How to avoid misfires when using .270 WSM?

April 5, 2026

Quick Answer

To avoid misfires when using a .270 WSM, ensure proper ammunition loading, maintain a clean rifle, and follow a consistent loading procedure. Keep the rifle's magazine and chamber free from debris and obstructions. Regularly inspect and clean the firing pin and extractor.

Proper Ammunition Loading

Proper ammunition loading is crucial to avoid misfires with a .270 WSM. Always use the correct caliber ammunition and ensure the primer is seated properly. Incorrect primer seating can lead to misfires, so it’s essential to use a loading tool or follow the manufacturer’s recommended loading procedure. Typically, a .270 WSM primer should be seated to a depth of 0.045 inches. Always verify the manufacturer’s specifications for the specific ammunition being used.

Rifle Maintenance

Regular rifle maintenance is vital to preventing misfires. The firing pin and extractor should be inspected and cleaned after every use. Any debris or carbon buildup on these components can lead to misfires. The magazine and chamber should also be cleaned regularly to prevent the accumulation of debris. A .270 WSM rifle should be cleaned after every 50 rounds fired, and the bolt should be removed and cleaned separately.

Consistent Loading Procedure

Developing a consistent loading procedure can help prevent misfires. This involves loading and unloading the rifle in the same manner each time. The rifle should be loaded in a well-lit area, and the magazine should be seated firmly in the rifle. Always verify that the bolt is fully closed and the rifle is on a safe setting before firing. It’s also essential to develop a pre-shooting routine that includes inspecting the rifle, checking the ammunition, and verifying the rifle’s safety status.
