So I’m currently reloading for .308 and the book trim length for the cases is 2.005”. The brass I am using is Alpha Munitions brass and when I got them they were all exactly 2.005”. After 3 firings I see cases that are 1.997” to 2.006”. I have not done any trimming on these cases and all were FL sized with a 0.0015 shoulder bump. Is there an issue with shooting these shorter cases and worrying about the carbon buildup? I’m wondering if the longer cases will see weird pressure signs due to the carbon from the shorter cases... any info? The resizing was using a FL expander ball set up but I have now purchased a Redding Type S bushing die and removed the seating stem... could that help? Or hurt?
