief can reduce the recoil impact by 40%.

Eye Relief and Scope Mounts

Proper scope mounting is also critical when dealing with heavy recoil rifles. Use a high-quality scope mount that can handle the recoil force and maintain the scope’s position. Look for mounts with a recoil rating of at least 50 ft-lbs to ensure they can handle the rifle’s recoil. When mounting the scope, ensure it’s securely fastened and the eye relief is properly aligned to prevent any movement during firing.
