Been reading a lot about taking care of your new rifle and then this topic came out. Did a search in huntingBC and 2 old threads, 6 years ago, comes out.

Now with another 6 years, has anyone proven that barrel break in is necessary/useful? And does everyone break in their new factory barrels? Or is it still a myth?

Oh and I came across this video too
