I bought 500 pieces of primed pull-down LC 7.62x51 (308) from Wideners a few months ago, and the inner necks have black sealant still present. I know trying to drop powder through them will almost certainly result in powder granules adhering, and I am not sure I want to push them out of the way with the bullet. Anybody dealt with this? I will also have to run them through at least a neck-sizer as some of them have little creases & dings (and little nibbles from the collet puller), and then trim to an overall a few thousandths less than normal, but the big issue is the sealant: should I try to clean 500 pieces of brass one by one with some kind of solvent, or just drive on... it's always something...
