Barrel Break-In Procedure


The purpose of a barrel break-in procedure is to limit buildup of copper fouling and to smooth out or polish any microscopic imperfections remaining from manufacturing. An excess of copper fouling can serve to increase chamber pressures, reduce velocity, negatively impact bullet stability and decrease barrel performance.

Some barrels may require more "shoot and clean" than others. The information below is only meant to be a guide to barrel break-in procedures. Your inspection of the barrel while completing the "shoot and clean" will tell you when the break-in procedure is complete. If copper fouling isn't reduced after each step, continue the "shoot and clean" until fouling begins to drop off. Once you see a reduction, move to the next step firing the suggested round count before cleaning and inspecting. 

• 1 Round - Repeat this step 5-10 times (5 - 10 rounds)
• 3 Rounds - Repeat this step 5-10 times (15 - 30 rounds)
• 5 Rounds - Repeat this step 5-10 times (25 - 50 rounds)
• 10 Rounds - Repeat this step 5-10 times (50 - 100 rounds)
