Really more a side note to break-in in general and less relevant to the OP's issue, but:
Barrel break-in is, at best, a marketing gimmick to sell more barrels to the benchrest competition guys who replace their barrels after some arbitrary number of rounds down the pipe.
At worst, and in the cases where it might actually improve accuracy, its compensating for halfass barrel manufacturers that try to stretch the life of their cutting tools too far, resulting in dull carbides that make poor cuts and leave burred surfaces inside the barrel.
In any case, a new barrel from a quality manufacturer shouldn't need it.
BUT...for rust in the bore, its not a bad way to get it out. The heat and abrasion from the bullet will help dislodge the rust on the lands. For any rust that might be in the grooves of the rifling, there's probably no substitute for a stiff rod, brass brush, lots of oil and patches, and some old fashioned elbow grease.
