On Our Mark: Episode 11 - Barrel Break-In
Barrel break-in can be performed through a number of different procedures. It is important to note that our testing shows that not all barrels require the same amount of break-in. Many of our Weatherby rifles get close to their accuracy potential during break-in but accuracy continues to improve with more shooting.
We suggest a 20 shot break-in, utilizing two different factory loads (load 1 and load 2) to begin understanding desired barrel accuracy. If desired, after the break-in, begin experimental shooting with different factory loads as each barrel's accuracy is dependent on load and bullet combinations.
Our procedure is as follows:
- Clean the barrel*
- Fire 3 shots (Load 1)
- Clean the barrel*
- Fire 3 shots (Load 2)
- Clean the barrel*
- Fire 3 shots (Load 1)
- Clean the barrel*
- Fire 3 shots (Load 2)
- Clean the barrel*
- Fire 3 shots (Load 1)
- Let Barrel Cool
- Fire 5 shots (Load 2)
- Clean the Barrel*
*Recommended Bore Cleaning Procedure:
- Run several patches with bore cleaner/copper solvent down the barrel
- Brush the barrel with at least 10 strokes
- Run 2 patches soaked in bore cleaner/copper solvent
- Brush the barrel with at least 5 strokes
- Run patches soaked in bore cleaner/copper solvent through until patches come out clean
- Run 2 dry patches through the barrel
- Run a small amount of lubricant through the barrel before storage
