LOL.."breaking" in a barrel.
Barrel Break in is a theory..and really a good debate..
The way i look at it..if it gives you a warm fuzzy..go for it!
But more often than not people can ruin a barrel with a cleaning rod before their barrel is "broke" in.
• 99.9% of shooters don’t have access to a quality bore scope to view the interior surface of their barrels.
• Without a bore scope to view the interior surface of your barrel what exactly are you trying to fix by a shoot and clean process?
• If there are burrs or machine marks from the machining process in the chamber, throat or barrel where are they located?
• Do the machine marks run parallel or perpendicular to the barrel finish?
• If there are high points and low points inside the barrel again where are they located?
• Does shooting and cleaning between rounds correct/fix all barrel imperfections if they exist? If yes how?
• Without a bore scope again you have no idea what the actual condition of the interior barrel surface
• So far if you don’t have honest solid answers to these first few questions and you’ve been performing a barrel break-in process you’re working off a SWAG (scientific wild [beeep] guess)
• Pushing a cotton patch with solvent or a bronze brush down the barrel will do what to remove a 416 stainless steel or chromemoly metal burr or machine marks?
• Last time I checked, 416 SS or CM is much harder than a cotton patch or bronze brush and is most likely impenetrable by most bore solvents.
• Yes it will remove copper fouling caught by the metal burr, but how will it remove the metal burr?
• How many shots will it take to remove the burr or imperfection and how will you know when the barrel issues have been corrected? Is it always x-amount of shots?
Here is the best theory i found..
