New Lapua brass sized for the first time, is leaving grit in my dies and if not cleaned out builds up on case necks and will scratch the brass. Never had to deal with taking a die apart every three rounds to polish flaking brass out of neck. Tried sizing wax, silicone spray lube, bullet swage lube and just about every lube in my shop. Its not a lube issue its a flaking brass problem. The next box of brass will be washed with STM before I waste any more time polishing loading dies. Its happened with 222, 220 Russian, 6.5 X 47, 308, 308 Palma, and 6.5 X 55. Only the Lapua brass in the new plastic container has given me these problems. The 6.5-284 cases in the cardboard box are fine. Could there be some weird typhoid causing C7+ aromatic fumes in those boxes that is deteriorating the brass?
