Some barrel makers recommend it while others do not which demonstrates a lack of universal agreement on whether it’s really necessary so it probably is not. Every formula for break in involves some combination of firing and cleaning. The fact that there are numerous different formulas should be evidence that nobody really has the definitive answer on the best procedure meaning there likely isn’t one. Simply shooting the rifle as intended will likely be all the break in that is required.
