When breaking in your new Dreadtec™ 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 guideline. Since our core 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 Cores:
Fire one (1) round then clean - Perform 5-10 times
Fire three (3) times then clean - Perform 1 time
Fire five (5) times then clean - Perform 1 time
For a Dreadtec™ 416R Stainless Steel core 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 log of your current step within the process so if you get distracted you will know where you left off.
