Yes I did re-trim. I measured quite a few and some had increased in length. Others I dropped into a Lyman case length gauge and if it tapped the table, I trimmed. In the end I trimmed them all with the Lee quick trim die and a rechargeable screwdriver. Too much work to measure them all. I reloaded the 308 and 223 cases, checked them in the Lyman gauge, and checked quite a few in the rifle chambers. All is fine now. I will stick with FL sizing. I will revisit the neck sizing issue when I learn more about it. As I said, I'm not that concerned about accuracy. They're very accurate for my purposes. I would like to extend case life, so it will be a future project. Thanks.
