Breaking in your barrel will ensure 3 major components to give you success while shooting:

1). This process allows you to get out any microscopic imperfections that can remain in the barrel caused by the rifling process

2). Your barrel will shoot more accurately

3). The rifling inside your barrel will become smoother, avoiding any fouling that can occur as well as providing stress relief

​

The following is only a guide to rifle barrel break-in based on our experience, and is not intended as a complete step-by-step instructional tool, nor is it a recommendation for any specific product. Variables including caliber, barrel material, bullet design, velocity, etc. will all affect the break-in necessary – some combinations will require more cleaning cycles and some less.

 

One cleaning procedure is to run a cotton patch wet with solvent through the barrel. Then, wet a bore brush (brass or bronze) with solvent and stroke the barrel 8-10 strokes, followed by another patch wet with solvent. At this point, run a cotton patch with gun oil through the barrel, followed by a dry patch to remove any excess. Initially, you should shoot “ 5 shots clean and oil bore. 10 shots, clean and oil bore”. Then follow up with “20 shots, clean and oil bore”. Do this as you are sighting in your firearm. Continue with a normal cleaning routine with normal use.
