Can You Use Match Ammo During Barrel Break-In?

Choosing the Right Ammunition

When breaking in a new barrel, it’s crucial to select the right ammunition. Match ammo can be used, but it’s recommended to start with a lower-powered load, such as 223 Remington or 308 Winchester, to avoid pushing the barrel too hard. For example, start with a 55-grain bullet and gradually increase the weight to 69-77 grains.

Break-in Procedure

To break in a new barrel, follow a step-by-step process. Begin by firing 20-30 rounds at a moderate pace, then gradually increase the firing rate to 20-30 rounds per minute. After every 20-30 rounds, inspect the barrel for any signs of wear or damage. It’s also essential to clean the barrel after each shooting session to prevent fouling. For a 223 Remington barrel, it’s recommended to break it in over 3-4 sessions, with a minimum of 60-90 minutes of shooting time.

Ammunition Selection Considerations

When selecting match ammo for barrel break-in, look for loads with a consistent velocity and pressure. Avoid using high-powered loads or those with excessive recoil, as they can damage the barrel. Some popular match ammo options for barrel break-in include the 223 Remington 55-grain and 308 Winchester 150-grain loads. Always follow the manufacturer’s recommendations and consult with a firearms expert if you’re unsure about the best ammunition to use for barrel break-in.
