I was just sizing a ton of 223 brass, where we shoot this stuff is on sand. Everything was clean going in but I must have missed inside the case neck on one of them and appears the neck plunger pulled some sand out of the top and it slid out. All of a sudden all my brass is coming out like this. I can see scratches of sorts inside the die and wiped it well with a qtip but they remain. Can it be buffed out or am I best just replacing the die?
