X-Caliber Barrel Break-In

Procedure Guide

 

When breaking in your new X-Caliber Barrel, you should perform appropriate fire and clean cycles to normalize the bore surface. Each fire and clean cycle consists of a certain number of rounds fired (one to five) followed by a cleaning procedure (see below for reference), to be completed a certain number of times (1-25). These vary depending on the type of steel of the barrel, bore/groove diameter, velocity and pressure of any given round, etc. This is to be used as a guide. Since our barrels are hand-lapped, each barrel may break in a little differently. Some barrels may require more or less shots or cycles to break in than what is listed here.

 

416R Stainless Steel: Fire One Round then Clean: Do this 5-10 times. Fire Three Times then Clean: Do this 1 time. Fire Five Times then Clean: Do this 1 time.

4140 Chrome Moly: Fire Once Round then Clean: Do this 5-25 times. Fire Three Times then Clean: Do this 2 times. Fire Five Times then Clean: Do this 1 time.

 

 Example: For a 416R Stainless Steel barrel, you would fire one round, then perform the cleaning steps outlined below a total of five to ten times (shoot 1 round & clean, done 5-10 times) before starting the three shot cycle where you would fire three rounds and then clean as outlined below, then proceed to fire five rounds then clean, completing the break-in procedure.

 

Each Firing Cycle (1 shot, 3 shot or 5 shot) should be followed by cleaning the bore (see steps below for reference):

 

1.)    Using a one-piece, coated cleaning rod with a properly sized bore brush (wet with your favorite non-foaming bore solvent), carefully clean the bore from the chamber end toward the muzzle (3-5 passes is usually sufficient). If you cannot clean from the chamber end, be sure to use a bore-guide so as not to damage the crown or muzzle end of the rifling. Let sit 30-60 seconds before moving on to the next step.

2.)    Push a dry patch down the bore. (2-3 times)

3.)    Put a few of drops of oil on a patch and push that down the bore so as to leave a thin film of oil inside the bore.

4.)    Begin a new cycle: Fire your next round or rounds in your next firing cycle and repeat cleaning as necessary.

  

It is recommended to keep a written tally of your current step within the process so if you get distracted you will know where you left off.

 

We use Mil - Spec parts for testing. If any Non Mil-Spec (Adjustable Gas Block, Heavy Buffer, Reinforced Springs, Light/Heavy BCGS, Piston Systems) parts are used, X-Caliber must be contacted. If not your firearm may not cycle properly.
