Q: How many rounds does it take to “break in” a barrel?
A: They are several different procedures for breaking in a new barrel, although most use the same basic process. One popular method is to thoroughly clean the barrel between each of the first 15 to 25 shots, then between every two or three shots for the next 10 shots. Finally, several five- or 10-shot strings are fired with a complete cleaning between each. Barrel break-in is typically completed within 50 or fewer rounds and is usually signaled by a noticeable reduction in fouling during cleaning.
