Looking at all the videos on YT, I understand that consistency is paramount when chamfering, but I am seeing no real reference to the actual length of the chamfer. I understand about the concept of a large chamfer going to the outer edge of the case and it creating a "paper punch" sharp edge, but depending on the brass neck thickness, there is a large variation in the distance the chamfer can go into the neck without creating the sharp edge on the case. And this is also compounded with the cutting angle on the chamfer tool itself.
My thoughts are that we want to just break the inside edge of the case mouth so it doesn't peel the the bullet jacket as it is loaded, and it seems like that the longer the chamfer, the less surface bearing contact area is available to hold the bullet in the neck.
So, what in reality is the general consensus of how much the chamfer should be?
Thanks
