what is a barrel procedure

A barrel procedure refers to the process of breaking in a new rifle barrel to remove burrs and other imperfections through the heat and friction of a live-fire sequence. The process of breaking in a new barrel is essentially just conditioning the barrel to smooth everything out and remove small burrs. Proper barrel break-in consists of a series of shooting and cleaning sequences, and it is one of the most important and most misunderstood aspects of extracting the utmost accuracy from a rifle. The process of breaking in a new barrel can vary, but it generally involves firing a few shots and then cleaning the barrel with solvent and a bore brush. The goal of the process is to smooth the bore of the barrel to create better consistency and accuracy.
