[QUOTE="J E Custom, post: 1797840, member: 2736"] When a barrel is chambered, threaded and crowned There are cutting oils and machining chips left in the barrel. that MUST be removed to prevent damaging the bore or the chamber. After I do this work on a barrel, First I push a patch using a one size smaller jag through the bore to remove the bulk of these products of machining. then I push a dry patch through it to check for more of these products. Then with the barrel muzzle pointed slightly downward I swab the chamber and make sure it is clean before it is assembled and torqued in the action. To prevent any assembly lube from getting in the chamber it is cleaned one more time after assembly. The last step before firing the rifle, I do a solvent cleaning to remove any residuals and dry patch until the patch comes clean. I do this to prevent any foreign substances from damaging the bore the first time I fire it. You cannot be to careful and should make sure there is nothing that could scratch the bore left inside. I also do a break in and monitor the barrel condition as I go for best condition before starting load development. Many people don't go to this much trouble, But To damage an expensive barrel because of carelessness Just doesn't make sense to me. J E CUSTOM [/QUOTE]
