Quick Answer
Steel-cased ammo can be used during barrel break-in, but it's not the preferred choice due to its potential to cause excessive wear on the barrel's rifling.
Choosing the Right Ammo for Barrel Break-In
When breaking in a new barrel, it’s essential to choose the right ammunition to avoid damaging the rifling or the barrel itself. Steel-cased ammo can be used, but it’s not the best option due to its tendency to cause excessive wear on the barrel. A better choice is to use full-metal-jacketed (FMJ) or jacketed hollow-point (JHP) ammunition, which is designed for smooth feeding and reduced barrel wear.
Barrel Break-In Techniques
To break in a new barrel, it’s recommended to start with a cleaning solvent and a soft-bristled brush to clean the barrel thoroughly. Then, shoot 10-20 rounds of full-power ammunition, followed by a cleaning session. Repeat this process 3-5 times, gradually increasing the round count each time. This will help to burnish the rifling and allow the barrel to settle in.
Safety Considerations
When breaking in a new barrel, it’s crucial to follow proper safety protocols to avoid damaging the barrel or the rifle. Always wear safety glasses, ear protection, and follow proper shooting procedures. Make sure the rifle is properly sighted in and that you have a clear shooting area. Additionally, keep track of your round count and cleaning sessions to ensure you’re not over-stressing the barrel.
