Nothing special. Many people have their own “special” criteria when breaking in a new barrel or target shooting. I never have. Most barrels now are hand lapped. I don’t believe in any routine, and I have background in metallurgical study that backs up my thoughts. I shoot my firearms, take them home & clean after each outing. That’s it. All that “shoot 5rds & clean...shoot 10rds & clean...” That’s all superstition & shooter’s creed! But to many, that stuff, although having no evidence beyond anecdotal, is just part of their dance.

What Robin just pointed out is all that’s needed.
