It is a lot of effort for very little return. Unless you have a trued blueprinted custom rifles barrel, you will not be able to see the difference, if your rifle is all of the above, you may be able to see a difference. The guys who do this are shooting groups where .001” could be the difference between a win or a loss. All in all, for the average hunter/reloader, shooting off the shelf rifles, the juice is not worth the squeeze.
