Rifle barrels though mass produced is still a relatively custom affair. Meaning there is no specific standards or specifications the manufacturers go by. Some barrel makers have well over 100 unique profiles. Remington as well as many rifle makers profile barrels specific to whatever they are building. They have few standard profiles but many are specific to the model and year it's being made and it is subject to change as they see fit. To try to compile a cross reference list by exact duplicates is going to be a challenging task. I would think that a generous + or - tolerance would make it a little easier but may defeat the purpose you are trying to achieve.
