Quick Answer
A scope that won't hold zero on a Remington bolt action rifle could be due to a misaligned scope, incorrect scope mounting, or a faulty scope adjustment system. It's also possible that the rifle is experiencing a shift in its point of impact due to worn or loose tolerances in the action. Proper diagnosis and adjustment are essential to resolve this issue.
Identifying the Problem
When a scope won’t hold zero, it’s crucial to first identify the root cause of the problem. Start by ensuring the scope is properly mounted to the rifle. Check the scope’s torque specification and make sure it’s tightened within the correct range, typically 10-15 in-lbs for many Remington bolt actions. If the scope was recently installed, double-check that all the mounting screws are tightened evenly and securely.
Adjusting the Scope
If the scope is properly mounted, the next step is to adjust the scope’s elevation and windage dials to zero the rifle. Begin by firing a shot and adjusting the scope to compensate for any windage or elevation errors. Record the adjustments made and re-zero the scope after each shot. For most bolt action rifles, it’s recommended to make adjustments in increments of 1/4 MOA or less to ensure accurate tracking. For example, if the scope requires a 2 MOA adjustment, divide this by 8 (since 2 MOA is equal to 8 clicks of 1/4 MOA) and make 2 clicks in the direction of the adjustment.
Checking the Rifle Action
In some cases, a scope that won’t hold zero may be indicative of a shift in the rifle’s point of impact. This can occur due to worn or loose tolerances in the action, which can cause the bullet to exit the barrel at a different angle than intended. To check the action, start by inspecting the rifle’s bolts, bolt faces, and ejector for any signs of wear or damage. If any issues are found, consider having the rifle serviced or repaired by a qualified gunsmith.
