Shown are some .300RSAUM cases I have FL resized. I have an extra factory barrel identical to the one currently on my rifle that I use as a case gauge of sorts that I have dropped them in to. The case that will not drop into the barrel mics out at all the the same dimensions as the resized cases that will easily drop into the barrel. All cases are reloaded 3-5x and have only been shot in my gun. Why will the one case not drop in the barrel? It also will not allow the bolt to cam over when fed into my gun.
